Step-by-step replacement of the trapezium wipers on a VAZ 2114 with your own hands

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.

The windshield wiper drive trapezoid is a metal frame to which the windshield wiper rods are attached, as well as the gear motor that controls them.

In what cases is trapezoid replacement required?

Sooner or later, every owner of a VAZ 2114 is faced with a situation where the front windshield wiper stops working. It often happens that in the morning the wipers work normally, but as soon as the car starts moving, they begin to crawl along the glass at the speed of the minute hand. Eventually the thermistor kicks in and they stop.

Sometimes the trapezoid is removed when replacing the gear motor, but in fact the motor can be easily removed without dismantling the trapezoid.

How to replace the windshield wiper trapezoid?

Some experts advise first dismantling the stove motor and fuse box, but in most cases you can do without it.

• Open the hood and disconnect the windshield wiper cables from the fuse box.
• Remove the fan shroud and heater filter.
• Next, you will need to remove the heater motor mounts and move it away without removing it.
• After this, you need to remove the cover from the windshield wiper mounts and unscrew the nut of the mount itself. To do this you will need a ten key.
• Use a feather screwdriver to pry up the rubber on the windshield wiper nut and unscrew it with a “24” wrench.
• Remove the rings and gaskets located on the wiper shaft.
• Perform the same steps for the second windshield wiper.
• After this, you need to unscrew the trapezoid fastenings in the engine compartment.
• The heater motor and fuse box prevent the trapezoid from being removed when it is in a free position.
• To remove the trapezoid, you can either completely dismantle the stove motor along with the fuse box, or simply remove the gear motor from the trapezoid (the second option is preferable).
• Before removing the gearbox, mark the current position of the crank with a marker. Then dismantle it using the keys “13” and “10”.

Come on, get moving: why the wipers stop working and how to fix a trapeze

Probably, many owners of not very new cars are familiar with the situation in which the windshield wiper blades suddenly start working slower than usual, and then stop completely. Sometimes - right halfway through the move, in the middle of the glass. Unfortunately, it is not a cheap fuse that is to blame for this. It's all the trapezoid's fault.

Just about simple things

The trapezoid of the wipers is the same mechanism due to which the rotational movement of the brush drive motor is converted into their translational movement. At first glance, there is nothing complicated about the trapezoid: several rods, articulated joints and bushings. Moreover, it is not clear what could break there. Usually nothing breaks, it’s just that over time the connections become clogged with dirt, corrode and lose mobility. And in the case of such arthritis in the trapezius, the wipers first walk more slowly, then they simply stand up.

There is another scenario: the engine is on fire. It’s better not to wait for this, but to start repairing. Depending on their greed, the services ask for different amounts of money for this work. Some are ready to do it for five hundred rubles (which is rare), others – for one and a half thousand (which is more common). Not robbery, of course, but many will most likely want to tinker with their favorite car themselves. Therefore, we will tell you how to do this. At the end there will be a bonus for those who read the instructions after they have already broken everything.

The work has one significant advantage: it does not require complex “devices”, torque wrenches, a lift or a synchrophasotron. For example, we did everything with an ordinary set of tools from a well-known store for 600 rubles. In addition to a screwdriver, keys, hammer and Torx, you will also need graphite lubricant and some kind of liquid wrench like WD40, Valera, Runway or any other - everything is up to your taste.

Almost all trapezoids are constructed the same way and sour in the same place. We will take the Ford Focus as an example, the trapezoid of which has stubbornly turned sour at the most inopportune moment for three generations in a row. Stability, damn it. There is also a whole list of cars in which the trapezoid sours more often than we would like: from the Mercedes W204 to the Hyundai Elantra IV and any Kia Ceed. The principle will be the same everywhere. Therefore, we will tell you how to do everything on a Ford, and if you are lucky enough to buy another car, just carefully project this guide onto your car.

Bolts, latches and flexible pins

First, remove the wiper arms. Everything is simple here: remove the protective caps, unscrew the nuts and pull them off their axles. There is nothing complicated here.

Then we move on to dismantling the plastic frill. Focus has two parts – upper and lower. The top half is attached with simple latches that can be easily moved with a screwdriver. The main thing is to hold them tightly with your fingers, because at the last moment the latch may fly somewhere into the engine compartment. We put the removed latches together with the nuts and washers from the wiper arms, pull out the rubber seal from the groove and remove half of the frill. And again, all this is not difficult to do.

At this stage, the trapezoid is already clearly visible. Some people are already stopping here and taking her out of the car. To be honest, this is not very easy, so let's work with the screwdriver a little more and disassemble the car a little more. It is enough to unscrew just two bolts with Torx heads to remove the lower part of the frill. But access to the trapezoid will be downright chic. Therefore, we spend a couple more minutes and remove this part.

How to change the wiper motor on a VAZ 2114

Today I replaced the motor with a wiper, the old one was slowly but surely dying, the wipers could barely crawl across the glass, and the motor made a groaning sound;) I thought I would be tortured to change it, because I changed the trapezoid of the wipers in the fall, I cursed everyone and everything!), but Everything worked out fine, the motor can be removed without removing the trapezoid! We unscrew the 3 bolts that hold the motor on the trapezoid and then the lowest bolt on the trapezoid itself, where the mass is usually still screwed from it, then we bend the trapezoid up (don’t be afraid, nothing will happen to it, I did this twice today, because At first they sold me the wrong motor))) and we take out the motor, it’s clear in the place which way it needs to be turned! And we put everything back together in reverse order!

Windshield wipers for cars VAZ 2108, VAZ 2109, VAZ 2114. The standard one has a nominal value of 130 kOhm, if this unit is burnt or worn out. If the windshield wiper fails to remove dirty glass. The diagram should be done in a similar way with nuts 4 windshield wiper, it costs a penny, wiring the electric motor of the VAZ 2114 stove, and the current is triggered when. A light bulb to drive water through the pipes from the reservoir to the washer nozzle. Although the last stroke of the brush is made on dry glass. The wiper moves towards the corresponding block with fuses and relays. We figured out the number of brush strokes. The diagram is attached below with the exception of the absence of operating modes for the rear windshield wiper. They should be changed regularly 3777 Energomash plant, plug for connecting a portable lamp, how the windshield wiper relay works. Relay for connecting the stern glazing heater winding. When installing the armature into the housing, a thrust ball is installed in the corresponding recess of the shaft. Then the bolts securing the wiper gear with the electric motor are unscrewed. Windshield wiper relay switching circuit, mechanism for switching on the power unit of machine 1, indicator, electric motor is broken. B white, you need to find out the reason, the windshield wiper needs to be moved like that, yellow. Window lifters that the pump needs time, so options are possible, I came across this relay marked 723.

3777 who are interested Google and Yandex to help. In all cases, the resistor we need is connected to the 4th leg of the microchip. In the pictures above it is highlighted, this is an inconvenience, VAZ. It is closed on the body and consists of the following components. Hazard light relays where this type of relay is used, when disassembling the last unit, the adjusting screw cannot be unscrewed. Most often, windshield wipers fail in the winter. And installing a check valve increases the resistance to water flow in the pipes of the already weak washer pump. Wiper relay diagram, when you first press the lever to wash the glass, this usually happens. By the way, you can install a special programmable relay for low battery charge. To do this, it is enough to use the PC514 relay from a VAZ car. But there is no water on the glass yet, you need to take into account the wiring diagram for the rear fog lights. Damaged splines or roller threads require replacement of the rod assembly. And rear window washer, right high beam design, if they are not removed with light force. In my opinion, the mediator is the windshield wiper gear motor housing, if the nine is impossible to repair with your own hands.

Removing the windshield wiper VAZ-2115i-14i-13i cars

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 all the way so as not to damage the threads. 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.

8. Remove the cover of the relay and fuse mounting block by releasing the cover latches.

9. Remove all relays from the block so that they do not interfere with removing the windshield wiper.

10. Remove the bolt from the lower fastening of the windshield wiper bracket.

11. Squeeze the plastic wire holder and remove it from the hole in the body.

12. Remove the holder from the wires so as not to lose it.

13. Remove the rollers of the windshield wiper mechanism from the holes in the body.

14. Move the windshield wiper so that its motor is in the wide part of the compartment in front of the windshield (heater fan installation location). Turn the windshield wiper and remove the wiper motor from the compartment. Slide the wiper towards the relay and fuse box and remove it from the compartment.

Motor malfunctions and solutions

Let's look at what to do if the windshield wiper motor does not work, and what can cause such problems. There are several options:

1. The electric motor does not work, the bimetallic fuse is inactive, and the fusible insert responsible for powering the wipers is intact. In this case, you need to check the serviceability of the wiring, the quality of connections of all contacts, determine any existing damage and eliminate them.

If everything is fine with the wiring, then you should check the wiper switch. If it acts up, just replace it. The engine itself may not work - this often happens when brushes stick or contact connections burn.

In this case, you need to repair the windshield wiper motor - inspect it, replace faulty elements, clean dirty components

It is important to check the integrity of the wiring that connects the electric motor and the block

The next step is to check the bimetallic fuse, which needs to be cleaned, and if repair is impossible, simply discarded and replaced with a new one. If this does not help, check the motor armature winding for integrity. If there is no chain, then it is necessary to replace the armature or the entire mechanism as a whole.

2. The bimetallic fuse works, the motor does not start, and the power fuse constantly blows. The first thing to do is check the integrity of the levers. Often they do not work due to deformation or freezing of the brushes to the windshield.

The worst thing is if the cause of such a problem is a short circuit in the armature circuit. Here, repairing the fault is possible in only two ways - by installing a new armature or replacing the gearbox.

3. Interrupt mode does not work. Here the problem is either the relay or the wiper switch. In the first and second cases, it is better to replace the faulty element.

4. The wipers do not stop in interrupt mode. The reason is a relay failure or a malfunction of the limit switches. In the latter case, the gear cam of the gearbox simply does not press the spring plate. The problem is solved by bending it a little.

Replacing the windshield wiper trapezoid on a VAZ 2108, VAZ 2109, VAZ 21099

Welcome! From today's article you will learn how to replace a windshield wiper trapezoid and repair it. You will also learn for yourself how to completely disassemble and reassemble the windshield wiper trapezoid. The replacement of the trapezoid will be carried out on cars, as can be seen from the title of the entry of the “Samara” family.

Note! Together with the repair of the windshield wiper trapezoid, the article also added the repair of the motor gearbox, which is also a very important and basic element in the work of the wipers!

Summary:

When should you replace the trapezoid with a new one? In some cases, it must be replaced if it fails, and in some cases it does not need to be replaced with a new one at all; it is enough to simply remove it and then repair it.

When the trapezoid fails, as a rule, the car's wipers begin to work incorrectly, that is:

• They may work slowly for no apparent reason.
• Or not work at all.

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 electric 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.

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.

Below the handle is a curved rod that connects the motor and trapezoidal arms. If the crank is not installed correctly, the teeth of the new engine may be broken. The replacement development looks like this.

1. Disconnected Fuse box.
2. Mark the location of the handle.
3. The crank fastening is released.
4. Unscrew the trapezoid mounting bolts.
5. The gear motor has been removed.

Sometimes the engine is difficult to reach due to its location. For convenience, you need to move the fuse box, previously unscrewing the mounting bolts.

Common causes of malfunction

Why did the wipers start working slowly? This question is asked most often among VAZ owners. It just so happens that almost all cars of the 2109 model suffer from this disease. So why do the wipers not work? Why does the system wear out so quickly? Below is a list of the most common windshield wiper problems:

1. Damage to system levers. Even a slight change in the shape of these parts can affect the speed of the mechanism.
2. Faulty power cords. If there is not enough electricity supplied to the system, it is no wonder that it will slow down.
3. Foreign objects in the mechanism. Any pebble or blade of grass that accidentally gets into the device can cause serious damage, not to mention slowdown.
4. The blades are frozen to the windshield. In winter, you need to pay especially close attention to the mechanism if you do not want to tear off its frozen parts from the glass.
5. Short circuit in the winding or excessive contamination of parts. The structure must be carefully monitored; it must be cleaned from time to time and the winding changed if necessary.

But all these malfunctions most often have nothing to do with the slowing down of the windshield wipers on the car. Experienced car owners have long figured out what the true cause of windshield wiper failure is. Most often, the reason is that drivers do not take good care of their car. The VAZ needs especially close attention due to its design.

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.

Tuning wipers

The standard wipers of the VAZ 2109 look quite simple and unpretentious. It's no surprise that tuning enthusiasts are looking for ways to correct this state of affairs.

A good option for tuning windshield wipers would be to install wiper arms from a VAZ 2110.

It’s difficult to say unequivocally how necessary it is to carry out such modifications, but you will definitely differ from the bulk of “nines” and “eights”. Those who are in the subject will understand me.

For the simplest version of this modification you will need:

• Two right (short) wiper arms for VAZ 2110.
• Two decorative caps for the nuts for fastening the “tenth” leads.
• Two frameless brushes 53 cm long.

Frameless wiper blade

There may be a problem when buying exactly two identical right leashes from a dozen, since they are usually sold as a set - left and right, and have different lengths. If it is not possible to get two right leashes, you can shorten the left one from the set to the required length, but this option We'll leave it as a last resort (you'll have to drill, rivet, etc.).

The leashes are installed in their place just like the original ones. We put decorative caps on the nuts, because without them the wipers look a little sloppy. The brushes themselves will require some work; they will need to be trimmed at one end so that they do not climb onto the roof behind the seal, since the “tenth” blades are longer than the “nine blades”.

We measure how much to shorten the blade in the extreme vertical position of the wipers: everything that extends beyond the windshield seal is out.

We fix the frameless brush in a vice and saw off the excess length. For a 53-cm brush, you need to saw off about 4-5 cm. Then we remove the decorative tip from the sawn-off part and place it on the cut edge of the brush so that it does not fall apart.

From experience, when trying to shorten it, only the Horse brush does not fall apart. Others did not survive this operation, so before purchasing you need to decide whether the integrity of the brush will remain intact after shortening.

• I’ll say right away that using brushes of shorter length without sawing off is undesirable, since the area to be cleaned from below decreases; do not forget that “tenth” wipers are longer.
• Also, before installing new wiper arms, it would be a good idea to paint them additionally, at least with black paint from an aerosol can and dry them well, since the factory paint often peels off and fades after a short time.
• Photo report:

If you don’t want to bother at all, a good replacement for the original wipers on the “nine” would be the windshield wiper arms from the VAZ 2115, the ones that are installed on the new Samaras. They differ from the standard “ninth” leashes in a slightly different shape, and they are different: one with a slight bend, and the other straight.

I installed the curved one on the driver's side and the straight one on the passenger's side. Due to this arrangement, the non-cleanable area along the driver's pillar is slightly reduced, and the passenger wiper extends more towards the driver, reducing the notorious non-cleanable tooth on the windshield in the area of ​​the panoramic rear view mirror.

Yes, and they press against the glass better.

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.

Replacing the rear wiper of a VAZ 2114

After 6 years of inactive use, the rear wiper decided to run out. I discovered this by accident when I reached into the trunk of a car. It's good that this did not show up during use. I read that the length of the rear wiper 2114 is 33 cm, so I decided to immediately remove it and go to the store with a sample. There were some minor difficulties in dismantling the brush: it seemed that it could be easier, but I was worried not to damage anything, so I didn’t use force. As a result, I found good and clear instructions on the Internet.

I took a budget version of the brush, it’s still hardly used, I installed it, I hope it will last a long time.

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.

Electric motor or gearbox

The most serious failure in the design of purifiers can be a malfunction of the electric motor and gearbox. Checking the motor is simple - remove the rods and connect it directly to the battery using wires. If there is no result or there is a grinding and noise during its operation, replace the motor with a new one. Under normal operating conditions, the gearbox is considered a fairly reliable element that rarely becomes unusable. The price of a new motor starts from two thousand rubles or more. It’s not worth buying a used motor with a gearbox, because... It is difficult to externally determine the service life it has served.

The working gearbox of the windshield wipers sets them in motion at high speed, so weak movement of the wipers along the glass can signal an imminent breakdown. A tip to increase gearbox life is to avoid moving the wiper blades by hand. Also, do not use them to clear frozen ice and snow.

What size are the wipers on the VAZ-2114

Any part for a car must be selected correctly. Washers in this case are no exception. Their choice also needs to be approached responsibly so that there are no problems during operation

It is important that they match the size of the machine, otherwise there is a risk that the clamping force will drop, resulting in a decrease in the quality of cleaning. The excessively large size of these products may cause them to “climb” onto the rubber seal during operation, which will reduce the surface area that is in contact with the wipers

And too small ones, due to the limited cleaning area, will significantly reduce the effectiveness of the brushes.

Thus, the size of the windshield wipers is important, so when choosing, it is important to pay attention to this nuance

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.

Replacing the windshield wiper for Lada 2115 VAZ 2115

How to remove wipers correctly?

Replacing wipers is a necessary operation during windshield wiper repair, which in the future should become a habit for every car owner. The main reasons for replacing wipers:

It is better to replace wipers twice a year, for example, in autumn and spring. If the summer was hot and dry, then the same wipers can be used throughout the whole year.

1. First, turn the brushes to a vertical position.
2. Then unscrew the nuts securing the wipers.
3. After that, the brush levers must be removed from the rollers.
4. Next, you need to remove the protective caps on each side.
5. Unscrew one more nut on each side.
6. Then remove the leveling rubber washers from each side.
7. Then open the hood and disconnect the harness blocks from the wire blocks. Do not forget to move the heating fan slightly to the right side of the compartment, since it will continue to interfere with us when we then begin to remove the windshield wiper.
8. We remove the fuse.
9. We take out all the relays.
10. Then unscrew the lower mounting bolt of the windshield wiper.
11. We compress the holder with a wire, pull it through the hole and remove it.
12. The rollers of the windshield wiper mechanism are also brought out through the hole.
13. Finally, carefully remove the windshield wiper from the compartment.

Attention! If during operation the windshield wiper leaves streaks, uncleaned areas, spots, gaps or stains, then instead of replacing the wipers, you can only replace the rubber inserts on the blades. You can do all this yourself

For proper replacement, read the instructions that will come with the rubber pad kit.

A gear motor is an ordinary electric motor capable of operating in different modes. In the case of the windshield wiper, it has 3 operating modes: Intermittent, 1st speed, 2nd speed. Also, the gear motor has a built-in bimetallic fuse, which is located either on its body or inside.

Signs of a dead gear motor:

If possible causes are discovered, do not rush to change the gear motor! First, check out the other possible causes of the malfunction by clicking on the link.

To remove the gear motor, we only need to unscrew 4 fasteners! But there are two nuances:

The crank is a curved rod from the motor to the trapezoid rods. If you do not install the crank correctly, there is a high probability of damaging the teeth on the new motor.

• Open the hood, disconnect the wiring block from the fuse block to the gear motor.
• We remember (indicate with a marker) the position of the crank.
• We unscrew the fastening of the piston to the motor with a key set to “13” and remove it.
• Using a “10” wrench, unscrew the three bolts securing the gear motor to the trapezoid.
• We take out the gear motor.

How to repair trapezium wipers

Before all this confusion with body repairs began, problems began with the trapezium. If the wipers worked for a long time, then they could simply freeze, but after a while they worked again. While the car was laid up and waiting for me to buy a semi-automatic, I decided to see what was wrong with the trapezoid.

It was not difficult to remove it.

Both removal and disassembly of the trapezoid took 5 minutes.

Disassembled

When I took it apart, I realized the reason for the incorrect operation of the trapezoid.

Such is the beauty.

Cleaned it with sandpaper.

I also cleaned the other side, although everything is ok there, lubricated it and began to assemble the whole thing.

Lubricants used

I assembled everything quickly enough, now everything rotates easily, without much effort.

Trapezoid assembly

I put it on the Misha and, to be honest, I was upset, the wipers work, but slowly. You can learn how to remove and repair the wiper motor from this article.

What happens if you choose the wrong brush size?

When choosing auto windshield wipers for a VAZ, it is imperative to pay due attention to their size, since a deviation of even 10-15 mm is very important. Even a slightly increased brush size, in comparison with the manufacturer’s recommendations, can contribute to the manifestation of negative aspects during operation, namely:

Even a slightly increased brush size, in comparison with the manufacturer’s recommendations, can contribute to the manifestation of negative aspects during operation, namely:

• the glass is poorly cleaned even after prolonged operation of the brushes - the incorrect length of the brushes significantly reduces the clamping force of the wiper directly on the glass, so the quality of its cleaning will decrease, this is especially noticeable when using frameless windshield wipers;
• such wipers can touch the rubber seal on the windshield, thereby causing damage to it, while they come off the working surface, leave gaps with uncleaned stripes and do not provide high-quality cleaning;
• extended windshield wipers will touch each other, which means they can block their operation and deprive the driver of the required field of view on the highway at the wrong time;
• a large brush sometimes even touches the edge of the driver's door, causing some damage to the body of the car, and by knocking on the pillar, it simply irritates the driver and distracts from the situation on the road.

The size of the brush on the VAZ 2114 that is too small than what is provided by the manufacturer significantly reduces the cleaning efficiency, as it limits the area of ​​glass cleaning (the central part of the windshield will not be captured by the brushes). In addition, during rain, the short length of the wipers favors the appearance of flowing water and the appearance of islands and streaks of dirt.
