Why the wipers work slowly on the VAZ 2114

Are you faced with the fact that your VAZ-2109 wipers are working slowly? It doesn’t matter, this problem haunts many motorists. A careless mechanism, which only yesterday worked like a clock, has a stupid habit of slowly and inexorably breaking down. This unpleasant feature of cars of this brand has already managed to annoy all owners of the VAZ model 2109, if you believe the reviews of the majority of domestic motorists.

There can be a huge number of reasons for this, and it is not always due to driver negligence. Windshield wipers often fail due to banal technical imperfections in the design of everyone's favorite VAZ. But you shouldn’t scold the manufacturers prematurely and go to a car service center. Speeding up a worn-out mechanism with your own hands is simple and anyone can do it.

Main reasons and methods of repair

Trapezium problems

The most common reason for poor windshield wiper performance is a rusted trapezoid.

As an emergency remedy, you can spray WD on the wiper mounting axles. If you are on the road and cannot service your car, this will help solve the problem for a while.

It is necessary to remove the trapezoid, clean it from dust and rust, and lubricate all moving parts with lithol.

Sometimes the problem can be fixed by simply changing the wiper brush holders.

Wear and contamination of the gear motor

To eliminate the malfunction, the motor is removed, sorted out, cleaned of dirt and then sanding the petals, lubricated and reassembled.

Incorrect installation

When replacing linkages or other wiper parts, some connections may have been connected incorrectly.

Electrical problems

If you bought a new trapeze, changed the motor, and the windshield wipers still do not work well, you need to inspect the section of the electrical circuit corresponding to them.

To determine why the wipers on a VAZ 2114 work slowly, use a voltmeter to measure the voltage drop across ground and along the positive wire. Then the losses at each contact are recorded separately. In some cases, losses on one connection can reach 0.8 V. Having identified the main causes, they eliminate the faults, starting with the largest sources of leaks.

Replacing the motor

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

There are different reasons:

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

All this suggests that the motor needs to be changed. In fact, this is the simplest three-speed electric motor. Its design includes a fuse. It can be located on the body or hidden inside the unit. Replacing the element is not difficult; you just need to remove the four bolts responsible for fastening it.

To avoid breaking the teeth of the new gear motor due to the crank (the curved rod that connects the motor and the trapezoid arms), proceed in the following sequence:

Turn off the safety block.
Mark the crank position.
Disconnect the crank fasteners.
Unscrew the trapezoid fixing bolts.
Remove the motor.

Quick diagnosis by weight

The ground outlet is located on the lower bolt of the windshield wiper drive, in the sump. If you suspect that the problem is a bad ground, turn the windshield wipers on maximum and note the speed of their movement. Then turn on the stove. The heater and wipers are connected to the same ground output, so if this is the problem, the speed of movement of the wipers after turning on the heater will decrease significantly.

To fix the problem, find the ground outlet, clean the contacts, solder the terminals if necessary, coat the connection with protective grease, and tighten the fastening nut well.

If you need to quickly eliminate voltage losses, extend an additional ground wire to the wiper motor mounting frame.

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.

Mechanical contamination and damage

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

Other reasons

Standard relay. With intensive use, the standard relay may not withstand the load and break down after six months. To improve performance, the standard relay is replaced with a relay with adjustable delay (adjustable pause).
Water in the mounting block. If water gets into the CN, it is removed and the nature of the damage is determined. Most often, if the contacts are damaged, the unit must be replaced.
Cold soldering of relays. Unfortunately, the quality of domestic spare parts sometimes leaves much to be desired. If, after removing and disassembling the relay, you find poor-quality cold soldering, re-solder all contacts.

Minor tuning: wiper relay with adjustable pause and optical rain sensor

The rain sensor has only come into full use in the last decade. The sensor makes driving in the rain much easier, freeing the driver from working with the right steering column switch. Today this is not only a salon option. There are a lot of online stores where you can pick up a “relay-optical rain sensor” combination for a specific car and install it yourself.

Setup of purchased kits is carried out according to the instructions. The usual system provides several modes, for example, rain, snow and a standard pause of a few seconds. On-demand operation is not disrupted - if you need a second speed, turn it on. Same with the third one.

An alternative to a rain sensor is a relay with an adjustable pause. It costs a penny, it only takes a few seconds to install, and the effect is very good. Electrical equipment allows you to change the pause depending on the conditions while on the road while driving. Another nice bonus is that you can choose a part with a different cycle of operation of the windshield wipers in washer mode.

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:

Damage to system levers. Even a slight change in the shape of these parts can affect the speed of the mechanism.
Faulty power cords. If there is not enough electricity supplied to the system, it is no wonder that it will slow down.
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.
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.
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.

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.

True problems and ways to solve them

The mechanism’s motor and the windshield wiper trapezoid itself are the main pitfalls of this malfunction. Once you forget about them for just a couple of months, the wipers begin to slow down, gradually becoming unusable. Unfortunately, there is no easy way to find out about this problem. You can learn how to properly and promptly care for a car only by facing all its shortcomings face to face or by asking your friends, at worst.

The thing is that without timely cleaning and lubrication, both parts quickly wear out and eventually refuse to work. Trapezium malfunctions lead in frequency of occurrence. Either the hinges begin to jam, or the strips bend for unknown reasons. However, the motor is also not far behind. Coupled with the loss of voltage due to damage to the wires, the part causes many problems, sometimes forcing an inattentive driver to buy a new one if he does not check the serviceability of the electrical wiring.

So what can you do to return your wipers to their former speed?

The answer is simple: disassemble the mechanism, clean and sand the motor with sandpaper, lubricate the hinges located between the trapezoid bars - that’s all.

Unfortunately, if this does not help, and you have not found any other faults, only replacing parts or a trip to the service center can help you. However, replacing the notorious trapezoid or motor solves the problem in most cases.

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. Adverse weather conditions at this time create poor visibility on the road, and, consequently, very difficult vehicle movement. It is precisely these problems that windshield wipers help to cope with.

The main causes of wiper malfunctions

Modern equipment should have such ideal properties as combating natural disasters, the ability to not succumb to frost, not dry out at high summer temperatures, not leave scratches on glass, as well as a long service life.

The most common causes of breakdowns

.
which can lead to the fact that the wipers on the VAZ 2109 will work slowly
. The following can be included:

deformation of the mechanism levers;
freezing of brushes to the windshield;
damage to the switch system;
damage to power cables;
foreign objects entering the mechanism;
damage to the wiper relay;
oxidation of wire ends;
origin of a short circuit in the winding;
severe contamination of any parts.

Dimensions

In fact, the size of the wipers on the VAZ 2114 plays a fairly large role in the quality and efficiency of glass cleaning.

Windshield wiper wiring diagram

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

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

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

The windshield of the VAZ 2114 has two blades of the same size - 51 centimeters. The brush on the driver's side can be replaced with an element 53 centimeters long, but on the passenger's side it is important to leave 51 cm. Otherwise, a strip of cleaned water will remain on the glass between the driver and passenger.
There is also a cleaner on the rear window of the VAZ 2114. But in this case, the size of the element is 30 centimeters. It is possible to install the wiper at 33 centimeters, which allows it to fit perfectly into the dimensions of the rear window. Some even install components at 40 centimeters, but in this case you will definitely have to increase the wiper stroke limit. To do this, remove the motor, shift the teeth by several units and put it in place.

What to do if the wipers on the VAZ 2109 are slow or faulty

If the car's windshield wipers no longer perform their functional tasks correctly, then certain repair work will be required. To do this, you need to arm yourself with a standard set of tools.

To begin work on identifying faulty parts of the mechanism, you need to completely disassemble

.
After this, it is recommended to follow this procedure
:

Check the condition of the electric motor structure, its windings and the armature shaft. You should carefully inspect all parts for any damage or deformation. If large scratches or damage are found on the surface that cannot be sanded, then it is better to replace such parts with new ones.
Determine the condition of the brushes and their springs. If damage or loss of elasticity of the mechanisms is detected, they must also be replaced.
Check how freely the brushes move in the special holders. The fact that they are difficult to move may cause the VAZ 2109 wipers to work slowly
. If there is any binding, you can try to correct it with sandpaper. If there are cracks, chips or high levels of wear, it is better to replace the brushes. You may need a soldering tool to replace them.
Inspect the condition of the collector. If there are traces of carbon deposits on the surface of the device that arise from friction with the brushes, you can try to eliminate this fact with a special polishing paste. There should be no damage to the commutator in the form of scratches or burrs. If such are present, then you need to treat these places with sandpaper. When these methods do not help get rid of defects, it is necessary to replace the part.
Inspect the design of the gearbox drive. Its gear should not have chipped teeth or any other defects. If there are any, it is better to install a new gear.
Check the wiper drive rods. They should not be bent under any circumstances. If there are minor deformations, you should try to correct them using certain available means.
Determine the condition of the threaded elements of the lever shafts in the wiper mechanism. If the threads are damaged, the rods must be completely replaced.

Diagnosis - disassemble

The key reason for windshield wiper failure is the wear of the trapezoid bushings that transmit rotation to the wiper arms. Wear, of course, is a flexible concept. Thus, banal dry operation significantly reduces the speed of the mechanism. There are even cases of asynchronous operation, when one leash rotates as expected, and the second moves with a delay.

In advanced cases, the bushings jam, and the wipers completely stop responding to the driver’s commands. Basic observations will help you determine that the problem is really in them. When the windshield wipers are turned on, a heavy hum will appear in the area of the motor, and the on-board equipment lamps will noticeably dim.

The diagnosis in such a case is absolutely obvious - disassembly followed by troubleshooting. Perhaps everything can be done by smearing it with a thick compound that does not attract dust. It is quite possible that something else will happen: you will have to look for a new trapezoid. But in this matter there will most likely be difficulties. Owners of older foreign cars will have to look for spare parts at disassembly sites, and car dealers will have to study the difference between counterfeit and original. Yes, there are a lot of new parts for the same Priora, but there are no guarantees that the “new” one will be better than the previously used mechanism.

Another obvious thing. The trapezoid, whether used or new, needs revision. Simply lubricating the moving parts is enough and long-term trouble-free operation of the mechanism is ensured.

Next in line is the gear motor. The output shaft of the mechanism may suffer the same fate as the trapezoid bushings. The shaft supports suffer from poor-quality lubrication, slowing down the operation of the mechanism on the way to the trapezoid. Analyzing the state of the mechanism is not difficult. After dismantling the trapezoid, connect the electric drive to the on-board electrical network and evaluate its operation in various positions of the steering column switch.

Swapping wiper speeds

Everyone knows that the VAZ 2110 windshield wiper blades have two speeds (slow and fast). The improvement is to swap them. To do this, rearrange the wires in contacts 53 and 53b in the steering column switch.

Standard operating modes of wipers:

Intermittent mode, slow.
Constant mode, slow.
Constant mode, fast.
Washer - constant mode, slow.

Operating modes of windshield wiper blades after modification:

Intermittent mode, fast.
Constant mode, fast.
Constant mode, slow.
Washer - constant mode, fast.

You can forget about slow wipers! The result of the first speed in the video:

Wipers do not work well due to lack of power

Another way to get rid of a slow windshield wiper is to replace the motor with a more powerful one. for example, from a foreign car (the standard motor of a VAZ 2110 is 7.5 watts, and from a Volkswagen Transporter is 40 watts).

The modifications presented in the article are also suitable for owners of VAZ 2109, 2114-15, etc. What methods of increasing the speed of brushes do you know? Let us remind you that the site also presents other improvements to the wipers that will solve problems associated with poor glass cleaning (for example, an increased size of the brushes or a cleaning area). Also work on improving the washer performance.

actually the subject. sometimes they even stop in the middle of the glass. the glass is clean. when working, they move slower than cars of similar brands. I cleaned the mass (which is in the compartment where the motor is), twisted it, and installed a new crown washer. did not help. Is there a problem with the motor? or maybe somewhere else. if in the motor, then change/repair? If you are repairing, does the disassembly process have any special features?

in short Yesterday after work I went to the garage. I removed this comb structure. (if anyone takes pictures, don’t believe the Murzilka where they say that you need to take the relays out of the CY - unscrew it completely). I took apart what I could, cleaned and lubricated. The trapezoid segments are two riveted strips, between which there are hinges. Obviously I couldn’t get to them - I somehow cleaned and anointed them. I also disassembled the motor, but didn’t find anything criminal; I sanded it and cleaned the lamellas for prevention.

collected. While collecting, I came up with many new vocabulary constructions. Fak. It didn’t help at all!.

Try to supply voltage to the motor directly from the battery, just look at how to do it correctly according to the diagram. If it “comes to life”, you will know where to look. _________________ The only incorrigible drawback of “Zubilka” is the lack of time to correct its other shortcomings

Nah. That's what I'm saying. maybe the engine is dying? _________________ And again all the same. with stupid questions and a stupid expression on his face. =)

Rover 400 1.4Si, VVC Inlet › Logbook › Wipers. A little theory and practice.

You buy new wipers, install them, but they don’t work. Well, that is. clean, but with gaps in the middle or the wiper bounces on the glass.

If these symptoms are yours, then your wiper blade is: 1. not perpendicular to the glass 2. not pressed hard enough 3. both together.

Here's the thing. When the wiper moves, its cleaning edge should bend against the direction of movement. Like a broom used to sweep the floor.

For this purpose, the elastic band has a special shape with a thin middle part, and there is a gap a little closer to the glass - this is to limit the bending.

Here's a picture. In principle, everything is clear:

If the wiper is initially installed at an angle to the glass, then when moving in one direction the rubber band rests too heavily on the glass and may not work (in this case there will be no gaps, but there will be poor cleaning, a layer of dirt or water may remain), and in the opposite direction - the rubber band It may not bend and then the wiper will bounce above the glass. At the same time, a grinding sound is heard or even jumps are visible. If the deviation is small, there may be uncleaned areas of glass on the move towards the side against the bend, when the rubber does not bend enough.

This can be done simply - the wiper is removed, the leash is lowered onto the glass - if you can see that it is pressed to the glass not in the middle, but at the top or bottom - take a screwdriver, insert it like a wrench into the end of the leash, and the leash is twisted. This is done until the lowered leg of the leash touches the glass with the middle. The procedure will have to be repeated a couple of times every other day.

In 99% of cases, problems with wiper slippage are solved and people, surprised by the ease of the solution, happily continue driving :):)

But it can be worse and this is my case. (

I've noticed for a long time that the wipers don't rub well. I still couldn’t find ones that would press evenly. Sometimes they don’t rub a little in the middle, sometimes they let it through almost entirely, sometimes only in one direction...

My leash is perpendicular to the glass, which means the problem is either in the shape of the glass or in the clamping force...

I changed the glass, but the effect remained.

When I installed the Bosh Aero Twin, it became easier, they clean better, but the passenger wiper began to leak in salty weather. And then the driver's license. Moreover, it is clear that a layer of dirt remains on the glass; it is smeared, but cannot be removed.

He turned on the wipers, got out of the car and pressed the leash with his hand. The wiper worked much more efficiently. Hm. I thought... swapped the wipers.

The passenger wiper began to clean the glass on the driver's side perfectly, and the driver's wiper began to clean the passenger side a little better.

Well, I see... it's a matter of pressure.

It was possible to tear the windshield wipers off the glass by hand without any effort at all. I compared it with several rovers even from the same 1998s-2000s - the pressure is twice as strong everywhere.

I tried buying fresh springs, but to no avail.

Today I freaked out and took off the wipers.

We were lucky with the design!

The spring is held on one side by the claw of the leash, and on the other side by a metal bracket (needed so that the wiper can be raised above the glass). The springs came off with great difficulty, I bent the brackets more strongly using a vice - I shortened them by 4 millimeters. And then for a long time and tediously I couldn’t put the springs back :):):) I needed an assistant to hold the chair, otherwise 1 couldn’t
