A clean windshield is very important for the safety of the driver and passengers. Therefore, if the wipers on a VAZ 2107 do not work, this can lead to an unpleasant situation on the road. The article provides an electrical diagram of the windshield wiper, discusses malfunctions and solutions.

Windshield washer does not work

To remove dirt from the windshield, the washer is used together with the windshield wiper. The device sprays water or a special liquid. The main elements of this mechanism are:

• fluid reservoir;
• motor;
• nozzles;
• connecting tubes.

During the operation of a car with a washer, various problems may arise that lead to its inability to work:

• motor failure;
• fuse blown;
• kinking of tubes;
• breakdown of the steering column switch;
• poor contact on the power supply circuit.

Checking the motor

It is easy to check if the washer pump is not working properly. To do this, just open the hood and pull the lever of the steering column switch, which is responsible for the function of supplying fluid to the windshield. At this moment, the operation of the motor will be clearly audible. If this does not happen, then the malfunction may be caused either in the pump itself or in the fuse or other part of the electrical circuit. To make sure that the problem lies in the motor, we use a multimeter to measure the voltage when the washer is turned on. If there is voltage, but the pump does not work, then you need to take care of replacing it.

Video: checking the wiper motor on a “classic”

The VAZ classic windshield wiper does not work. We are looking for the reason. 1 part.

Injectors

If the motor is running, but liquid is not supplied through the nozzles, then the problem will not be difficult to identify, since there are only a few reasons for this phenomenon:

• clogged injector fittings;
• the supply tube has come off;
• kinking of the tube.

The malfunction can be determined by inspecting the tubes from the motor to the injectors. If there are no areas with kinks and the tube has not fallen off, then the reason lies in clogged nozzles, which can be cleaned with a sewing needle and blown out with a compressor.

Fuse and mounting block

The integrity of the fuse is checked in the same way as for windshield wipers. The same protective element as for the wipers is responsible for the operation of the washer. In addition to the fuse, sometimes the track in the mounting block through which power is supplied to the washer burns out. In this case, you need to disassemble the fuse box and restore the current-carrying element by soldering, having first cleared the varnish from the track.

Understeering's shifter

You should start checking the steering column switch on a VAZ 2107 if the fuse, motor and the entire electrical circuit through which voltage is supplied to the pump are in good condition. In this case, the wiring should not have breaks, melted insulation or other visible damage. To check the steering column switch, only a multimeter will be enough. Having disconnected the connectors from the device in question, we connect the probes of the device in the dialing mode with a two-pin block. If the switch is working properly, then when the washer is turned on, the device will show zero resistance. Otherwise, the mechanism will have to be replaced.

Repair of electric wiper motor

As mentioned above, difficult operation of the purifier may be caused by a malfunction of the engine. This is usually due to the fact that the lubricant in the bushings accumulates friction products over time and becomes very thick. The engine rotor begins to spin with difficulty, which leads to burnout of the winding or burnout of the commutator lamellas.

Secondly, when the wipers do not work completely when there is voltage, this is wear on the electric motor brushes. In some cases, with a slight blow to the engine, it began to work.

Below watch a video on replacing the wiper motor:

In cases where the windshield washer does not work, the motor is usually faulty. To check it, measure the voltage on the “+” yellow-black wire, if not, check fuse F2. If there is voltage, then use a piece of wire to connect the “-” black and white wire to the car body. The engine must spin, otherwise it is faulty.

There is nothing difficult in eliminating the described breakdowns. The necessary operations can be performed by any car enthusiast who knows a little about the design.

Dimensions

Thanks to the small size of the brush, you can save money. The length is identical for all positions. It is 340 mm. It is possible to install longer brushes. At the same time, they will not touch the body. The degree of cleaning of the windshield directly depends on the quality of the brush itself. You need to familiarize yourself with the characteristics in advance.

Original articles

Initially, only original parts were produced for the car. The year of release of the first car from the assembly line is the distant 1982. No imported parts were used. But it is not possible to find original components for installation on a VAZ 2107. After the collapse of the USSR, the release of this series continued.

But AvtoVAZ no longer produced such small parts as windshield wipers on its own. Finished products were purchased abroad, from third-party companies. As a result, assembly is significantly simplified

At the same time, it is important to understand that the quality of original wipers does not differ from products from third-party manufacturers

  Repair of wipers on VAZ 2107

All wipers on sale can be divided into categories:

• frame;
• frameless;
• hybrid;
• winter.

All modifications without exception have their advantages and disadvantages. You need to choose a certain category based on the operating conditions of the vehicle and the region where it is located. Driving style and speed are definitely taken into account.

VAZ 2107 wiper malfunctions

Replacing a burnt out motor

During the winter season, at sub-zero temperatures, wipers often stick to the windshield. The wiper motor is under a lot of load, and it burns out if the bimetallic fuse does not work or the fuse burns out.

Location of the glass cleaner and washer fuse in the mounting block

In such cases, it is necessary to replace the motor. To do this, you need to remove all the parts in a certain order:

• Unscrew the fastening nuts;
• bend the lever and remove it from its seat;
• Using a 22mm wrench, unscrew the trapezoid fastenings on both sides;
• remove the plastic inserts;
• remove the hood seal;
• remove power from the windshield wiper motor;
• remove it with the drive from the hole in the body;
• bend the protective cover, unscrew the fastening nuts;
• press on the protrusions of the slots on the reverse side, on which the wiper arms sit, so that they fall inward, move in different directions, the trapezoid with the motor will come out.

Video instructions for replacing the windshield wiper trapezoid

After disconnecting the mechanism parts, you can repair the gear or install a new motor. But the electric motor must be inspected, even if it is in working condition. It is a conventional DC electric motor, the rotation of which, through a worm gearbox, is supplied to a trapezoid.

You should disassemble and repair the electric motor only if you are confident in your plumbing skills!

• Size of wipers for VAZ 2107 size and length of blades

Walk over the collector with a cloth soaked in solvent. If there is a lot of wear, you need to change the armature or motor. Defects on the gear will require it to be replaced. Assembly occurs in reverse order. Therefore, before installing a replacement electric motor, you need to clean the trapezoid from contamination, lubricate the rubbing elements, motor and gearbox.

Trapezius problems

The trapezoid transmits rotational movements from the electric motor to the wipers and ensures the reciprocating movement of the wipers while cleaning the glass. Interruptions in the operation of wipers occur due to problems with the trapezoid; oxidized bushings and corrosion on the axles lead to jamming and slow operation of the mechanism. You can remove the trapezoid with a flat-head screwdriver. To set the correct position when installing the trapezoid, you must:

• set the motor to the initial position;
• place the crank and short rod parallel to each other;
• After that, attach the motor to the trapezoid.

Wiper relay not working

If the wipers fail to operate in intermittent mode, it can be argued that the relay has failed. First you need to check the power supply to the relay block. To do this, you need to remove the relay, turn on the wipers in intermittent mode, and check the voltage at the terminals. If no current flows, you need to repair the open circuit or replace the switch. The design of the relay is such that it cannot be repaired. So, if it does not work under voltage, you need to replace the part with a new one.

Wiper switch

To check the voltage supply to the switch, you need to remove the pads from the steering control or on the relay connection blocks. There is always voltage on the black-yellow wire. Check on the red and gray wires. If there is no voltage on one of them, then you need to change the switch.

Causes of fuse blown.

If the wipers do not work in two positions of the switch, then most likely the fuse has blown, which serves to protect the circuit from short circuits and overloads. When the wiper control lever is set to the "off" position and the blades do not stop at the bottom of the glass or anywhere else, the problem is in the gearbox. It is there that a special switch is installed, which ensures that after turning off the brushes remain in the desired position.

Due to heavy overload of the electric motor, overheating of the wiring, or exposure to water, the fuse may blow. Replacing it is easy, but the cause of the burnout must be found out and eliminated.

Windshield wiper motor, malfunctions and replacement

Welcome, friends, to the DIY car repair website. Windshield wipers are an indispensable attribute of any car.

Whatever the car is - cheap or expensive, domestic or foreign, passenger or truck, it must have wipers.

The main thing is that they are in good working order and ready to work. In this case, the main element that is responsible for the motor function is the windshield wiper motor.

Motor malfunctions and solutions

Let's look at what to do if the motor

windshield wiper, and what can cause such problems. There are several options:

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

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

In this case, you need to repair the windshield wiper motor - inspect it, replace faulty elements, and clean dirty components. It is important to check the integrity of the wiring that connects the electric motor and the block.

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

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

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

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

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

All wipers on sale can be divided into categories:

• frame;

All modifications without exception have their advantages and disadvantages. You need to choose a certain category based on the operating conditions of the vehicle and the region where it is located. Driving style and speed are definitely taken into account.

Frame

The classic type of construction has a metal frame. As a rule, frame wipers are the cheapest. They have advantages: durability, accessibility. Usually the price for a pair starts from 500 rubles. The disadvantage is the aerodynamic shape. As a result of air resistance, the contact strength of the windshield and wiper is reduced. Which leads to poor cleaning.

Frameless

Have less resistance to air flow. Therefore, they can cope with cleaning the windshield at any speed. They have a more presentable appearance than frame ones. Less durable.

Hybrid

They are free from the disadvantages of frame and frameless brushes. They are a single piece of rubber. But there is a metal structure inside. Which makes the brush more durable.

Winter

Winter wipers are distinguished by their elasticity - even at sub-zero temperatures they clean the glass well. The characteristics are achieved by adding rubber to the rubber from which the wiper is made. It retains its elasticity and is not subject to deformation. Easily tolerates strong temperature changes

This is especially important for regions with low average annual temperatures. Optimal choice:

• the temperature at which the car is operated;
• maximum speed - at which the movement is carried out;
• intensity of precipitation.

Electric motor of the tenth family - installation on a classic and replacement

The drive from the VAZ 2110 is ideal for classic VAZs and has the best characteristics. How to remove the motor was described above. Installing a new one is not difficult. The electrical part will have to be changed a little. There are more modes on the “ten” and in order to leave only two, we interfere with the motor.

VAZ 2107 Problems with wipers, solution, advice.

We tear off the petal soldered to the body (there may be a wire instead) and insulate it. We take out the wiring from the detachable terminal, there are only 5 wires. We bite off one of the yellow ones, it will not be needed. We strip the gray wire that goes to the capacitor, screw the yellow one to it, cut it off from the male wire, and isolate the connection. We remove the old block, insert 4 wires, starting from the top clockwise (the protrusion on the block is on the right). 1 – gray, 2 – blue, 3 – white, 4 – black.

The rear window of station wagon and hatchback bodies gets very dirty, which is why the VAZ 2111 and 2112 have a rear wiper installed. If everything is in order with the electrical equipment, we replace the electric drive. We remove the trunk lid trim: unscrew the screws and unclip the pistons. We unscrew the nut that secures the leash and remove it. We push two pistons from the inside and pull them out using pliers. We pry up the cover with a screwdriver, remove it and the protective cap. We unscrew one nut with a 24 wrench, two more with a 10 wrench. Disconnect the connector and remove the gearmotor.

How to replace the wiper relay?

To replace this relay, you need to move or completely remove the dashboard. To do this, you need to remove the plastic covers from the interior heater control levers.

Then you need to remove the plastic plug located on the right side of these levers.

Now you need to firmly grasp the right side of the tidy with your hands and gently pull it towards you.

To get a little more space, you can wedge the tidy by inserting an object into the space between it and the panel. If you don’t have the skill to replace the relay with the instrument panel removed, you will have to remove it completely. To do this, you need to unscrew the speedometer cable, remove the econometer tube from the fitting, and also disconnect the chips with wires.

Attention! Before dismantling the blocks with wires, you need to remember how they were connected, and even better, take a photo so as not to confuse them when connecting.

Now unscrew the nuts securing the wiper relay to the car body, disconnect the chip and pull it out. This relay can be mounted with one bolt or two.

Now we connect the chip to the new relay and assemble the panel in the reverse order.

How to change wipers on a VAZ 2107

Replacing wipers yourself usually does not cause any problems. In order to solve the problem, you need to carefully study the fasteners that are used to fix the frames. Usually this is a metal hook, which is why you need to choose cleaners with a suitable mechanism; for some, special adapter kits are sold that will help if the selected device has a different mount. Replacement usually takes a few minutes: just disconnect the old wipers and put new ones in their place. The mount has a latch that simply snaps onto the pin. It’s worth checking how the connection went; if it holds tightly, you can use cleaners.

Wipers on VAZ

Essentially, I wrote that operating a car with a faulty windshield cleaning system is prohibited, but driving when the wiper blades do not remove water and pollution is no better. My question is, is it possible to install a better carburetor one of these days with the GAZ 24. According to the text of the article, I would like to give their types, not in my opinion, what is the best wiper blade to install on the VAZ 2107.

Wiper size for VAZ 2107 13 inches

Replacement

The process of replacing the wiper on this car does not cause problems. It is carried out in two stages:

• install the wiper arm in a vertical position - perpendicular to the windshield;
• Carefully, squeezing the plastic fastener on both sides, wiggle the wiper away from the hook.

If you no longer plan to use a used wiper in the future, you don’t have to stand on ceremony with it. And pull it out with a jerk. If the driver plans further use: all operations must be performed carefully. Plastic becomes brittle from prolonged use in the sun. Temperature changes make it fragile. If possible, replacement should be carried out at above-zero temperatures: the likelihood of breaking fragile plastic will be reduced to a minimum.

High-quality wipers that perform their function well are the key to good visibility. Therefore – safety on the road. It is important to promptly change windshield cleaning blades. This will help you avoid accidents and other problems on the road.

Wipers VAZ 2107

The vehicle is operated in different climatic and road conditions. For safe and comfortable movement, the driver must have good visibility of the road situation, i.e. the windshield must always be clean. Windshield wipers provide mechanical cleaning of the windshield from dirt and sediment, improving visibility and increasing safety. We will consider possible problems with this mechanism and ways to eliminate them in more detail.

Principle of operation

The work of the wipers is quite simple and consists of the following sequence of actions:

1. The driver selects the desired operating mode of the windshield wipers using the steering column switch.
2. The entire windshield cleaning mechanism is driven by a motor.
3. The wipers move across the glass left and right at the selected speed, cleaning the surface.
4. When the mechanism is no longer needed, the steering column switch returns to its original position.

Wiring diagram for the wipers and windshield washer of the VAZ 2107: 1 - thermo-bimetallic fuse; 2 — windshield wiper gearmotor; 3 — electric motor for windshield washer; 4 — mounting block; 5 — washer switch in the three-lever switch; 6 — wiper switch in a three-lever switch; 7 — windshield wiper relay; 8 — ignition switch;

Components

The windshield wiper consists of the following main elements:

• lever mechanism (trapezoid);
• electric motor;
• relay;
• brushes

Trapezoid

One of the important elements in the windshield wiper mechanism is the trapezoid. On almost all cars this part is the same, and the difference lies only in the methods of fastening, the size and shape of the elements. The functioning of the trapezoid consists of transmitting rotational motion from the electric motor to the wipers, as well as ensuring the synchronous movement of the latter for high-quality glass cleaning. The trapezoid consists of rods, a body and a hinge.

Trapezoid design: 1 - crank; 2 - short thrust; 3 — joint of rods; 4 — rollers of the windshield wiper mechanism; 5 - long pull

Motor

The electric motor of the windshield wipers of the VAZ “Seven” is made as a single unit with a gearbox and is one of the main links of the mechanism in question. The motor consists of a stator with permanent magnets and an armature with an elongated shaft, at the end of which a screw is threaded. The purpose of this unit is to ensure the movement of the blades along the windshield. The device is considered reliable and fails very rarely.

Wiper relay

On classic Zhiguli cars, the windshield wiper has two operating modes - fast and intermittent with an interval of 4-6 seconds. It is to ensure intermittent operation that the RS 514 breaker relay is designed. Delayed activation of the wipers is used during light rain, when too frequent operation of the windshield wipers is not required, and when the mechanism is completely turned off, the glass is gradually covered with small drops of precipitation and needs to be cleaned. The product is connected to the general wiring using a four-pin connector. On the VAZ 2107, the breaker relay is located on the driver’s side on the left side panel under the plastic trim.

The wiper relay ensures intermittent operation of the mechanism

Brushes

Almost all passenger cars use two windshield wiper blades. On the “seven”, elements with a length of 33 cm are installed from the factory. Longer brushes can be installed, but a greater load will be placed on the electric motor, which will lead not only to slower operation of the mechanism, but also to possible failure of the motor.

The VAZ 2107 is equipped with brushes 33 cm long from the factory.

What is a windshield wiper motor?

All cars, trucks and other vehicles are already equipped from the factory with mechanisms for cleaning glass, including windshield wiper blades. In its standard form, it consists of two holders with rubber bands on the windshield and one holder on the rear window (for cars with a station wagon or hatchback body). All windshield wipers have three modes of operation, during which they move quickly, slowly or at an intermittent pace.

All windshield wipers are equipped with a special electric motor with geared torque transmission. Two mechanisms designed to operate the windshield wipers are attached to the motor shaft. One rotates the wipers to a certain position on the windshield, and the second is responsible for moving the wipers to their original position. The lever system supports the wipers throughout operation.

In fact, the electric motor rotates without stopping, and a special mechanism is responsible for moving the wipers, which allows them to rotate and quickly return to their original position. This mechanism is called a trapezoid wiper. It consists of a set of levers that move the wipers across the windshield.

In addition to the windshield wipers, the glass washer system is also responsible for a normal view of the front of the road. It is a tank with a special liquid, which, under the action of a pump installed in the tank, is pumped into the system and sprayed on the windshield. It is extremely important that these mechanisms are always in good working order. This is due to the fact that on the planned day of the trip the weather can easily turn bad and driving with a faulty windshield wiper system can become very dangerous.

Which wipers are better

Not only its price, but also its performance depends on what exactly the base of the purifier is made of. The quality of the base plays a major role in cleaning glass from moisture.

When choosing a product, you should pay attention to what it is made of. It could be:

1. rubber coated with graphite;
2. silicone;
3. Teflon spraying.

At first, graphite-coated rubber was used in wipers. They do the job well, but don't last long.

Silicone does not withstand low temperatures well, but otherwise always gives good results. 2 times more expensive than rubber ones.

Teflon has proven itself well in operation, but is expensive compared to conventional ones.

The manufacturer of the windshield wipers plays a big role. The highest positions in the ranking are occupied by: Bosch, Valeo, Heyner, Trico.

Where is the wiper relay located on the VAZ 2107?

VAZ 2107 is one of the most common cars in Ukraine. It is famous for its ease of repair and reliability. All this car needs is the care of the owner, good oil in the engine and gearbox and it will serve faithfully. One of its few problems is the wiper relay that often fails. This leads to the fact that the windshield wipers do not work at all, or their cycling gradually slows down. To restore the functionality of the device, the relay must be replaced, but this is not so easy. This article describes the location of the wiper relay on a VAZ 2107 and the process of replacing it with a new one.

How do wipers work and why are they needed?

The main task of windshield wipers is to create a good level of visibility in bad weather and to clear water and dirt from the car's windshield. Special auto chemicals and the use of the right washer can help them with this. Windshield wipers operate thanks to a special gear motor, powered by the vehicle's on-board circuit. And the relay marked RS-514 is responsible for the frequency of operation. The VAZ 2107 has two wiper operating modes - constant and cyclic, with a pause of four seconds. The efficiency of wipers is directly related to the quality of the battery; you can buy a good battery from us.

The windshield wiper relay, as one of the most important elements of the system, is located under the dashboard, on the left. It is fastened with two screws hidden under the upholstery. The connection is made using a special plug located near the headlight hydraulic adjustment handle. To check the device, the plug must be disconnected and pulled out.

Basic device

Knowing where the windshield wiper relay is located on the VAZ 2107 in the injection and carburetor versions is not enough. To carry out repairs, you should study the principle of operation. This device looks like a black box, inside of which there is a microcircuit and electronic components responsible for the proper operation of the wipers. The microcircuit consists of the following elements:

• electromagnetic coil;
• resistor and capacitor;
• microcontroller HP37.

Relay for wipers with adjustable pause VAZ
The connection is made using four wires, through which the windshield wiper motor is controlled.

How to replace the wiper relay

To begin with, it should be noted that in the carburetor and injection versions of the car the relay is absolutely identical. Next, you need to check the functionality of this device. The easiest way is to take a known working device from another machine and connect it. If the windshield wipers work, then the problem is here. In theory, if you have certain knowledge, you can try to restore it by identifying the failed element and replacing it. But if you need to fix your car urgently, the easiest way is to replace the device with a new one. This is very easy to do:

• Remove the negative terminal from the battery, de-energizing the entire on-board network of the vehicle.
• Unscrew 2 screws.
• Take out the plug, put it on the new device and screw it into place.

How does the wiper relay work?

The operation of the windshield wiper involves a chain of elements, which includes an electric motor, a fuse, a power button and a relay. The latter performs the most important function, managing the entire process. It functions as follows:

• When you press the power button, power is supplied to the relay, the contacts inside close, the coil turns on and the wiper gear motor starts working.
• Over the next 3 seconds, the bimetallic plate inside the device heats up, and the power from the electric motor of the VAZ 2107 windshield wipers is lost.
• After this, the panel cools down quickly enough and the wipers start working again.
• If the delayed operation mode is turned on, the main resistor distributes the electromotive force so that the delay necessary for the cyclic operation of the wiper is formed.

As you can see, the scheme is quite simple, and almost all repairs come down to replacing failed components with new ones, so you can do everything yourself.

VAZ 2105 and 2107 with injection engines

More modern and environmentally friendly 21067 engines with distributed fuel injection have complicated the electrical equipment of cars, which has led to the use of additional fuses. On new cars it was also possible to use a central lock.

A little earlier, two additional fuses appeared in cable-type holders, embedded in the circuits of the headlight glass cleaning motors. This was due to cases of mysterious battery discharge due to jammed gearmotors on the headlights. The new fuses were located near the rear right and left headlight housings. Everyone is responsible for their own side.
