VAZ 2114: wipers do not work - TOP 6 reasons and solutions to the problem

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.

We repair the device

In the VAZ-2107, the switches are located under the steering wheel of the car. If you suspect a malfunction, the first thing you need to do is find out the reason why this or that function does not work.

Repairing the switch

We remove the steering column switch on the seven. Having removed the first ring, then the headlight, stop and wiper levers, we get to the mechanism by which the turns are automatically turned off. We take it out and here lies the cause of all the troubles: between the reeds there is a spring that breaks off and does not move the reeds in different directions. It is necessary to replace the spring; you can use a regular spring from a ballpoint pen. Next, we begin collecting all the rings and levers in reverse order. After finishing the work, we check how the levers and the turning mechanism work. To do this, we connect the pads and place the terminals on the battery; if all functions work, then we have completed the repair.

Also, the cause of a malfunction of the turn switch may be contamination or oxidation of the contacts. You can clean dirty or oxidized contacts; to do this, you need to slightly bend the “sagging” springs and other accessible parts. As a rule, after carrying out such cleaning manipulations, it is possible to restore the functionality of the switch.

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.

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.

There is no intermittent wiper mode - looking for a relay

Often, along with the lack of intermittent mode, problems arise with returning the windshield wiper blade to its original position. In this case, the culprit of the situation is a burnt-out relay. At the same time, the mode of continuous strokes of the windshield wiper blade is present, as well as the mode of accelerated cleaning of the glass. These options for operating the windshield wiper are designed to bypass the relay; they are implemented directly from the handle for switching on the wiper operating modes. When a relay fails, you simply need to replace it by following this procedure:

• searching for the installation location of the relay in your car - again, forums, the car’s operating instructions or recommendations from specialists who repair your car will help;
• Next, the non-working relay should be removed from the installation location, the device number should be rewritten so as not to make a mistake when choosing a new electrical device to replace it;
• go to the store or order on the Internet an original production relay with the same catalog number to ensure normal operation of the wiper on the car;
• Having received the device in your hands, take a good look at it, make sure that this is exactly the element that was originally installed in your car at the factory;
• turn off the ignition, be sure to check that the wiper switch is in the “off” position and insert the relay into the slot from which the non-working device was removed;
• turn on the ignition and check the quality of the wipers, taking into account the new installed electrical part.

The operating modes of wipers on budget cars are often quite poor, so you can develop them by installing a relay from the same manufacturer, but with different parameters. For example, it is popular to install not a simple wiper relay on domestic cars in the basic configuration, but a special relay with adjustable brush response pause. This is a good option that can significantly improve the emotions of driving a car and make the driver’s job easier.

Fuses and other electrical connections

Not the last option for a problem in the wiper operation system is electrical connections and circuits. The first step is to check the fuses, which tend to fail and simply do not allow electric current to flow to the right place. Most cars have fuses under the hood; some models should be examined for a fuse box in the passenger compartment.

Broken wires can also be one of the possible problems. If, for example, after a garage service your wipers do not work, it is quite possible that the technicians cut the wires and did not fix the problem. You should trace the wiper circuit, if possible, but it is better to take the car to a normal station and order a proper repair of this problem.

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.

Control unit malfunction

A sign of a malfunction of the control unit is the lack of response of the windshield wiper mechanism when the fuse, electric motor and all wiring are known to be good.

Often it fails not due to mechanical failure, but due to oxidation of the contacts. To identify possible causes, the unit will have to be disassembled, inspected and, if necessary, the contact elements cleaned.

If this does not help, the unit should be replaced.

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.

Let's sum it up

If reliable operation of the windshield wiper is your priority, you should pay attention to all possible ways that parts may fail. The knocking trapeze should attract your attention and in a certain way force you to examine the situation. Most likely, the knocking will lead to the fact that you will soon have to replace the device with a new one and buy high-quality replacement parts. But it is quite possible that you just need to get to the trapezoid and tighten the fastenings of its parts in order to eliminate the knocking and continue to operate the device perfectly.

High-quality work of wipers is necessary in any car, so you should immediately solve all problems that arise, taking into account their features and technical difficulties. Replacing the relay can be done in a garage, but it is better to change the trapezoid and wiper motor in a service center. This way, you can get the necessary capabilities for operating the machine without any problems and acquire the necessary performance qualities of peripheral devices. Have you ever encountered problems with your wipers?

Don't know why the wipers turn on when you turn on the ignition, and you can't stop it? You can, of course, turn off the fuse and drive without wipers for a while, but the problem must be solved completely.

The classic way to solve the problem usually comes down to two options: disassemble the steering column switch and clean the inside, or install a toggle switch responsible for separately turning on the wipers. But in fact, there are much more effective solutions to this problem.

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.

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.

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.

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.
