Replacing the wiper motor on a VAZ 2114: doing it right

Failed wipers are not only unpleasant, but also dangerous, because a trip without them in bad weather can easily result in a traffic accident (and that is why operating a car with inoperative windshield wipers is simply prohibited). Today we will talk about the principle by which wipers work, why they fail, and also how to replace the windshield wiper motor of a VAZ 2114 yourself.

Windshield wiper motor VAZ 2114

Replacing a VAZ windshield wiper motor

Sometimes the gear motor fails.
The brushes are constantly working, the shutdown relay does not work. When the motor control is turned on, the wipers do not function. In some cases they do not turn off. To eliminate such breakdowns, the motor must be replaced. The windshield wiper gear motor is a very ordinary three-speed electric motor. Similar to standard geared motors, it has a bimetallic fuse located directly on the housing or hidden inside. Replacing the motor is quite simple. It is necessary to unscrew the four mounting bolts. However, the following difficulties may arise:

• poor engine location;
• the need to mark the location of the crank.

The crank refers to a curved rod that connects the motor and the trapezoid arms. If the crank is installed incorrectly, the teeth of the new motor can be broken. The replacement technology is as follows.

1. The fuse box is turned off.
2. A mark is made on the location of the crank.
3. The crank mount is released.
4. The trapezoid mounting bolts are unscrewed.
5. The gear motor is removed.

Sometimes the motor is difficult to reach due to its location. For convenience, you need to move the fuse box, having first unscrewed the fastening bolts.

Device

Wipers on the VAZ 2114 are a fairly simple device. The entire structure includes a wiper arm as well as a rubber gasket.

In general, the cleaning scheme consists of the following elements:

• the brushes themselves, designed to clean the windshield and rear windows;
• a trapezoid that controls the synchronized movement of the wipers;
• wiper motor, which sets the entire structure in motion after its activation via the steering column switch in the car interior;
• level sensor - the washer fluid level regulator is designed to control the volume of consumables in the expansion tank.

Why the VAZ-2114 wipers don’t work and what to do

The windshield wipers on a VAZ car must ensure that the windshield and rear glass are cleared of precipitation that prevents the driver from concentrating on the road. If the windshield wipers do not work on your VAZ-2114, then it is unsafe to drive onto the road in rainy weather. To quickly solve the problem, you can try to repair them yourself. Any successful repair requires knowledge of the design of the broken unit.

Windshield wiper installation process

Replacing VAZ wipers is carried out in the following sequence:

1. Open the hood of the car.
2. Check battery disconnection.
3. Insert the new assembly into the hole. Connect the plastic fastener to the wires.

Installing a new node

1. Tighten the lower bracket of the mechanism with a bolt.

Bottom mounting bolt

1. Connect the wiring harness to the block.

Connect the wiring harness to the block

1. Close the hood.
2. Place a rubber gasket on the upper mount of the purifier bracket and tighten it with a nut.

We put on the rubber gasket and tighten the nut

1. Cover the nut with a protective cap.

We put on the protective cap

1. Install the lever on the motor.

Installing the windshield wiper arm

1. Securely tighten all purifier mounting nuts.

After installing the wipers, turn them on and check for squeaking and the degree of cleaning of the glass surface.

The size of the product plays an important role when operating a car. If you install a part that is larger than the original, then the force of pressing the brush on the glass will not be sufficient to cope with the contamination. The edge of the brush will begin to cling to the rubber seal, resulting in poorly cleaned glass.

Installation proceeds strictly in the reverse order, after first replacing the rubber seals. Also, when installing the casing, it is recommended to use new clips, since they are inexpensive.

Modern wipers

If it so happened that you had to replace the stock wipers with new ones on your VAZ 2114, give preference to modern windshield wipers.

Their advantages are obvious:

• High reliability indicators compared to outdated designs;
• Long service life;
• No squeaks during operation;
• Effectively perform your task - cleaning glass.

Particular attention should be paid to the new frameless windshield wipers. Their design does not provide for the presence of a skeleton. Basically, it's a kind of tape with a steel plate inside

Externally, they perfectly match the design of the VAZ 2114, which is seriously ahead of their frame counterparts

Essentially, it is a kind of tape with a steel plate inside. Externally, they perfectly match the design of the VAZ 2114, which is seriously ahead of their frame counterparts.

Frameless wipers are not a cheap pleasure and you need to choose them individually for a specific car model. Price tags start from 1000 rubles, and these are far from the best representatives of the premium brush segment.

But frameless devices perform excellently in winter, they perfectly clear snow and ice from the windshield, have excellent aerodynamics and increase downforce when driving at high speeds.

Windshield wipers are an important element of every car, violation of the functionality of which can affect not only comfort, but also traffic safety. Poor driver visibility of the road leads to dire consequences, so make sure your windshield wipers always work properly.

Why are my wipers slow?

Water and dirt accumulate on the windshield when it rains, snows or blows dust. To get rid of this, the design of the car provides for the presence of special elements - wipers.

Switches

Inside the cabin, at the driver’s fingertips, there is a wiper speed control. Brushes can be of different sizes and work in different modes.

If we talk about wipers on the VAZ 2114, they have four operating modes:

• Interrupts
• At first speed;
• At second speed;
• Along with the washing machine.

There are two modes on the rear window:

• With a washer;
• No washing machine.

Dimensions

After all, the size of the wipers on the VAZ 2114 plays a rather important role in the quality and efficiency of glass cleaning.

Wiper connection diagram

Small brushes are also not suitable, because then the cleaning area is reduced and not the entire surface of the glass is cleaned, which would provide the necessary visibility for the driver.

So what size should these same brushes be in the case of the “fourteenth model”?

1. The windshield of the VAZ 2114 has two blades of the same size - 51 centimeters. The driver's side blade can be replaced with a 53 cm long element, but it is important to leave 51 cm on the passenger side, otherwise there will be a strip of clean water on the glass between the driver and passenger.
2. The rear window of the VAZ 2114 also has a cleaner. But in this case, the element size is 30 centimeters. The vacuum cleaner can be installed at a height of 33 centimeters, which allows it to perfectly adapt to the size of the rear window. Some even install components at 40 centimeters, but in this case you will have to increase the wiper travel limit. To do this, we remove the motor, move the teeth of different units and install it.

Car owners are often faced with a situation where the wipers on a VAZ 2114 do not work properly. The causes of problems may vary, so you need to carefully examine the problem and then take appropriate action.

Typical failures include:

• They work constantly;
• The wipers can work independently, although the driver has not turned on or pressed anything;
• It may be too slow;
• Spontaneous combustion occurs.

Replacing the motor

In practice, in several cases it may be necessary to replace the wipers on a VAZ 2114. The most common is the failure of the gear motor.

There are several reasons:

• The brushes work constantly, the shutdown relay does not work;
• Turning on the regulator does not allow the wipers to start;
• Sometimes the wipers simply do not turn off when the corresponding buttons are pressed, etc.

To avoid breaking the teeth of the new gearmotor due to the crank (the curved rod connecting the motor and the trapezoidal arms), proceed as follows:

1. Disconnect the fuse.
2. Mark the position of the handle.
3. Disconnect the connecting rod mounts.
4. Unscrew the trapezoid mounting bolts.
5. We remove the engine.

Trapezoid repair

If the wipers on a VAZ 2114 work slowly, this indicates the need to repair the trapezoid. Although this cannot actually be fixed, it is enough to replace the failed element.

Replacing the trapezoid

Replacement will be required in case of mechanical damage. The procedure is quite simple, but here you must follow a certain sequence.

1. Disconnect the wires under the hood that connect to the fuse box.
2. Remove the heater fan protective cover.
3. Remove the heater (stove) filter.
4. Turn off the stove motor. It just slides to the side, no need to disassemble it.
5. The cover is removed from the windshield wiper.
6. Under the rubber boot there is a nut that holds the wiper in place. The lid should be slightly raised and the nut will be easy to unscrew. Remove the windshield wiper.
7. Remove the rings and spacers from the wiper shaft.
8. Do a similar procedure with the second wiper.
9. Under the hood, unscrew the bolts connecting the trapezoid to the body.
10. We remove the fuse box and the stove motor, or unscrew the gear motor from the trapezoid, after which the motor and trapezoid are removed one by one. There are two ways to get a broken trapezius.

Washing system diagram

Malfunctions and methods for eliminating them are different. Let's get to know them in more detail.

1. The steering column switch does not work. Verify this by shorting the two terminals under the steering wheel - front terminal 53ah-w, rear terminal 53ah-wh, then measure the resistance. If it is low, the switch is replaced with a new one.
2. Water does not flow through the washer pump. It should also be replaced.
3. Dirt has formed in the injectors. Use a sharp needle to clean them.
4. Broken wire connecting the pump and the switch. You yourself understand that the only option is replacement.
5. Faulty relay K3. Again, you have no choice but to change the relay.
6. The tube burst, its integrity was damaged. What do you think should be done in such a situation? Right: change handset.

If it so happens that you had to replace the standard wipers on a VAZ 2114 with new ones, give preference to modern wipers.

No frame

Their advantages are obvious:

• High reliability indicators compared to outdated projects;
• Long duration;
• There is no creaking during operation;
• Perform your task efficiently: glass cleaning.

Frameless wipers are by no means a cheap pleasure and they need to be selected individually for a specific car model. Price tags start from 1000 rubles, and these are far from the best representatives of the premium brush segment.

But frameless devices perform well in winter, ideally clear snow and icing from the windshield, have excellent aerodynamics and increase downforce when driving at high speed.

Windshield wipers are an important element of any car, the failure of which can affect not only comfort, but also traffic safety. A poor view of the road from the driver's side leads to dire consequences, so make sure that the wipers always work properly.

I welcome you, friends, to the do-it-yourself car service website. Windshield wipers are an indispensable attribute of any car.

The main thing is that they are in good condition and ready to work. In this case, the main element responsible for engine operation is the wiper motor.

Most cars are equipped with two blades, which provide a more effective cleaning of the windshield. The rear window is usually equipped with only one wiper.

The device operates in two or three modes that allow the brushes to provide intermittent, slow or fast cleaning.

One of the most unreliable elements of the system, which often fails, is the engine. In the event of a breakdown, motorists do not know what to do and what the reasons may be.

1. The electric motor does not work, the bimetallic fuse does not work, and the fuse insert responsible for powering the wipers is working. In this case, it is necessary to check the functionality of the wiring, the quality of connections of all contacts, determine any existing damage and eliminate them.

If everything is fine with the wiring, you should check the wiper switch. If it disappears, replace it. The motor itself may fail - this often happens when brushes stick together or contact connections burn out.

Water and dirt accumulate on the windshield when it rains, snows or blows dust. To get rid of this, the design of the car provides for the presence of special elements - wipers.

Switches

Schematically, wipers look quite simple: brushes, consisting of a lever and a rubber gasket, move in a certain direction and thereby clean the surface. The wipers are driven by a special gear motor. This allows the devices to clean the front and rear windows of the car.

If we talk about wipers on the VAZ 2114, they have four operating modes:

• Interrupts
• At first speed;
• At second speed;
• Along with the washing machine.

There are two modes on the rear window:

• With a washer;
• No washing machine.

It’s remarkable, but for some reason on the VAZ 2114 there are fewer situations when the rear wiper does not work than in the case of the front wipers. Most likely, it depends on the intensity of use of the front and rear wipers.

Dimensions

After all, the size of the wipers on the VAZ 2114 plays a rather important role in the quality and efficiency of glass cleaning.

If the standard length of the brushes is exceeded, the force of pressure of the brush on the glass decreases, which reduces the effectiveness of cleaning the surface. Additionally, a device that is too large may begin to touch elements that no longer belong on the windshield. For example, the edges of doors.

Small brushes are also not suitable, because then the cleaning area is reduced and not the entire surface of the glass is cleaned, which would provide the necessary visibility for the driver.

1. The windshield of the VAZ 2114 has two blades of the same size - 51 centimeters. The driver's side blade can be replaced with a 53 cm long element, but it is important to leave 51 cm on the passenger side, otherwise there will be a strip of clean water on the glass between the driver and passenger.
2. The rear window of the VAZ 2114 also has a cleaner. But in this case, the element size is 30 centimeters. The vacuum cleaner can be installed at a height of 33 centimeters, which allows it to perfectly adapt to the size of the rear window. Some even install components at 40 centimeters, but in this case you will have to increase the wiper travel limit. To do this, we remove the motor, move the teeth of different units and install it.

• Disconnect the negative battery terminal
• Turn both windshield wiper arms to a vertical position and unscrew their fastening nuts.
• Removing the wiper arms from the wiper rollers

• The nuts securing the brush arms are unscrewed, after which they can be removed from the conical grooves of the drive. If this is difficult, a penetrating lubricant can be applied to the grooves.
• The brush lever drives are disassembled by unscrewing the lock nuts, then the plastic bushings and rubber seals are removed.
• The terminal block in the harness is disconnected and removed by lifting the tab of the gasket through a slot in the engine compartment bulkhead.
• The next step is to directly remove the wiper. Then the washer and spring clip are unscrewed from it, and the thrust is turned off.
• By unscrewing the three mounting bolts, you can remove the motor.

1. The fuse responsible for the operation of the windshield wiper motor has blown. In this case, it is necessary to check its integrity in the fuse box and, if necessary, replace the blown one with a new one.
2. Poor connection of the power plug of the wiper motor itself. Try disconnecting and reconnecting the microcircuit, and also inspect the contacts inside them.
3. Windshield wiper motor malfunction. It happens very rarely, since the design is quite reliable. But if such a problem occurs, it will be necessary to replace the burnt part.
4. The wiper control mechanism on the VAZ 2114, or rather the trapezoid, has broken down. Carefully inspect the trapezoid and check to see if one of the rods is loose. If a malfunction is detected, you should fix it yourself or replace this design.
5. Trapezoid jam. A similar malfunction can often be observed when the keystone bushings become sour and the wipers begin to jam. Disassembling and lubricating the structure will help solve this problem.
6. The windshield wiper switch is faulty. The solution is to replace the steering column switch.

• drive (electric motor with a long shaft);
• adapter;
• lever system (trapezoid).

The most common causes of this malfunction are:

1. The problem is with the contacts. Often the cause of this behavior is the contact group of the gearmotor, malfunction of the motor limit switch. Stop the wipers in the middle of their stroke without turning off the ignition, check the voltage at the wiper wire connector, it should be 12v. Check the condition of the fuse.

1. Violation of the integrity of the splines. If the car is not new, and the wipers have to work frequently, then a broken teeth of the windshield wiper drive splines or simple abrasion of the splines may well be the reason why the wipers do not return to their place. Alternatively, the splines could simply jump, as a result of which the brushes simply do not return to their original position. As a rule, this breakdown is characterized by the fact that the motor makes noise, and the wipers themselves do not return to their place. This can be treated by replacing damaged gears or simple adjustments. To do this, you need to disassemble the windshield wiper drive gear, adjust the closer, lubricate them if necessary, check the contacts or completely replace the gear motor.

No less commonplace is the malfunction of the wipers associated with improper assembly of the glass wiper elements. Sometimes, when replacing a windshield or repairing the blades themselves, the assembly is not performed correctly, after which a situation arises when the wipers do not return to their original position. Make sure that the wipers are put on the slots correctly, check the motor and the trapezoid, perhaps it is not positioned correctly

Pay attention to the crank element of the windshield wiper drive; before dismantling one or another element, you should remember its position and do not confuse anything during assembly

1. The problem may lie in the drive (motor) itself or its switch; in such cases, you will have to repair or completely replace the above elements.

There can be quite a few reasons why wipers do not return to their place, from trivial to very complex; it is quite difficult to foresee and list them all, it all depends on the specific car model and the breakdown itself. If nothing works out for you, contact a specialist; a service station will definitely help you eliminate this unpleasant malfunction. This concludes our article on wiper malfunctions, until we meet again, take care of yourself.

Z.Y. If you know of other reasons why the windshield wipers do not return to their original position, you can share them using the comment form.

When the relay is triggered, the electric motor does not start

The cause of failure of the electric motor may be either a blown fuse or the motor itself. Fuses must be tested for functionality. If they are in working order, you need to inspect the trapezoid located under the hood; perhaps it has become deformed or a foreign object has gotten into it. In severe frost, again, you should check whether the blades are frozen to the windshield.

If the trapezoid is normal and the wiper blades move freely, you should definitely check the electric motor. To exclude other malfunctions, it should be removed from the car and connected directly to the battery. If it starts working, then it’s time to look for the cause in the electrical circuit.

Removal, repair and installation of a windshield wiper

You will need: keys “10”, “24”, screwdriver.

1. Disconnect the wire from the “–” terminal of the battery.

2. Turn both brush arms to a vertical position and unscrew the nuts securing them.

3. Remove the blade arms from the windshield wiper rollers

Note. If the lever cannot be removed by hand, unscrew the lever securing nut without unscrewing it completely so as not to damage the thread. Using pliers, pull the lever off the shaft splines, completely unscrew the nut and remove the lever.

4. Remove one protective cap from both sides.

5. Unscrew one nut of the upper bracket fastening on both sides.

6. Remove the rubber leveling washers from both sides.

7. Open the hood and disconnect the wiper wiring harness connector. Then move the heater fan to the right along the compartment in front of the windshield (see “Removing and installing the heater fan”), otherwise it will interfere with the removal of the windshield wiper.

The main reasons for the failure of wipers on the VAZ 2114

Below you can list the main causes of this breakdown and methods of elimination:

1. The fuse that controls the operation of the windshield wiper motor has blown. In this case, it is necessary to check its integrity in the mounting fuse block and, if necessary, replace the burnt one with a new one.
2. Poor connection of the power plug of the wiper motor itself. Try disconnecting and reconnecting the chip, and also inspect the contacts in them.
3. Failure of the windshield wiper motor. This happens extremely rarely, since the design is quite reliable. But if this problem occurs, it will be necessary to replace the burnt part.
4. The mechanism for driving the windshield wipers on a VAZ 2114—more precisely, the trapezoid—has broken down. Carefully inspect the trapeze and check to see if one of its rods has come off. If a breakdown is detected, it should be repaired yourself, or the structure should be replaced.
5. Trapezoid jamming. You can often observe a similar malfunction when the trapezoid bushings turn sour and the wipers begin to jam. Disassembling and lubricating the structure will help deal with this.
6. Failure of the wiper switch. The solution is to replace the steering column switch.

Listed above are the main problems that may arise and ways to eliminate them.

The windshield wiper on Samara 2 (VAZ 2114) is broken, help!

• Wipers do not return to their original position on the VAZ 2115 - 3 answers
• Why do the windshield wipers turn on spontaneously, VAZ Samara 2? – 2 answers
• Why, in the third position of the windshield wiper switch, do the wipers barely move? – 1 answer

Rear, front? In all modes or only in one?

If the front wipers do not work in the first, intermittent mode, the relay in the mounting block (K3) is to blame. Or a steering column switch.

If the front wipers do not work in the second mode, the problem is with worn blades or their freezing.

If the front wipers do not work in the third mode, most likely the fault is in the third blade, which is offset from the geometric neutral.

If the front wipers do not work in the fourth mode, the cause of the breakdown is in the relay or switch.

If the windshield wiper does not work in all modes, you need to look at fuses F7 and F16, test the wiring to the electric motor and check the ground connection. If everything is in order, the problem may be in the engine itself.

In the cold season, when snow falls and frosts strike, it is better to remove the wipers from the glass, otherwise they may freeze.

Trying to use flimsy windshield wipers to shake off the snow that has fallen overnight from the glass is also unnecessary.

Rear “wiper” - the rear window cleaner is located on the rear door of VAZ 2108, 2109 cars. It consists of a gear motor, a lever and a brush (“wiper”). The rear window washer consists of an electric motor in the washer fluid reservoir, an electromagnetic valve for turning on the rear window washer, pipes through which washer fluid is supplied and a nozzle above the rear door.

Features of electrical circuits for turning on the rear window cleaner and washer (rear wiper)

— Electric current enters the system for turning on the cleaner and washer from terminal “30” of the generator, when contacts “30” and “15/2” of the ignition switch are closed.

— The steering column switch (right, terminal “53ah”) receives current from the ignition switch, through fuse No. 4 (F7) and block Ш3 (Х3) of the mounting block.

— When contacts “53ah” and “53H” of the steering column switch are closed, the wiper motor on the rear door of the car is turned on; when contacts “53ah” and “WH” are closed, the rear window washer is turned on.

Wiper device

Structurally, the wipers are an electric motor with a built-in gearbox (geared motor), which transmits movement to a trapezoid, a system of levers.
In turn, the trapezoid of the VAZ 2114 wipers drives the brushes, which mechanically clean the glass. The windshield wiper operates in 3 modes:

• continuously at 1st speed;
• continuously at 2nd speed;
• intermittent.

In addition, it can be turned on both synchronously with the washing machine and operated without it.

A faulty windshield wiper motor can be identified by the following external signs:

• The windshield wiper blades stop after turning on the vacuum cleaner (in all modes), the sound of the electric motor is not heard;
• wipers move very slowly or freeze periodically;
• the brushes are motionless, but the gear motor is working;
• The wipers only move in one direction and then stop.

VAZ 2114 wipers trapezoid

It is worth noting that the error in the above malfunctions can be not only the gear motor, but also other components of the wiper, in particular the VAZ 2114 trapezoid. When starting repair work, this is its condition (integrity of connections, absence of deformation of the arms) and first you need to check and then move on to the engine itself.

It's also worth noting that if your windshield wipers fail or don't work properly intermittently, it could be the steering column switch itself or the relay that controls its operation. In both cases, these elements should be checked (in the case of a relay, by installing a similar model that is known to be good) and replaced if necessary.

Also, with the wipers completely stopped and the engine not running (regardless of the selected mode), you need to check and, if necessary, replace the bimetallic fuse with number F16 in the general block (and if the rear wiper does not turn and is lit, then you need to check fuse F7).

Modern wipers on the VAZ 2114

To clean the windshield of the VAZ 2114 from dirt and dirt during rain, a special device is provided, the so-called VAZ 2114 windshield wipers. The gearbox of the windshield wiper motor forces the blades to move back and forth.

The result is a clean windshield or rear window. Inside the car there is a speed controller for the windshield wipers. He is almost always behind the wheel. The size of the brushes can be very different. Almost all car windshield wipers operate in several modes. The windshield wiper operates on 4:

• interrupts when paused;
• 1st speed;
• 2nd speed;
• work with the puck.

The rear window has two modes:

Functionality and quality of modern windshield wipers

It must be said that the quality of the windshield wiper blades and their size have a huge impact on the safety of the car.

Therefore, choosing the right windshield wiper remains a very important task. The reliability and quality of cleaners is determined by the fact that they:

• keep quiet;
• have a long service life;
• Ideal for cleaning glass.

If at least one of the properties described above is absent, there is no comfort in the car, and there is a danger of getting into an accident due to limited visibility, especially in the rain. The size of the windshield wiper blades plays an important role. If this is a little more than necessary, then the force of the brush on the glass, especially when it is a frameless wiper, is noticeably reduced. As a result, the glass does not clean very well.

In addition, a large brush size will affect the cleaning plane. The brush may touch the rubber of the windshield with its edge, then it does not touch the working surface. On Kalina's car, the large brush begins to touch the edge of the driver's door. When the brush size is much smaller than required, a decrease in the cleaning area is observed. The windshield does not clean one hundred percent.

At the same time, small wipers leave a dirty island on the glass. What should be the size of the brushes on the VAZ 2114? This car model comes with 2 windshield wipers. They have a uniform symmetrical size of 51 cm. However, it is possible to install the brushes with a slight change in size.

On the driver's side, the brush can be 53 cm long and 51 cm on the passenger side. When installing similar brushes 53 cm long, a small strip of water is formed in the center of the glass. The rear window of the car is also equipped with a windshield wiper.

The size of the brush in this case is no more than 30 cm. It is allowed to install a wiper with a length of 33 cm. It fits perfectly into the size of the glass. Some car owners even install a brush 40 cm long, but they require a special increase in stroke.

In other words, the wiper should not touch the glass seal. To do this, remove the motor, run a few teeth and install it in place.

Replacing a VAZ windshield wiper motor

From time to time the gear motor fails. The brushes work constantly, the switch does not work. The windshield wipers do not operate when the engine controller is turned on. In some cases they are not turned off. To eliminate such damage, the engine must be replaced.

windshield wiper motor gearbox included in the VAZ

21083 group of channels in contact.

The windshield wiper motor is the most common three-speed electric motor. It, like standard gearboxes, has a bimetallic fuse, located specifically on the housing or hidden inside. Replacing a motor is quite common. It is necessary to unscrew the four mounting bolts. But the following problems may arise:

• poor motor placement;
• It is necessary to mark the location of the crank.

Why does the rear wiper of the VAZ 2109 not work? Troubleshooting and repair

Windshield wipers, wipers, brushes are essentially the same thing. As a rule, we remember their existence only when it starts to rain or when another bird flying by promises us great wealth right on our face :-). It is then that we remember the existence of these miracle devices that can so easily and effortlessly do all the dirty work or simply provide us with normal visibility in the rain, necessary for safe movement.

According to the “law of meanness,” the wipers will stop working exactly at the moment when it rains, snows, or when the glass needs cleaning. But this doesn’t make it any easier; the fault needs to be eliminated, but before that it wouldn’t hurt to find it. In practice, it turned out that finding the reason why the engine does not start is much easier than understanding why the rear wiper of a VAZ 2109 does not work. To be honest, at first, I didn’t even know where to start and what to actually check, the mechanism is as simple as “two rubles” and what -there can be no failures, but the fact remains that the wiper does not work and does not react to anything.

As you may have guessed, today we will talk about the rear wiper, or more precisely, about why the rear wiper of the VAZ 2109 does not work.

So, let's figure out what, how and why.

Windshield wipers do not work: the motor turns and the blades are in place:

• The reason for this may be poor contact or severe wear of the gearbox drive shaft.
• The nut securing the trapezoid to the drive has come loose.

The rear wiper does not work and there is no sound from the motor:

• Perhaps the steering column wiper switch has failed. Check the voltage on the wires with a tester.
• The windshield wiper drive (motor) itself has failed.

Frameless wipers: features

This design does not have its own skeleton. Basically, frameless wipers are a kind of tape that has a steel plate inside. Their appearance harmonizes perfectly with any car, which cannot be said about the skeletons of frame wipers.

These models do not belong to the economy segment. For different brands of cars, such wipers are selected individually. The curvature of the windshield of any car is formed according to aerodynamic parameters. Therefore, the curvature of the wiper must also be appropriate.

This is why low-cost windshield wipers do not press well and the glass does not clean. It is impossible to fix such brushes. You just need to install new, better ones. Premium brushes will work perfectly, regardless of the car model. However, they cost more than 1000 rubles.

A positive quality of frameless models is the ease of cleaning the windshield wiper from ice in winter. You just need to bend them a few times for the ice to instantly fall off. These wipers have excellent aerodynamics. At high vehicle speeds, their downforce increases.

Replacing the windshield wiper trapezoid:

Note! Before you begin, remove both wipers from the trapeze shaft!

1) At the beginning of the operation, de-energize the battery by removing the “-” terminal from it. (If you have never worked with a battery and do not know how to remove the “-” terminal from it, then read the article in which all the details are indicated. And the article is called: “Replacing the battery”, point “1”)

2) Next, remove the mounting block from the engine compartment of the car. (How to remove the block, see the article: “Replacing the mounting block”)

3) Then remove the wipers from the car. (For how to remove wipers, see the article: “Replacing windshield wipers”)

4) Next, disconnect the block and the wiring harness of the windshield wiper motor gearbox.

5) Then, using an extension with a socket head, unscrew the lower bolt that secures the windshield wiper trapezoid to the car body.

Note! When the bolt is unscrewed, pay attention that under this bolt there is a ground wire, so when unscrewing the bolt, be careful not to damage the wire!

6) Then remove the plastic wire holder from the body so as not to lose it later when removing the trapezoid.

Note! When the holder is removed, straighten it with your hands and, as a result, remove it from the wires!

7) Now remove both rollers of the windshield wiper trapezoid from the holes.

Finally, remove the windshield wiper trapezoid outwards, through the widest part of the compartment in front of the windshield.

Note! Install the windshield wiper trapezoid in the reverse order of removal!

-windshield wiper gearbox

If upon inspection it turns out that the reason for the non-working wipers was the VAZ 2114 windshield wiper motor, then it should be replaced, which will require:

• flat blade screwdriver;
• a set of heads and handles (or a pair of keys for 10 and 13);
• new gear motor.

The replacement itself in this case should be carried out in the following order:

Remove the ground (negative) terminal from the vehicle battery.

At this point, the process of disassembling the windshield wiper motor can be considered completely completed. Assembly and installation are carried out in the same order, but in reverse order.

When installing a new gearmotor, it is important to place the shaft in the correct starting position before connecting it to the crank. To do this, it is necessary to turn on the engine, not connected to the trapezoid, to the on-board network through a switch, switching the latter to intermittent mode. After stopping and stopping the crankshaft, it will be in its original position.

After completing the replacement of the wiper motor, you need to connect the negative terminal to the battery and check the operation of the wipers in all modes. If the problem persists (for example, the wipers move to their extreme position and stop), you should also check other components in the electrical circuit, such as control relays or keystone limit switches.

In conclusion, it is worth adding that in order to extend the service life of the wipers, it is necessary to periodically (for example, once a year) carry out their complete disassembly and inspection (for example, the presence of bending of the connecting rods or the appearance of the gaps in the moving joints). Such timely elimination of minor mechanical defects will reduce the load on the electric motor and, as a result, extend its service life.

Functionality and quality of modern wipers

It must be said that the quality of wipers and their size have a huge impact on the safety of the vehicle. Therefore, choosing the right windshield wiper remains a very important task. The reliability and quality of wipers are determined by the fact that they:

1. do not make creaking sounds;
2. have a long service life;
3. Cleans glass very well.

In the absence of any of the qualities described above, the comfort of being in the car is lost, and there is a danger of getting into a traffic accident due to reduced visibility, especially in the rain. The size of the installed wipers plays an important role. If it is slightly larger than required, then the force pressing the blade against the glass, especially when these are frameless wipers, is noticeably reduced. As a result, the glass is poorly cleaned.

In addition, a large brush size will affect the cleaning plane. The edge of the brush may touch the sealing rubber of the windshield, and then it does not touch the working surface. On Kalina's car, the large brush begins to touch the edge of the driver's door. When the brush size is much smaller than required, the cleaning area decreases. The windshield does not clean completely.

At the same time, small wipers leave a dirty island on the glass. What should be the size of brushes on a VAZ 2114? This car model is equipped with two wipers that clean the windshield. They have the same symmetrical size, equal to 51 cm. However, it is possible to install brushes whose size will be slightly changed.

On the driver's side, the blade can be 53 cm long, and on the passenger side - 51 cm. When installing identical 53 cm blades, a small strip of water will begin to form in the center of the glass. The rear window of the car is also equipped with a windshield wiper.

The size of the brush in this case does not exceed 30 cm. It is allowed to install a wiper 33 cm long. It fits perfectly into the size of the glass. Some car enthusiasts even install a brush measuring 40 cm, but for them it is necessary to specifically increase the stroke limit.

In other words, the wiper should not touch the glass seal. To do this, you need to remove the motor, move a few teeth and put it in place.

Replacing a VAZ windshield wiper motor

Windshield wipers Sometimes the gear motor fails. The brushes are constantly working, the shutdown relay does not work. When the motor control is turned on, the wipers do not function. In some cases they do not turn off. To eliminate such breakdowns, the motor must be replaced.

The windshield wiper gear motor is a very ordinary three-speed electric motor. Similar to standard geared motors, it has a bimetallic fuse located directly on the housing or hidden inside. Replacing the motor is quite simple. It is necessary to unscrew the four mounting bolts. However, the following difficulties may arise:

1. poor engine location;
2. the need to mark the location of the crank.

The crank refers to a curved rod that connects the motor and the trapezoid arms. If the crank is installed incorrectly, the teeth of the new motor can be broken. The replacement technology is as follows.

• The fuse box is turned off.
• A mark is made on the location of the crank.
• The crank mount is released.
• The trapezoid mounting bolts are unscrewed.
• The gear motor is removed.

Sometimes the motor is difficult to reach due to its location. For convenience, you need to move the fuse box, having first unscrewed the fastening bolts.

Causes of malfunction and their elimination

It often happens that the wipers do not respond to switching modes.
If you turn on the wipers and when you switch the lever you do not hear the sounds of the electric motor or the clicks of the relay, the reason may be hidden in three places: In such a situation, you first need to check the functionality of the fuse. It is located on the circuit board designated F5. You can check its working condition using a conventional tester. You also need to check the bimetallic fuse located in the purifier gearbox. If the wipers on a VAZ-2114 stop working in winter, there is most likely one reason - severe frost. The same fuse prevents the windshield wiper from turning on in case of overheating or freezing of the blades to the windshield.

Next, you need to check the relay (“short circuit” on the circuit board). You need to find it and temporarily replace it with a new breaker, and then check the operation of the wipers. If the windshield wiper does not function, we continue to look for the problem area. It is quite difficult to independently verify the operation of the switch. It consists of a complex structure, so it is easier to change it than to try to repair it. If the turn signal refuses to work together with the windshield wiper, the problem area is the switch located under the steering wheel.

MODERN WIPERS FOR VAZ 2114

To clean the windshield of a VAZ 2114 from dirt and water flows during rain, a special device is provided, so-called wipers on the VAZ 2114. VAZ wiper blades consist of a lever that turns in a certain direction and a rubber gasket that cleans the glass. The wiper gear motor causes the blades to move back and forth.

As a result, the windshield or rear window is cleaned. The windshield wiper speed control is located inside the car. It is almost always located under the steering wheel. The size of the brushes can be very different. Windshield wipers on almost all cars operate in several modes. On the windshield, the wiper functions in four ways:

1. intermittent, when there is a pause;
2. first speed;
3. second speed;
4. work together with the washer.

The rear window wiper has two modes:

1. without washer;
2. with washer.

How to remove the rear wiper?

To remove the wiper, you need to do two steps:

• remove the wiper itself from the top of the trunk lid;
• remove the wiper motor/gearbox from inside the trunk lid.

Next, we will consider these two stages in more detail.

Rear wiper removal process

We will need: keys for “10”, “24”; flat screwdriver.

1. First of all, use a flat screwdriver to lift the protective cover of the wiper arm mounting.
2. Using a “10” wrench, unscrew the fastening of the windshield wiper arm and remove the arm itself.
3. Next, using the same flat-head screwdriver, remove the black O-ring. (Pay attention to the condition of the O-ring: if it is cracked or burst, it needs to be replaced.
4. Then, using a “24” key, unscrew the nut that appears, securing the motor to the trunk lid. Remove the sealing rings. If the rings are damaged, they must be replaced. Damaged o-rings can cause water to penetrate into the gear motor, resulting in its failure.

Possible washer malfunctions

In order for the wipers to work properly, a constant supply of water is necessary. To automate this process, a washer was made. There may be the following reasons for its failure.

1. The steering column switch has failed. To check this, you need to close the two contacts located under the steering wheel. Front contact 53ah-w, rear contact 53ah-wh. After this, measure the resistance. In case of low resistance or breakdown, the switch must be replaced with a new one.
2. The washer pump does not supply water. It needs to be changed.
3. The wire connecting the switch to the pump has broken.
4. The injectors are clogged with dirt. They can be cleaned with a sharp needle.
5. Relay K3 does not work.
6. The hose broke.

As you can see, even simple parts have enough problems and breakdowns. However, following the operating rules will help avoid repairs and increase their service life.

Why the rear wiper of the VAZ 2114 does not work

Before going to the inspection, I discovered that the rear window wiper was not working. There is no noise and there is no movement of the wiper either, but the motor should work.

It is clear that since the rear window washer does not work, then three reasons may be to blame:

• Fuse
• Shift lever
• wiper motor

Since a new motor is not cheap, I decided to tinker with its repair myself.

First I checked the fuse. It turned out to be without damage or soot. Then I decided to check the steering column switch. Since all its other functions worked, except for turning on the rear wiper itself, I decided that it was working. It's time for the motor itself.

Windshield wiper trapezoids

The main reason you need to replace your windshield wiper arm is when your windshield wipers are running slowly. The trapezoid is also replaced in case of serious mechanical damage. To replace it, you must adhere to a certain technological sequence.

1. Under the hood, the wires connected to the fuse block are disconnected.
2. The protective casing covering the heater fan is removed.
3. The stove filter is removed.
4. The heater motor is disconnected. You just need to move it to the side, there is no need to remove it.
5. The decorative trim is removed from the wipers.
6. Under the protective rubber cover there is a nut that secures the windshield wiper. The cover lifts slightly and it unscrews. The janitor is removed.
7. The wiper shaft is freed from rings and gaskets.
8. The second windshield wiper is removed in the same way.
9. Under the hood, the bolts securing the trapezoid to the body are removed.

It will not be possible to immediately pull out the released trapezoid. The fuse box will interfere, as well as the heater motor. To remove the trapezoid, you can use two exits.

1. Remove the fuse box by unscrewing the nuts securing it, and remove the heater motor.
2. Disconnect the gear motor from the trapezoid. Remove the gear motor one by one, and then the trapezoid.

When disconnecting the gear motor from the trapezoid, it is necessary to remember and mark the location of the crank. A marker will be useful for this purpose. Only after this can you unscrew the mounting bolts and disconnect the motor from the trapezoid.

Windshield wiper repair

Since the system diagram is quite simple, repairing it at home will not be difficult. We will not describe the repair for a long time, since it can be performed without instructions, in particular, we are talking about replacing nozzles, hoses and a motor. In the case of a motor, when replacing it, you just need to disconnect the hose and remove it from the tank, replacing it with a new one. When installing a new pump, the contact surface with the tank should be treated with sealant to prevent the possibility of leakage.

We will dwell in detail on the repair of the trapezoid, since this part of the structure most often raises questions among owners of fours. As stated above, due to the inoperability of the trapezoid, the wiper blades will work slowly, so this element will need to be replaced. In principle, replacement is carried out in the event of mechanical damage to the device. In general, the replacement process is quite simple, but to perform the task correctly, you must follow the sequence of actions described below.

Possible washer malfunctions

In order for the wipers to work properly, a constant supply of water is necessary. To automate this process, a washer was made. There may be the following reasons for its failure.

• The steering column switch has failed. To check this, you need to close the two contacts located under the steering wheel. Front contact 53ah-w, rear contact 53ah-wh. After this, measure the resistance. In case of low resistance or breakdown, the switch must be replaced with a new one.
• The washer pump does not supply water. It needs to be changed.
• The wire connecting the switch to the pump has broken.
• The injectors are clogged with dirt. They can be cleaned with a sharp needle.
• Relay K3 does not work.
• The hose broke.

Causes of rear wiper malfunction

1. Steering column switch not working. It’s easy to check: turn on the rear wiper using the steering column switch and look at the voltage at + terminals 1 or 3 on the mounting block (see diagram). If there is no voltage, the steering column does not work . There is another option: we disassemble the steering column and check for a short circuit between contacts 53ah-53H. If there is a short circuit, then the steering column works .
2. Not working gear motor. Either replace or repair a non-working gear motor. A non-working gear motor means a malfunction of both the motor itself: commutator, brushes, fuse, etc., and its components: crank, teeth. How to replace the rear wiper gear motor?
3. The problem is in the wiring: either the wires going to the rear wiper gear motor have oxidized or broken. Particular attention should be paid to the weight of the gearmotor and its tightening. It would be better if you cleaned the mass again and attached it to another place. It is also possible that the wire may break at the junction between the roof and the trunk lid.

To check, it is better to check the presence of contact on the rear wiper block using a tester.

As for relay K3, it does not take any part in the operation of the rear wiper, which is a common mistake for beginners in car repair.

Mechanical contamination and damage

1. Freezing. Often problems with wipers begin during the off-season period, when there are frosts at night, and in the morning the air warms up to above-zero temperatures. You turn on the windshield wipers, not noticing that they are frozen to the glass. It seems like nothing is happening, but if you repeat this abuse of the motor regularly, the gears will fail and the motor will break.
2. Foreign objects. A falling stone or branch can damage the moving part of the mechanism because it creates resistance that the motor mechanism is not designed to withstand. If they then fall out while driving, you will not be able to understand why the wipers on the VAZ 2114 do not work well and what happened.
3. Damage to wires. The winding of old wires becomes brittle and can easily break. In this case, voltage losses in this area and a drop in the speed of the wipers are inevitable.

Wiper control

The wipers are controlled from a switch mounted on the steering column, which allows the wiper to operate in several modes, necessary in different weather conditions. The VAZ-2114 car has three types of wiper movement:

• intermittent mode;
• constant low speed of movement;
• constant high.

Often in VAZ cars the windshield wiper does not want to work in only one mode, so you need to know not only the design, but also the mechanism for controlling the glass cleaning system.

Intermittent mode begins to operate in the first and second positions of the switch. A relay located on the circuit board of the car and designated in the diagram as “Short circuit” is responsible for its operation. In the third position of the switch, the wipers operate in constant mode at a low speed. To switch the wiper to constant high-speed mode, you need to turn on the fourth position.
