✅ How to check the wiper relay on a VAZ 2110

Device

General structure of the windshield wiper system:

As everyone knows, the wipers are driven into a state of “swinging” of varying speeds by an electric motor, which has a built-in gearbox, and the motor runs on direct current. Three brushes are “built-in” in the motor armature, with the help of which the VAZ 2110 wipers operate in three modes. There are only two speed frequencies: one for fast movement (for example, during a rainstorm), the second for slow or intermittent movement;
The electrical component is the switch (under the steering wheel); relay switching on intermittent mode; additional relay; switch. The entire electrical system is connected by wires (in blocks) through a thermal bimetallic fuse. Moreover, both one and the other relay, as well as fuse F5, are located in the mounting part, and a bimetallic fuse with a limit switch is located in the electric motor gearbox;
Directly windshield wipers. Their size is important, as well as the material, shape, and device. Check whether the already installed ones squeak, whether the mechanism and the leash are working, perhaps they need improvement;
Mechanics. First of all, this is a drive that can break.

The wipers do not work, the sound of the motor is not heard

Most likely, the problem should be looked for in the gearmotor itself. To check the electric motor that drives the windshield wipers, it must be removed. First you need to check the fuse on the motor itself (it can be either directly in the gear motor or somewhere near it). You should try to connect the removed wiper motor directly from the battery: if the motor does not come to life, then the problem lies with it. Moreover, most often the motor does not require replacement: it can be overhauled by replacing the brushes or lubricating the entire mechanism. If the motor is working properly, the reason may also be in the steering column switch or in the wiring. You can check the serviceability of the steering column switch using a tester: disconnect the wiper wiring block and connect a tester to check the presence of voltage when switching wiper operating modes.

Causes of malfunction

Therefore, if the brushes are completely frozen, or only squeak, the root cause should be sought in the electric motor. Not forgetting that in addition to electrical problems, there may be mechanical problems.

The most common ones are:

When you turn on the windshield wiper, you can hear the motor running, but it only jerks or remains motionless. First of all, you need to suspect that the nut securing the crank to the gearbox axle has become unscrewed or loosened;
If the windshield wipers operate but are not synchronized, the leash may be the culprit. Most likely, the nut securing it has become loose. Before tightening it, you need to put the wipers in the correct position.

If the electrical part is faulty, the symptoms will be:

The wipers work slowly, stop wherever they want, and do not want to take the lower position. The limit switch may be to blame for this. Its adjustment consists of bending the contacts. If such repairs do not help, then the entire electric motor assembly needs to be replaced, since it is sold only together with the gearbox;
Intermittent mode is turned on, but the brushes work without stopping. Most likely the relay has failed and needs to be replaced. This is definitely a relay if on a VAZ, when the intermittent mode is on, the noise of the rotating armature of the wiper motor is inaudible. But if the replacement did not help, the contacts of the limit switch may have oxidized or burnt;
You turn on any of the modes, and you only hear the thermometallic fuse click. The brushes “stand still” and the anchor is also inaudible. First of all, check to see if the brushes are frozen and therefore do not move. By the way, fuse F5 often blows in this case. Another possible reason is that the anchor burned out;
The electric motor does not work, although both fuses are intact. It is necessary to check all the contacts that the drive has, as well as the motor. Perhaps the brushes are stuck or the armature is burnt out.

How to check the wiper relay on a VAZ 2110

Hello.
Yesterday the intermittent wipers stopped working. I wanted to brush the snow off the glass (I’ve done this a hundred times), but they twitched a little and that’s all. When you spray on the glass, the wipers are also silent. The relay clicks. Fast and slow work, but when turned off they stop where they turned off, without returning to their original position. Where should I look? There was a relay that clicked, but it didn’t work either, the contact group in it was burnt out. it worked once.

at the same time, what it is and what it is not. without it, the wipers only move in the third position. You can unhook it altogether and check how it goes

There was such a thing. I drove in heavy rain and the wipers failed. Only the fastest mode worked.

I also thought about the relay (the relay also clicked) and the motor. I bought this relay and installed it. but there's no point. I was already planning to buy a new windshield wiper, but I decided to check the contacts first. Is current supplied to the motor?

It turned out everything was banal. The terminals oxidized a little and the contact was lost. I took everything apart, cleaned it and lubricated it. work fine! Hemorrhoids are only full with analysis of Shumka and toad

Repair

Having skillful hands and basic knowledge of how the wiper mechanism works, there is no need to contact a paid service to make repairs or change windshield wipers. Replacing the windshield wiper motor on a VAZ 2110 is also quite simple.

Parsing is carried out in this way:

Remove the dashboard;
On the left we find a relay screwed to the body. If the relay turns out to be faulty, then repair is unlikely to help it; a replacement is needed;
We check the fuse responsible for the wiper drive;
We disassemble the steering column to inspect the switch. If it turns out that the switch has insulation damage or other problems, it means it needs to be replaced;

We unscrew the motor from the body and check for functionality. If there is a minor problem, it can be repaired, or perhaps it will need to be replaced, along with the relay. There is no point in repairing the relay separately - its cost is cheap;
Inspect the drive; one of the possible faults is that its pulley has broken.

Windshield wiper repair

In practice, repairing wipers on a VAZ 2110 is not at all difficult if you have at least basic experience in working with a car and its electrical components.

Unscrew the fixing nut

First, let's figure out how to remove the wipers on a VAZ 2110. The design provides several fasteners, by unscrewing which you can easily remove the wipers themselves.

But with disassembling the windshield wiper assembly, everything is a little more complicated. It is analyzed as follows.

Remove the dashboard.
On the left side, find the relay that is attached to the body. If it is broken, there is no point in repairing it. Just install a new relay.
Next, check the condition of the fuse that controls the operation of the windshield wiper drive.
Disassemble the steering column to allow you to examine the state of the switch. If the insulation is damaged or there is other damage, replace the unit.
Unscrew the electric motor from the body and check it in action. If the damage is not serious, it can be repaired. It's better to immediately replace it along with the relay.
Check the drive. It is not uncommon for a pulley to break on it, which is why the device has to be replaced with a new one.
Make sure the trapezoid is in good condition. It may be necessary to replace the windshield wiper trapezium on a VAZ 2110 if, during operation of the car, the lubrication of the device has deteriorated and all kinds of debris and water have gotten in there. If the lubrication does not work properly, the plastic bushings of the hinges wear out, causing play and increasing resistance during operation of the device. The trapezoid itself serves to transmit force from the electric motor to the windshield wiper arms.

Alternative

When choosing wipers, not only their size matters, but also the device, as well as the manufacturer. For VAZ 2110 of all years of manufacture there is one size for the wiper on the driver or passenger side - 20″ (wiper length 508 mm).

However, you should know that you can usually increase the size to 53 cm, but no more, otherwise the windshield wipers will not cope with the task assigned to them, and the drive may fail, because the leash is not designed for such a load. In addition, such wipers creak during operation and can operate jerkily.

If the size is chosen incorrectly, the mechanism will fail faster. In principle, many people use the “original” VAZ wipers and are satisfied with them. But it is possible to modify windshield wipers from other companies, often of higher quality.

For example, for many, frameless brushes (especially Boshevsky ones) are very attractive. They are compact and have a special leash mechanism. However, they do not look particularly nice on a VAZ, since their fastening to the arm of a regular frame wiper turns out to be massive. These brushes need some work.

This material will help you figure out why your car windows sweat: https://vazweb.ru/desyatka/salon/poteyut-stekla.html

The VAZ 2112/2111 model has a rear wiper, its size is 11″ (27.9 cm).

Both regular replacement and modification of wipers begin with disconnecting the negative terminal of the battery. Then you need to pull the wiper towards you and remove the brushes.

If there is a decorative trim, it should be removed. Unscrew the bolt and remove the old wiper. Be sure to compare the size of the new windshield wiper with the old one. It will be better if the size of the windshield wiper on the VAZ 2110 does not exceed its predecessor by more than 2 cm. Install everything in the reverse order.

Relay Test Tool

So, how and how to check the serviceability of a car relay or any other? You will need a regular multimeter, also known as a tester.

There are two main types of multimeters on sale:

Analog or pointer. Everyone remembers it from school physics lessons: a semicircular scale with an arrow. You can use them only if you don’t have a digital one at hand. Their accuracy, especially the new one, leaves much to be desired, even down to the reading of random variables. The only exceptions are old Soviet multimeters, which still work well today.

Digital. Sold at any tool and radio parts store. Even a budget D830 is suitable for work - its accuracy is quite enough. Although more expensive testers have automatic range detection, which is convenient.

Similarly, you can use a combination tool, such as a current clamp with a built-in multimeter.

Please note that in order to ring a relay, the dialing function itself is needed.

On the device it is indicated as follows:

First stage: diagnostics and elimination of electrical faults

Every owner of the tenth model probably noticed clicks and noise coming from the gearmotor located on the left when activating the windshield wiper system. Therefore, at the initial stage of solving the question of why the wipers do not work on the VAZ 2110, you should pay attention specifically to the nature of the operation of this unit.

The electric motor does not show any signs of operability - it is necessary to inspect fuse F5 in the mounting block located on the left under the headlight beam hydraulic corrector. A serviceable fuse primarily serves as an indicator of problems in the electric drive feeding system.

A multimeter will help you identify the faulty area: you need to “ring” the circuit in resistance mode from the fuse to the gearmotor and steering column lever, and even the switch itself. The multimeter induces zero: the section is serviceable, an infinitely large value is a reason to inspect the terminals and wires.

The malfunction is resolved by the following steps:

clean/crimp the terminals in the fuse block, contact connectors of the steering column switch and gearmotor;
replace wires;
replace the lever on the steering column that activates the windshield wipers.

Relay K2 type 524.3747, located in the mounting block, is responsible for the operation of the windshield wipers in cycles with pauses (I and II positions). The system does not operate in intermittent mode - a reason for a detailed inspection and replacement of the relay. Under such circumstances, the steering column switch should also be “sinned”.

Testing contact groups

Finally, it wouldn’t hurt to call the contact group. Understanding what a relay is for, it becomes clear that it is an electromechanical switch. When current is applied, it closes two contacts and transmits the current further. It looks like this.

It can be understood that in the open position, when no current is supplied to the relay, the contacts should not short-circuit with each other in principle. When electricity flows in reverse, the pads are connected to each other. This is what the diode continuity reflects.

Touch the pair with the probes. They need to be installed in the same way as before.
Without voltage supply, the tester should not make sounds in dialing mode.
Then apply voltage and look at the device. Firstly, a characteristic loud squeak should appear. Secondly, numbers flash on the screen.

Be aware that beepers may break. Therefore, before ringing the five-pin relay, check them. You can simply touch the tip of the screwdriver with the probes or short-circuit them.

Please note that the instructions are universal for all types of relays: turns, wipers, main unit.

Mechanical faults

mechanics Often the wipers on a VAZ 2110 car do not work due to a banal loosening of the nut that presses the brush holder to the trapezoid shaft.
You can restore the system's functionality instantly by adjusting the angle of the brush and tightening the lever with a nut. An unscrewed nut that facilitates the transmission of torque from the gearbox to the trapezoid can be reported by one of two events:

the electric motor remains operational in all modes, but both brushes do not move;
the brushes spontaneously stop working in an intermediate position.

However, stopping of the brush holders in an arbitrary position can occur due to poor pressing of the “limit switch” contacts to the gear motor gear or oxidation/burning of the same contacts. And the brushes are not able to move even after chipping the teeth of the gears, which do not have a long service life - after all, they are made of plastic.

Checking and removing the windshield wiper motor VAZ-2109

An element such as the motor responsible for operating the windshield wipers on a VAZ-2109 car does not fail very often, but if this does happen, it must be replaced with a new one.

This is not very difficult to do, but the procedure itself takes a lot of time, especially for those motorists who do not have the proper experience.

First of all, it is necessary to de-energize the system. To do this, simply disconnect the negative terminal on the battery.

Place the windshield wiper arms in a vertical position;
Unscrew the nuts and remove them from the rollers;
Remove the protective caps;
Tighten the nuts (on one side), mounting brackets on top;
Remove the rubber sealing washers;
In the engine compartment, the wiring harness has been removed from the connector;
Remove the bolts holding the bottom of the bracket;
The mechanism rollers are removed from the holes;
Unscrew the nut that secures the windshield wiper crank and remove it;
Remove the bolts holding the wiper blade and motor in place;
Disconnect the wires from the bimetallic fuse and remove the motor from the bracket.

All that remains is to remove the retaining ring and shims from the gearbox shaft and install the new motor. Reassemble in reverse order.

For more comfortable operation, we recommend moving the oven fan to the right. Without this, the wiper cannot be removed. You will also need to remove the fuse cover and any relays that are there.

The wiper itself must also be moved slightly to the left before removal.

Total

Windshield wiper failure can occur for quite trivial reasons:

fuse F5 burned out;
the terminals of the connecting blocks are oxidized or burnt;
wires are faulty;
relay K5 524.3747 broke;
ordered the steering column switch to “live for a long time”;
the nut that attracts the trapezoid crank to the gearbox has become loose;
the nuts securing the levers to the trapezoid shafts were unscrewed;
The brushes are frozen to the glass.

Often, wipers on models of the VAZ 2110 family do not work due to complex faults:

oxidation/burning, insufficient pressing force of the contacts of the limit switch located on the gearbox cover;
brushes hanging in the gearmotor;
burnout/contamination of the collector;
break in the armature winding;
chipping of gear teeth in the gearbox.

VAZ 2109 wipers: examination and rehabilitation techniques

The “nine” has a classic windshield wiper circuit: the steering column switch via a relay (intermittent modes) or directly supplies power to the electric motor, which causes the gearbox - crank - trapezoid - brush holders to rotate. Long-term practice demonstrates that

wipers If suddenly the wipers on your car stop working, this is not a reason to panic. This device is quite simple and, if desired, anyone can independently eliminate the cause of the malfunction by following the further instructions. And so, let's find out why the wipers on your VAZ-2105 do not work.

How to detect and fix problems in the windshield wiper system of a Lada Kalina car

The design of the windshield wiper system is a fairly simple diagram. If desired, any car owner is able to understand the cause of the malfunction and fix it independently.

Repair of windshield wipers on a VAZ 2109 car

Wipers are a very important part of a car's equipment. Their functions are especially useful in the autumn-winter period.

Troubleshooting Methods

If the wipers do not work on the VAZ 2109, then you can detect and repair the damage yourself.

The repair is carried out in stages:

The assembly is first disassembled;
Then faults are detected;
Then repair or replace the faulty parts;
At the final stage of assembly.

Disassembling the windshield wiper

Disassembly consists of the following sequence of actions:

First of all, you need to turn off the power to the car by removing the negative terminal from the battery.
Next, the brush arms are installed in a vertical position, then the fastening nuts are unscrewed. Now you can remove them.
Using pliers, carefully pull the levers out of the slot without damaging the threads.
The plastic protective caps are removed from the socket.
Then you need to unscrew the bracket mounting nuts and you can remove them along with the washers underneath them.
Next, in the engine compartment, you need to disconnect the electrical wiring that is used to power the windshield wiper motor.
The next step is to move the heater fan so that it does not interfere with the removal of the mechanism. To do this, unscrew the screws.
We remove the cover from the mounting block and dismantle all the relays located in it, as they will interfere with further work.
Unscrew the lower bolt securing the wiper arm.
Then slide the plastic wire holder through the slot on the back panel and remove it so you don't lose it.
Through the holes in the case we show the rollers of the device. Then, by slightly lifting and sliding the windshield wiper and motor up and to the side, remove the assembly.

Further. Complete disassembly of the mechanism. Visual inspection of all parts, including the wipers of the VAZ 2109. A broken brush can be replaced, but it is better to replace both. If mechanical damage is detected or parts are severely worn, they must be replaced.

Once all faults have been identified and corrected, we reassemble the assembly in reverse order and install it in its usual location. After the repair, you need to connect the negative terminal on the battery and check the operation of the windshield wiper.

Finding Electrical Problems

Each owner of a VAZ-2110 involuntarily paid attention to the clicks coming from the left side and the barely audible noise from the gearmotor when the windshield wiper was running. Therefore, at the initial stage of searching for the reasons why the VAZ-2110 wipers do not work, you need to check the performance of this particular product.

If the electric motor does not show any signs of life, you need to check the fuse located on the mounting block, which is located on the left side, under the headlight switch lever. If the fuse is in working order, this indicates a malfunction in the electric drive feeding system.

A multimeter will help determine the problem area in the circuit. You need to check the circuit from the fuse to the gearmotor, from it to the hydraulic corrector.

Naturally, it is necessary to check the fuse itself. If zero is constantly lit on the multimeter screen and a not very pleasant sound signal is heard, then the circuit is working properly. When several numbers appear on the screen, without sound, we move on - we move on to inspecting the terminals and wires.

You can troubleshoot the problem as follows:

Clean and tighten all terminals that were checked with a multimeter.
Replace wiring.
Install a new lever on the steering column that turns on the windshield wiper.

Relay K2 (5243747), located in the mounting block, is responsible for the operation of the windshield wiper. If an intermittent mode is not observed during system operation, then it is time to change the relay. Under these circumstances, the hydraulic corrector also needs to be checked. If the windshield wiper relay has a defect, it will work wonderfully in the third extreme position of the right steering column stalk. A faulty relay does not stop working in all cases. Windshield wipers can function perfectly if they are turned on in position 1, but the fact that there is a defect and the relay is not working correctly will be indicated by pauses between sweeps of the blades. Often the relay simply goes away, and the wipers and heater do not work at the same time. In this case, you usually need to tighten the contacts.

Power supply

The main and auxiliary relays make clicks during operation - this indicates its full functionality. The power couple is responsible for this, which also needs to be checked.

One of the contacts is always energized, while the second receives electricity only when it is on.

You can check them using a voltmeter. It is also included in the tester and is designated by the symbol “V”. Set the switch to constant voltage mode.

Electromechanical problems

An electric motor that shows no signs of life, no click and a blown fuse F5 - all these problems indicate faults in the gearmotor, which can be eliminated by replacing one of the components:

dirty collector in the electric motor rotor;
brushes that ensure continuous contact in the motor;
burnt collector;
broken armature winding.

There are other options: the electric motor does not want to work, but there is a click, or the fuse blows. In this case, you need to return the left lever to its base position as quickly as possible, since these problems indicate a short circuit in the electric motor. It needs to be completely changed. With the same problems, there may be minor faults: brushes frozen to the glass, or wipers touching body parts. Under such circumstances, you need to carefully separate the brushes or straighten their mounting arms.

Engine repair

Many people think that replacing the engine with a similar one in a foreign car can solve the problem of slow wiper operation, but in fact, cleaning and lubricating the “original” engine is quite simple.

READ VAZ 2108 All Wheel Drive Do It Yourself

If the grip is causing speed, you need to check how easily the armature rotates: if movement is difficult, damage to the brushes or excessive wear on the brushes should be suspected. They are easy to exchange for new ones.

Cleaning the manifold will also help. You will need fine sandpaper. The need for this procedure is said:

Visible contamination;
Noticeable scratches;
Grooves on the metal.

It is necessary to replace the valve or transmission with the engine running if the manifold is too worn or burnt out.

Adjusting the speed is necessary if the wipers are running too slowly. This contributes to:

Incorrect (too “dense”) lubrication;
Gear wear;
Traction deformation.

Eliminating these problems basically makes the wipers work faster and, in addition, significantly.

Mechanical problems

Often the windshield wiper on a VAZ-2110 may not work due to a loose nut pressing the blade holder. This fault can be repaired in a few seconds. It is enough to tighten a poorly tightened nut to restore the functionality of the wipers. Some events may indicate an unscrewed nut:

When the electric motor is running, the brushes do not move.
The brushes stop working on their own in an intermediate position.

Also, brush holders may stop due to poor contact pressure in the gearmotor. If the teeth on the gearmotor gear are crumbled, the brushes will also not work.

Wipers do not work on VAZ 2110 - reasons and repairs

An indispensable attribute of the VAZ 2110, like any other car, is windshield wipers. Their colloquial name is “windshield wipers”. Their purpose is to clean the glass from water stains and dirt in case of bad weather. Of course, the work of wipers is most often necessary in the off-season, when there is the most rainfall. During these periods, without properly functioning windshield wipers, driving a car is not only difficult, but dangerous.

Like any other important component of the VAZ 2110, the wipers need regular inspection and, if necessary, repair. This usually happens once every five years. But you may have to start repairing your windshield wipers earlier - if they start working slowly or don’t work at all.

Repairing windshield wipers is not difficult; any self-respecting car enthusiast is quite capable of doing it himself. Below we will look at algorithms for repairing wipers on a VAZ 2110, and even how to completely replace them correctly.

But let's start by considering all the elements that ensure the operation of the windshield wiper:

Electrical part

It includes:

The electric motor of the windshield wiper itself;
Windshield washer motor;
The windshield wiper and washer switch is located under the steering wheel of the VAZ 2110;
The main and additional relays are located in the mounting block and provide cyclic operation of the wipers;
Bimetallic fuse is thermal in type; its limit switch is located in the gearbox of the windshield wiper motor.

Mechanical part

It includes:

The brushes themselves - their working part is made of rubber and is subject to fairly rapid wear;
A trapezoid is a structure made of metal guides; they ensure the conversion of the rotation of the electric motor into the actual operation of the wipers. The trapezoid is subject to deformation and clogging of the joints.

Accordingly, from the structure of the windshield wiper assembly, it follows that all breakdowns belong to two groups:

Mechanical;
Electrical.

Consider mechanical breakdowns

If, after turning on the wipers, their electric motor is clearly working, but the wipers themselves do not move or twitch convulsively, then the reason for this is the loosening of the nut securing the trapezoid crank of the wipers to the axis of the electric motor gearbox. Sometimes this nut does not just loosen, but is completely twisted.

The wipers work, but the synchronization and smoothness of their movements are disrupted. In this case, the cause of the breakdown is the so-called “leash”. The nut holding it in place loosens.

Both of the considered breakdowns can be corrected by simply tightening the nut securing the wiper units. Of course, before this you need to put the wipers themselves (their mechanical part) in the correct starting position.

Electrical breakdowns are as follows:

The electric motor does not work completely . After turning on the wipers, you can’t hear them working and the wipers themselves remain motionless. The cause of this breakdown will most likely be stuck motor brushes - then they need to be returned to the correct position. Less often, the armature burns out - in this case, you will have to completely replace both the electric motor and the gearbox (they are sold only as a set).

You can't hear the electric motor running . The wipers also don't move. After they are turned on, only the click of the bimetallic fuse is heard. The reason for this in winter is almost always freezing of the electric motor brushes. Often after this, when persistently trying to turn on the wipers, the bimetallic fuse or, less often, the electric motor armature itself blows. This problem can be easily solved by simply thawing the brushes and removing moisture from them. In more serious cases, you need to replace it with a new fuse or the electric motor itself.

The wipers work, but in intermittent mode they continue to run continuously . At the same time, there are no sounds of alternating rotation of the electric motor armature. This problem is usually solved by simply replacing the control relay. But before doing this, you just need to check and re-clean the contacts of the limit switch - they sometimes oxidize or burn.

The work of the wipers is carried out slowly and with stops in unpredictable places of the working stroke. The windshield wipers do not occupy the lower position at all. In this case, the cause is most often the limit switch - you need to adjust it by bending the contacts. If incorrect operation continues, the electric motor will have to be completely replaced.

All work on servicing VAZ 2110 windshield wipers begins with disconnecting the negative terminal of the battery. After this, the frill is disconnected. It is advisable to do this, since all subsequent operations are significantly speeded up.

Next, unscrew the mounting bolts and remove the entire structure of the wipers by moving them towards you. Their installation is carried out in reverse order.

Replacing wipers

When repairing an electrical component, you must first remove the dashboard to gain access and possibly replace the relay or fuse. After this, you can disassemble the steering column - the switch is located here. It also often needs to be replaced (for example, due to damaged insulation).

Often it is necessary to completely replace the wipers. Here you need to remember the following - wipers for all years of production of the VAZ 2110 are identical and interchangeable. If any other wipers are used (for example, foreign-made), then you need to make sure that their sizes match. The length of the VAZ 2110 wipers is exactly 20 inches (50.8 cm). Their increase by 1 - 2 centimeters will not be critical. But if the size of the wipers is much larger, then squeaking during operation, jerking and early failure are inevitable. The reason for this is that the permissible mass-dimensional load is exceeded.

Engines do not work for VAZ 2108, 2109, 21099 cars

Wipers failure. "janitors". A very common malfunction of VAZ 2108, 2109, 21099 cars. Its main causes are problems with the electrical part and mechanical damage to the wiper elements. Let's consider a situation where the wipers are completely out of order and in no way react to the movement of the lever in the right steering column switch.

List of malfunctions leading to failure of wipers on VAZ 2108, 2109, 21099

At the beginning of the electrician:

- blown fuses in the mounting block;

For old model mounting block. 17.3722 is No. 5 and No. 4, for new ones 2114-3722010-60, 2114-3722010-10, 2114-3722010-18. F16 and F7. Fuses No. 5, F16. Cleaner, No. 4b A7. Washer.

When the fuses blow, not only the windshield wiper circuits may be shorted out, but also other circuits protected by them may be shorted out. See “Fuses and circuits of mounting blocks of VAZ 2108, 2109, 21099 vehicles protected by them.”

— the windshield wiper relay is faulty (52.3747, 525.3747);

The relay must be pressed during operation. If this is not the case, either it is faulty or its contacts are oxidized. Sometimes removing it and putting it back in a few times is enough to restore its effectiveness. The faulty relay was replaced with a new one.

You can check if it works by moving the steering column switch to the highest position. In this position the brushes should work even if the relay is faulty.

Purpose of windshield wiper relay contacts for testing it: input. 15, exit. S.

— The operating modes of the steering column and the wiper switches are faulty;

The purpose of the switch terminals for testing it is: current input. 53a, 1st speed. 53, 2nd. 53b, intermittent mode input. 53e, intermittent output 53.

The faulty switch must be removed, disassembled, the contacts blocked or replaced with a new one.

— the connectors in the windshield wiper circuit were jumping;

In the mounting block these are X1, X2, X3, X4, X11, next to the mounting block there is an engine connection block and a cover for the steering column switch.

— oxidized contacts in the wiper circuit connectors;

In turn, disconnect all connecting pads and clean the contacts with a small file. It is better to start with a walk-behind tractor near the mounting block, as it is constantly moistened. Here you can check the connection of the engine ground wire.

— windshield wipers are poorly worn or sagging;

The commutator to which the brushes are pressed may also burn.

You can test the functionality of your windshield wiper motor by applying voltage directly to it from the battery. Input: 1st speed. Gray wire from the mounting block, 2nd speed. Gray-orange wire from the mounting block. Intermittent work input. Gray wire from the mounting block.

— the brushes froze to the glass;

— after a long period of parking, the brush is glued to the windshield;

— damaged, jammed or incorrectly installed windshield wiper drive levers after repair;

— the plastic gear teeth in the gearbox are damaged.
