What to do if the wipers on a VAZ-2110 do not work: possible reasons

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.

Replacement procedure

So, you have chosen a gear motor for your VAZ - one of the first three. Let's look at how it is replaced. When performing this work, there is no need to disassemble the entire windshield wiper system. We proceed like this:

1. Disconnect the negative terminal from the battery;
2. Having noted the position of the brushes on the windshield, unscrew and remove the levers;
3. Remove the cover from the fairing;
4. Unscrew the nut securing the crank mechanism bracket to the motor axis;
5. Unscrew and remove the bracket itself. It is secured to the body with 3 bolts;
6. We remove the non-working or poorly functioning motor from the studs;
7. Replacing the old one with a new one is done in the reverse way.

Refinement stages

Wiring
It is easy to modify or replace wipers. To do this you need to take several sequential steps:

• Disconnect the negative cable from the battery;
• Pull the wiper towards you;
• Remove the existing brushes;
• If there is a decorative trim, remove it;
• Unscrew the mounting bolt, thereby removing the old wiper;
• Compare the dimensions of the old and new cleaner;
• Ideally, the new device should not exceed the old one by more than 20 millimeters;
• Reverse the assembly procedure.

As you can see, changing windshield wipers is not difficult. But with the repair procedure, everything is somewhat different. But following the instructions, even an inexperienced VAZ 2110 owner will be able to do everything with his own hands.

You can’t go far without wipers in rain or snow, so today we will discuss the topic of why wipers do not work on a VAZ 2110, and what to do in such a situation.

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:

1. Mechanical;
2. Electrical.

Consider mechanical breakdowns

1. 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.

1. 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:

1. 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).

1. 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.

1. 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.

1. 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.

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.

1. Remove the dashboard.
2. 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.
3. Next, check the condition of the fuse that controls the operation of the windshield wiper drive.
4. 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.
5. 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.
6. 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.
7. 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.

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:

1. When the electric motor is running, the brushes do not move.
2. 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.

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.

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.

How to repair

Don't be upset if you find that your windshield wipers refuse to work and run to a service center. In the VAZ-2110, with enough knowledge, you can fix everything yourself.

1. Remove the dashboard.
2. Find the relay that is bolted to the body.
3. Now you need to check whether the fuse responsible for the wiper drive is working.
4. Then the steering column is disassembled, which makes it possible to see the condition of the switch. Replacement will be required if the insulation is damaged or there are any other flaws.
5. Now unscrew the motor from the body and check if it is in working condition. If the damage is minor, repair will help, otherwise replacement along with the relay is necessary.
6. You also need to inspect the drive, since it may be the cause of the malfunction, namely the breakdown of its pulley.

Stories from our readers

“Fucking basin. "

Hi all! My name is Mikhail, now I’ll tell you a story about how I managed to exchange my two-wheeler for a 2010 Camry. It all started with the fact that I began to be wildly irritated by the breakdowns of the two-wheeler, it seemed like nothing serious was broken, but damn it, there were so many little things that really started to irritate me. This is where the idea arose that it was time to change the car to a foreign car. The choice fell on the melting Camry of the tenth years.

Yes, I had matured morally, but financially I just couldn’t handle it. I’ll say right away that I am against loans and taking a car, especially not a new one, on credit is unreasonable. My salary is 24k a month, so collecting 600-700 thousand is almost impossible for me. I started looking for different ways to make money on the Internet. You can’t imagine how many scams there are, what I haven’t tried: sports betting, network marketing, and even the volcano casino, where I successfully lost about 10 thousand ((The only direction in which it seemed to me that I could make money was currency trading on the stock exchange, they call it Forex. But when I started delving into it, I realized that it was very difficult for me. I continued to dig further and came across binary options. The essence is the same as in Forex, but it’s much easier to understand. I started reading forums, studying trading strategies. I tried it on a demo account, then opened a real account. To be honest, I didn’t manage to start earning money right away, until I understood all the mechanics of options, I lost about 3,000 rubles, but as it turned out, it was a precious experience. Now I earn 5-7 thousand rubles a day. I managed to get the car buy after half a year, but in my opinion this is a good result, and it’s not about the car, my life has changed, I naturally quit my job, I have more free time for myself and my family. You’ll laugh, but I work directly on the phone)) If If you want to change your life like me, then here’s what I advise you to do right now: 1. Register on the site 2. Practice on a Demo account (it’s free). 3. As soon as you get something on the Demo account, top up your REAL ACCOUNT and go to REAL MONEY! I also advise you to download the application to your phone, it’s much more convenient to work from your phone. Download here.

1. Check fuse F9 20A in the mounting block. 2. At the same time, we check the relay for switching on the windshield wipers and windshield washers (install a known good one for testing, check that the relay is not installed on the other side). A faulty relay occurs when the intermittent wiper mode does not work. 3. Poor electrical contact. There can be many options, for example, the wiring has melted, poor ground contact, poor contact in the block with the wires in the engine compartment due to exposure to moisture, faulty mounting block, etc. We check the presence of voltage on the electric motor pads. 4. The steering column switch is faulty. 5. The nuts on the trapezoid have become unscrewed or loosened. For example, a nut securing the crank to the gearbox axle. Check the windshield wiper trapezoid, tighten the nuts. 6. The windshield wiper trapezoid is jammed. Repair, lubricate or replace. 7. The electric motor is faulty or its fuse (separate) has blown. We check the voltage supply. If necessary, we repair or replace with a new one.

If the windshield washer does not work, check:

1. presence of water in the tank;
2. condition of the windshield washer pipes;
3. relay and fuse F9 20A;
4. washer motor.

Let us remind you that if you are not satisfied with the operation of the windshield wiper, then by modifying the washer system as a whole, or separately, for example, increase the cleaning area of ​​the wipers or modify the relay.

Have you encountered a malfunction in the operation of your car wipers?

If it's snowing or raining outside, wipers become indispensable elements of the car.

Wiper elements for VAZ 2110

In our material we will talk about the mechanism of the VAZ 2110 wipers, discuss the main reasons for their malfunction, the issue of repair and the search for alternative options to standard windshield wipers.

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.

Alternative solutions

Most car owners of the domestic “ten” are accustomed to replacing worn out and faulty windshield wipers with similar ones.

Often this happens because they do not see alternatives and are not familiar with them.

But this size can be increased to 530 millimeters. It is not recommended to install more, since this way the windshield wiper will not be able to work effectively, and the drive simply will not cope with the load. As a result, too long brushes cause squeaking and jerky work. Plus, don’t count on a long service life of the wiper mechanisms.

The original windshield wipers for the 10 are quite good. But there are more expensive, but also more highly efficient, high-quality devices.

Today it is fashionable to use frameless wipers, especially from Bosch. Their advantages lie in their compactness and a special, reliable leash mechanism.

But as practice shows, on the windshield of the VAZ 2110, as well as other VAZ models, they do not look very nice, because the fasteners on the leash turn out to be massive. Although if you modify them a little, you will get a very good result.

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.

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.

Check to see if the new brushes are squeaking and how they obey the “commands” of the switch. They should work quickly at high engine speeds, and slowly at low and intermittent modes. That, in fact, is the entire repair of VAZ wipers.

Replacing the trapezoid

The replacement process is simple, but it involves manipulations that require increased attention and accuracy - there is a danger of damage to neighboring components and mechanisms.

We de-energize the car by removing the “negative” terminal. We remove the special wind cover (the so-called “jabot”) and the expansion tank. The latter must be removed at an angle - there is a possibility that some of the coolant will spill out, so it is useful to first drain some of it into a previously prepared container.

Then you need to turn off the gearmotor

To do this, remove the corresponding connector. Carefully pull out the trapezoid (depending on the year of manufacture, it can be attached to two or four studs) and carefully remove it from the air supply box

That's it, the work is completed.

Installation of a new trapezoid is carried out in the reverse order.

How to remove the windshield wiper trapezoid

To remove the trapezoid you will need:

• key to 10;
• thin flat screwdriver;
• crosshead screwdriver.

First of all, you need to remove the wipers. To do this, you need to remove the plastic pads and unscrew the nuts with which they are attached to the trapezoid studs. Then unscrew the screws and side fastenings of the protective casing (jabot) and remove it. If the fasteners do not come out, treat with WD-40. Before removing the casing, make sure to remove all screws, bolts and nuts. If the cover does not come off, look for a fastener that you did not remove. Lifting the frill, disconnect the washer fluid supply tube from the tee, and then move the casing to the side.

Remove the belt that supports the radiator tank and move the tank to the side. Then pull out the partition (sound insulation), which is located behind the tank. Don't forget to remove the washer fluid supply tube from it. Disconnect the electric motor power connectors. After this, unscrew the bolts securing the trapezoid and electric motor. To remove the trapezoid, you must either struggle for a long time, coming up with various options, or place a thin flat-head screwdriver under the far end (relative to the motor) of the lower rod of the trapezoid and pull out the entire structure as if on a slide. You can also turn the left edge of the trapezoid clockwise and pull it out, then remove the engine.

Putting the trapeze in place

Usually, installing the trapezoid into place does not cause difficulties. Insert it and secure with bolts. Do not overtighten the motor mounting bolt; the motor may need to be turned slightly to get the trapezoid to operate smoothly. After making sure that the trapezoid is working properly, tighten the electric motor mounting bolt, install and secure the sound insulation, frill (do not forget to connect the washer tube), and the expansion tank. Insert the plastic plugs and install them in place, install the arms with brushes and check the operation of the wipers in all modes.

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.

Wipers do not work on VAZ 2110: causes and solution to the problem

If one fine morning the wipers on a VAZ 2110 fail to work, the causes of this malfunction should be established. To do this, you need to get to the windshield wiper device.

The VAZ 2110 has three operating modes:

• Intermittent;
• Constantly fast, in case of heavy rain;
• Constantly slow.

Owners of the VAZ Ten probably encounter noise and crackling noise when they turn on the wipers; this is often due to a malfunction of the electric motor.

Wipers are one of the most vulnerable systems in a car. The windshield wiper system has to work, for example, in severe frosts. In this case, you should check whether the blades freeze to the windshield, otherwise the electric motor may burn out.

If the electric motor of the engine does not show signs of life, the problem may lie not in it, but, for example, in the blown fuse F5 in the mounting block. It is located on the left side of the car, under the headlight control. If the fuse turns out to be fully operational, the problem lies in the power supply to the wiper motor. It is necessary to check the electrical circuit that connects the gear motor, fuse, steering column lever and the switch itself. A multimeter will help determine which part of this circuit there is a malfunction. If the monitor shows “zero”, the area is working properly. You see an infinitely large series of numbers on the screen - this is a reason to check all the terminals and wires.

The problem with poor current supply is solved as follows:

• Clean and crimp the terminals in each block;
• Completely change all wires;
• Change the wiper switch lever.

In the first two positions, the K2 relay type 524.3747 in the mounting block and the steering column switch itself are responsible for the intermittent operation of the wipers

If the wipers work properly in the third position, you should pay attention to the relay. If the relay is faulty, the wipers can work in intermittent modes without complaints, but there will be no characteristic pauses when switching

If the wipers switch without pauses, then the limit switch is failing you; it is located on the cover of the gear motor.

If burning or oxidation is present, you should:

• Clean up oxidation;
• Remove traces of burning if they are present on the contacts;
• Bend the contact tabs if necessary.

Folding the contacts will help if the wiper blades are slow, stop where they want to be, or don't reach the lowest position. If this solution does not help at all, you will have to change the entire gearmotor.

Device design

ten The three-speed windshield wiper system is one of the most vulnerable in the domestic “ten”. Almost any component can play the role of a weak point: steering column switch, relays, fuses, gear motor.

The design of the windshield washer on the VAZ 2101 consists of a gearmotor powered by an incoming current that drives the washers, a switch, a switch, a relay for switching on the intermittent mode, an additional relay, etc.

Glass cleaner device

The node consists of:

1. Windshield wiper trapezoids: with its help, the motor transmits movement. It wears out quickly, so sometimes repairs to the trapezoid are necessary.
2. An electric motor drives the wipers of the VAZ 2110. If the motor burns out, the entire unit will fail.
3. The windshield wiper pump pumps cleaning fluid. If the electric pump breaks down, then, despite the operation of the wipers, the windshield will not be cleaned.
4. The purpose of the tank is obvious - window cleaning liquid is poured into it.

Thanks to the electric motor, the wipers on the VAZ 2110 can operate in three modes:

1. Intermittent. The switch lever is in positions II and III.
2. Constant - with a low speed of movement of the brushes. The switch lever is in position IV.
3. Constant - with fast movement of the wipers. In this case, the shift lever is in position V.

Wiper circuit

First, let's try to understand how the windshield wiper circuit on the VAZ 2110 works and what components form a solid unit called a windshield wiper.
