Contacts of steering column switches for VAZ 2108, 2109, 21099 cars

Rear wiper VAZ 2109

Windshield wipers, wipers, brushes are essentially the same thing.
As a rule, we remember their existence only when it starts to rain or when another bird flying by promises us great wealth right on our face :-). It is then that we remember the existence of these miracle devices that can so easily and effortlessly do all the dirty work or simply provide us with normal visibility in the rain, necessary for safe movement. According to the “law of meanness,” the wipers will stop working exactly at the moment when it rains, snows, or when the glass needs cleaning. But this doesn’t make it any easier; the fault needs to be eliminated, but before that it wouldn’t hurt to find it. In practice, it turned out that finding the reason why the engine does not start is much easier than understanding why the rear wiper of a VAZ 2109 does not work . Honestly, at first, I didn’t even know where to start and what to actually check, the mechanism is as simple as “two rubles” and there can’t be any failures, but the fact remains that the wiper doesn’t work and doesn’t react to anything.

As you may have guessed, today we will talk about the rear wiper, or more precisely about why the rear wiper of the VAZ 2109 .

So, let's figure out what, how and why.

Windshield wipers do not work: the motor turns and the blades are in place:

• The reason for this may be poor contact or severe wear of the gearbox drive shaft.
• The nut securing the trapezoid to the drive has come loose.

The rear wiper does not work and there is no sound from the motor:

• Perhaps the steering column wiper switch has failed. Check the voltage on the wires with a tester.
• The windshield wiper drive (motor) itself has failed.

The problem is with the contacts that go to the motor or in the gearbox itself. Using a tester, check whether the motor is working or not; if it is not working, you will have to disassemble it or make a complete replacement.

How to remove the rear wiper gear motor of a VAZ 2109?

1. Place the rear wiper of the VAZ 2109 in a vertical position and unscrew the fastening nut.
2. Then remove the windshield wiper arm completely.
3. Remove the protective cap on the roller.
4. Use a wrench to unscrew the bracket fastening nut.
5. Next, remove the trunk lining, removing the pistons one by one only in those places that do not allow access to the block with the wires.
6. After removing the upholstery, you will see two blocks, one with wires, the second - a harness block. You need to disconnect them.
7. All that remains is to unscrew the two wiper bolts and remove it from the rear door.

Let's start disassembling the VAZ 2109 windshield wiper itself

1. Remove the rubber ring and washer from the gear housing.
2. After this, remove the locking and sealing rings one by one.
3. Unscrew the screws securing the gearbox cover, and then remove the cover with the bracket.
4. Under the cover you will see a sealing gasket, which also needs to be removed.
5. In the gearbox housing there is a mechanism that drives the wiper - we take it out of the housing.
6. Using a screwdriver, remove the reduction gear.
7. Remove the anchor from the housing.

Now check the mechanism

1. The brushes in the brush holder must move freely; if they become stuck, replace them with new ones.
2. Using a tester, check the performance of the motor. Should be replaced if necessary.
3. Check the reduction gear; if the teeth are severely damaged, replace it with a new one.
4. The thread of the rollers must be intact.
5. Also check the integrity of the rubber parts; if they are severely worn, be sure to replace them with new ones.

Windshield wiper device for VAZ-2108.

The electric motor consists of a stator with permanent magnets and an armature with an elongated shaft, at the end of which a screw (worm) is threaded. On the worm side there is a commutator and a brush assembly. The brush assembly has three brushes, one negative and two positive, located at different angles relative to the commutator. This arrangement provides different speeds of rotation of the armature, necessary to change the frequency of operation of the purifier.

A gearbox consisting of a helical gear meshing with a worm at the end of the armature shaft is attached to the electric motor on the commutator side. The gear is located on a shaft to which a lever system is attached. On the opposite side of the shaft on the gear there is a cam that actuates a movable contact that ensures that the brushes stop in the extreme position.

Recently, a thermal fuse has also been placed in the gearbox to prevent the electric motor from burning out when the brushes jam or freeze. Previously, this fuse was installed on the wiper frame.

The windshield wiper operating modes are switched using the steering column switch, and its operation in intermittent mode is carried out by the wiper relay.

How to turn on the rear wiper on a VAZ 2109

VAZ-2109: The windshield wiper blades do not work. Possible causes of the problem

Windshield wipers (wiper blades) are designed to keep the windshield and rear window clean. In good condition, thanks to the support of the washers, they easily cope with dirt, snow and water. But if the wipers stop working, it is not recommended to continue driving in bad weather. Your safety depends on it. The best thing to do is stop and try to fix them.

In this article we will talk about why the wiper blades on the VAZ-2109 do not work. We will look at the main causes of this problem, as well as how to fix it.

Windshield wipers nine

If you think Windshield wipers VAZ-2109

is not working or not working properly before starting repairs, it will be helpful to learn about the windshield wiper system in general. Therefore, it will be easier to determine the cause of the problem and then fix it.

Wiper. it is a device consisting of a drive (a motor with an extended shaft), a gearbox and a linkage system called a trapezoid. It is she who activates the napkins.

How does a windshield wiper work?

A worm is cut into the front end of the engine rotor, which locks and controls the final drive of the gearbox. When the windshield wiper is turned on, motor voltage is supplied to the vehicle's on-board circuit. In this case, its shaft begins to rotate, activating the gearbox. This, in turn, moves the levers, the ends of which are brought to the surface of the sleeping body panel and connected to the windshield wiper covers. One end of the gearbox shaft is equipped with a special cam, which controls the movable stop contact of the windshield wiper to its extreme position.

Wiper control

The windshield wiper is controlled by a special switch mounted on the steering column of the car. With its help, the wipers not only turn on and off, but can also operate in different modes. This allows you to adjust the windshield wiper speed depending on weather conditions. VAZ-2109 cars have three modes:

• intermittent;
• constant wiper speed;
• permanent high speed wipers.

It often happens that the VAZ-2109 does not operate the windshield wiper in only one of the modes, so it is important to know not only the design features of the windshield wiper, but also the mechanism for controlling its operation.

The intermittent wiper blades are activated in the first (working) and second positions of the lever. Its operation is ensured by relay type 526.3747. It is located in the vehicle's subassembly and is designated "K3" in the electronic circuitry. This relay also controls the windshield wipers and washers.

In the third position, the cleaner operates at a constant speed at low speed. To switch to continuous high-speed cleaning mode, a fourth lever position is provided.

Symptoms of malfunction

To fix a broken brush, let's look at what signs it may have.

Symptoms may include the following:

• when turned on, the device does not respond at all (the relay does not click, the motor does not work);
• the relay works, but the engine does not start;
• both the relay and the motor, but the arms do not move or do not move in the wrong direction;
• The intermittent wiper mode of the VAZ-2109 does not work;
• the engine does not stop intermittently;
• The wipers are slow.

Now let's analyze each of the functions separately from the point of view of possible errors and how to fix them.

The windshield wiper does not respond to switching or switching modes

If you are trying to turn on your windshield wiper blades, but the VAZ-2109 wiper blades are not working, and when you shift the lever you do not hear the relay or the sound of the motor running, the cause may be found in either the switch, relay, or fuses.

Some cars are equipped with a hydraulic headlight leveler, which is used to adjust the headlight angle from the driver's seat depending on the load on the car.

Wiring diagram for wipers on VAZ 21099

If we isolate all the elements of the windshield wipers into a separate diagram, it will look like this:

In addition to the diagram for connecting the wiper block to the wiring harness from the mounting block, here are the contacts of the steering column switch 8, which close when one mode or another is turned on, as well as the addresses of the wires in connectors Ш3 (Х3), Ш1 (Х1) for connecting the harnesses from inside the passenger compartment to the unit and connector Ш11 (Х11) on the outside of the power supply.

If we analyze this diagram, we can draw the following conclusions:

• the first and second speeds of the wipers are turned on without the participation of relay K3 (installed in fuse box 5); that is, if the wipers of the VAZ 21099 only work at high speeds, the relay itself is faulty. The failure of the continuous mode is caused by interruptions in the power supply to the motor brushes “a” and “b” and the lack of contact between terminal 53a and terminals 53 and 53b of the switch;
• For intermittent and short-term operating modes, only the first speed of the gearmotor is used. Therefore, if the wipers operate only at the third speed (mode 5 of the switch), then the reason for the failure is a break in the circuit of the brush “b” (first speed) of the gearmotor.

In addition, the color coding of the wires and the designation of their addresses in the plugs will help you “ring” this or that section of the circuit for a break.

The figure below shows the designation of the steering column switch terminals:

Due to the fact that the design of the switch is quite weak, the reason that the VAZ 21099 wipers do not turn off or work only in one mode may be the destruction of the moving elements inside the assembly. You can check it by checking with a regular probe with a light bulb, using the above diagram.

On the VAZ 21099, not all contacts are activated due to the lack of a rear wiper and washer.

Dimensions

The driver and passenger side brush lengths are different. The difference is small - only 20 mm. If possible, avoid installing brushes of the same length. Otherwise, a path of water will form in the middle of the windshield during rain. Which will lead to a significant deterioration in visibility. The rear window is equipped with a 300 mm long brush.

The rear hemisphere allows for the installation of a brush 400 mm long. In this case, the lower part of the window will not be affected. But you will have to limit the stroke of the brush on the gearbox. To do this, you need to disassemble the motor that drives the brush.

Original articles

It will no longer be possible to find original parts for this car produced by AvtoVAZ. It is only important to note: in the assortment offered by stores, it will not be difficult to choose a high-quality analogue. In the last years of car production, the manufacturer no longer made brushes on its own. Ready-made solutions were purchased from Bosch.

Original articles used back in the Soviet Union:

Replacement options

There are quite a lot of companies involved in the production and sale of various brushes. Including for the VAZ 2109. When choosing, you should give preference to well-established manufacturers. But it is important to remember: there are always many counterfeits of well-known brands. You should carefully inspect the boxes before purchasing. This will avoid purchasing a fake.

All presented brushes are divided into 4 main categories:

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

Frame

Designated as classic. They are distinguished by their low price and simple design. The strength of such products is great. But a serious disadvantage is the poor aerodynamic shape. When air resistance occurs when driving at speeds over 100 km/h, the brush rises slightly above the glass surface. Which leads to a decrease in the contact area. Deterioration in the degree of glass cleaning.

Frameless

Brushes of this type do not have the disadvantages of classic models. They have an optimal aerodynamic shape and look aesthetically pleasing. At the same time easy to install. The only negative: low strength. At the same time, the cost is relatively low.

Hybrid

Hybrid – a design that has all the advantages of classic and frameless brushes. Today this is the best option. Low cost, coupled with low aerodynamic resistance and good cleaning properties, makes their use convenient and effective. The brush itself is made of a single piece of rubber. There is a frame inside. Some modifications are equipped with a spoiler. Which makes the brush even more streamlined.

Winter

Winter wipers are distinguished by their elasticity - even at sub-zero temperatures they clean the glass well. The effect is achieved by adding rubber to the rubber composition. It retains its flexibility regardless of the ambient temperature. As a result, its cleaning qualities do not change in any way.

When choosing new wipers, take into account:

• mode of operation of the vehicle;
• maximum driving speed;
• the region in which the car is located.

If the car is used in the Far North, then it is advisable to purchase winter brushes. Driving at speeds over 100 km/h - the windshield will only be cleaned with the proper aerodynamic shape (frameless, hybrid blades). If you have no experience, you should contact a consultant.

Some drivers purchase several pairs of brushes at once:

• for summer;
• for winter;
• for long trips and highway driving.

It is very comfortable. Allows you to avoid unnecessary expenses. Spare parts are always available.

Technical characteristics of the gearmotor:

The purifier has three operating modes, they are activated by the right steering column switch. Intermittent mode is provided by an electronic relay type 52.3747 or 525.3747 installed in the mounting block. The relay also turns on the low speed wiper motor when the windshield washer is turned on. The relay must ensure that the electric motor is turned on with a frequency of 14±4 cycles per minute at a gearmotor shaft speed of at least 20 min–1, a temperature of (20±5) °C and a supply voltage of 14±0.2 V.

When the cleaner operates at low speed in constant mode, the supply voltage is supplied to diametrically opposed brushes. When the cleaner operates at maximum speed, “+” power is supplied to the brush located on the side.

It is recommended to replace a faulty gearmotor with a new one (cleaning the commutator, limit switch contacts and replacing gears is possible). Bent levers are straightened. If the hinges are worn out, replace them.

The windshield washer consists of a polyethylene reservoir with an electric pump installed on the right side of the engine compartment, washer nozzles located on the hood, and flexible connecting hoses.

The washer is activated by the right steering column switch, and power is supplied to the pump motor and windshield wiper relay, which turns the wiper on at low speed if it has been turned off or was running intermittently. If the pump malfunctions, it is replaced. Clogged nozzles can be blown in the opposite direction or cleaned with fishing line.

The washer solenoid valve in a vertical position (with the fittings down) should operate at a voltage of no more than 8.5 V. The resistance of its winding at 25 °C should be (95 ± 6) Ohms.

Slightly ahead of the sequence of events, so as not to forget, I’ll tell you an epic story about wipers... Everything went its way, birds sang around, the grass turned green and the bright sun was shining... But everything can’t be smooth, especially with the Russian automobile industry)) Trouble happened, my people got sick wipers, at first they started moving slower, then even slower, then very slowly, and when I changed the blades they stopped moving altogether) I scrolled through the Internet up and down and I want to share with you the chronology of actions in such incidents... There are not very many reasons for wiper failure , let's start with the simplicity of actions to solve the problem:

1. The first thing to look at is the fuses and relays, this does not require special knowledge and the waste of time is minimal...

We remove the cover from the mounting block; on the back side, as a rule, there is an arrangement of fuses and relays. If I'm not mistaken, fuses F4 (10A) and F5 (15A), and K3 are the windshield wiper relay... It all depends on what part you have. I would like to note that if the relay is faulty, speed 3 of the wipers should still work... If replacing the relay returned the missing 2 speeds, you don’t have to read any further) At the same time, move the cable to the mounting block (after all, this is the Russian auto industry =) Be sure to inspect the connector connecting the motor to h/i, clean, connect back. It didn’t help - move on... Try connecting the motor directly to the battery, if it works, then the problem is either a broken wire or a burnt track in the installation...

2. The second problem that could happen is a malfunction of the steering column switch...

Here everything is a little more complicated than with fuses... I think everyone can disassemble the trim and remove the steering column switches... Here option 2 is either to change both at once for some aesthetic reasons, or to remove the old ones and ring them.
This is done according to the following scheme: 1st position of the lever - everything is off 2nd position - intermittent operation without fixation - contacts 53e-53,53a-j
3rd position - intermittent operation - contacts
53e-53, 53a-j
4th position - 1st speed - contacts
53a -53
5th position - 2nd speed - contacts
53a-53b
6th position - washer and wiper
53ah-W
There is still no smile on the face - we move on...

3. We dig deeper, we need to determine the problem in the trapezoid or in the motor itself.

We remove the rod from the engine and check whether the trapezoid moves easily - if not, we disassemble, remove, clean, lubricate, put it back, and along the way we make all the AvtoVAZ designers hiccup =)

If it's easy to walk, turn on the wiper motor - it should walk easily and without jerking. If it stops under load, then the problem is solely in it... It threatens to either be replaced or repaired. The prices are steep, to put it mildly)) I have no other options left... I hope I could help in some way =)

If I had known all this before, then at 8 I would have solved all my problems by replacing one relay) But this time I didn’t want to bother and I decided to change everything at once... I bought myself an “original” motor assembled with a trapezoid, it’s better about the price I won’t say anything :DD We drilled into a “not very” warm garage, armed ourselves with the necessary tools and rich Russian language and began... 1. Remove the brushes for convenience -> use a 10mm wrench to unscrew the nuts of the leads, remove them... 2. Pry it up with a flat screwdriver and remove the protective cap - > use a 24mm wrench to unscrew the nuts -> remove the plastic and rubber washers (remember in what order they were installed) 3. Disconnect the wires to the motor and use a 10mm socket to unscrew the bolt where its minus is attached.
This is where the fun begins

Proper operation of the windshield wiper is very important during bad weather. It provides good visibility on the road – the safety of the driver and passengers.

Adjusting the Trapezium Wipers of VAZ 2109

Proper operation of the windshield wiper is very important in bad weather. This provides good visibility on the road. safety of the driver and passenger. Windshield wiper failure is a common problem in cars. The article discusses situations when windshield wiper blades do not work on a VAZ 2109 car, and how to repair windshield wiper blades.

Windshield wiper device

The main purpose of windshield wipers is to remove dirt, rain and snow from the windshield and rear window using blades and washers during inclement weather. If the VAZ windshield wipers do not work, this reduces safety, so it should be renewed as soon as possible.

You need to know your windshield wiper to troubleshoot.

Auto parts for wipers

Its design includes:

• Electric motor;
• lever system (trapezoid);
• Transmission;
• washer motor;
• tank;
• washer pump;
• solenoid valve washer;
• brushes and springs.

In addition, the design of the windshield wiper includes many small parts.

Glass cleaning scheme

Diagram of glass cleaner and washer

The numbers on the diagram indicate the following components: 1. washer motor; 2. electric engine wipers; 3. assembly unit; 4. ignition switch; 5. washer switch unloading relay; K3. windshield wiper relay.

The glass cleaner can operate in three modes. Mode "I" is intermittent. Mode "II" is permanent. In this mode, the brushes move at low speed. Also a permanent mode is mode III. This is different from the previous high speed brush movement. The mode is activated by a switch (video author: Auto Electric HF).

General disadvantages

The main signs of a faulty VAZ 2109 wiper:

• complete stop of the wiper, no lever response;
• brushes do not work intermittently;
• wipers work slowly;
• the movement of the brushes does not correspond to the mode included in the interior.

Troubleshooting methods

If the wipers on a VAZ 2109 do not work, then you can detect and fix the breakdown yourself.

The renovation is taking place in stages:

• first the assembly is disassembled;
• then faults are identified;
• then repair or replacement of faulty parts is carried out;
• At the final stage, the assembly of the unit is performed.

Removed glass cleaner

Dismantling consists of the following sequence of actions:

1. First of all, you need to de-energize the car by removing the negative terminal from the battery.
2. Next, the brush arms are installed in a vertical position, then the fastening nuts are unscrewed. Now they can be removed.
3. Armed with pliers, we pull the levers off the slots, trying not to damage the threads.
4. The plastic protective caps are removed from the slots.
5. Then you need to unscrew the nuts securing the bracket and you can remove them along with the washers that are located under them.
6. Next, in the engine compartment, you need to disconnect the wire block that serves to power the windshield wiper motor.
7. At the next stage, it is necessary to move the heater fan so that it does not interfere with removing the mechanism. To do this, unscrew the fastening screws.
8. We remove the cover from the mounting block and dismantle all the relays located in it, since they will interfere with further work.
9. Unscrew the lower bolt securing the purifier bracket.
10. Then we remove the plastic wire holder through the gap in the body and remove it so as not to lose it.
11. We remove the device rollers through the holes in the body. Then, slightly lifting and moving the windshield wiper with the motor up and to the side, remove the assembly.

Next, the mechanism is completely disassembled. A visual inspection of all parts is carried out, including the wipers of the VAZ 2109. A broken brush can be replaced, but it is better to change both. If mechanical damage is detected or parts are severely worn, they need to be replaced.

After all faults have been detected and eliminated, we reassemble the unit in the reverse order and install it in its original place. After the repair, it is necessary to connect the negative terminal on the battery and check the operation of the windshield wiper.

In this way, repairs and modifications to the VAZ 21099 glass cleaner are carried out with your own hands. The process is long and tedious, but can be done independently. This will make it possible to save money on expensive repairs at a service station.

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:

1. Damage to system levers. Even a slight change in the shape of these parts can affect the speed of the mechanism.
2. Faulty power cords. If there is not enough electricity supplied to the system, it is no wonder that it will slow down.
3. 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.
4. 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.
5. 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.

Repair

To troubleshoot problems with the wipers on your VAZ 2109, it is not at all necessary to contact a service station. The work can be done with your own hands, saving a decent amount of money.

Repair consists of performing several operations:

• Disassembling the unit;
• Troubleshooting;
• Eliminating the causes of purifier failures;
• Reassembly.

Dismantling

The first step is to learn how to remove windshield wipers. This will give you access to the device and all its components.

It is enough to follow the specified sequence of actions and first familiarize yourself with the wiper diagram in order to do everything correctly.

Scheme

1. First, disconnect the negative terminal of the battery to de-energize the car.
2. Remove the brush arms by moving them to a vertical position and unscrewing the fastening nuts. Unscrew the nuts carefully so as not to push the lever out. Otherwise, under the action of the spring, it will fly into the glass and break it.
3. By unscrewing the fasteners, the levers can be removed. It is not always possible to do this manually, so arm yourself with pliers. Be careful not to damage the threaded area. To avoid this, screw the nut back onto the splines, but not completely.
4. Remove the protective caps made of plastic from the slots on each side.
5. Unscrew the upper mounting nuts with the bracket and remove them. Under them there are rubber washers, which are also dismantled.
6. Lift the hood and disconnect the wiring harness that powers the wiper motor.

1. Unscrew the heater fan mounting screws and move it slightly to the side. This way, when dismantling the purifier, it will not interfere with you.
2. Remove the cover from the relay and fuse box. You need to remove not only the wiper relay, but also everything else. Otherwise, they will interfere with your further processes.
3. Unscrew the lower fastening nut of the mechanism, remove the plastic holder of the wiring harness from the electric motor from the hole in the car body. Now you can remove the holder so that it does not get lost during the repair.
4. All that remains is to push the mechanism roller inside, then lift the electric motor and the windshield wiper mechanism slightly up and to the side. This way you can easily remove the node.

After completely disassembling the unit, you can check the condition of each wiper mechanism and determine the cause of any malfunctions.

Device

Checking the status of elements

By disassembling the design of the wipers on your VAZ 2109, you can identify the damaged components that led to the problem. We will tell you exactly how to find the culprits.

Checking the fuse box
If the windshield wiper fails, first check to see if the fuse has blown and if everything is in order with the relays that are responsible for the operation of this unit. Often complex repairs are not required; it is enough to simply remove the burnt-out fuse element and replace it with a new one.

In some cases, a blown fuse indicates something more than just a broken fuse. What exactly causes the fuse to break is an important question. Therefore, it is recommended to disassemble the wipers, check the condition of all components and figure out what was the real reason for the failure of the brushes on the VAZ 2109.

Motor repair

Many people think that replacing the motor with a similar one from a foreign car can solve the problem with the slow operation of the wipers, but in fact, it is often enough just to clean and lubricate the “original” engine.

If the speed of operation causes complaints, then it is necessary to check how easily the armature rotates: if movement is difficult, damage or excessive wear of the brushes should be suspected. They are easy to replace with new ones.

Cleaning the collector will also help - this will require fine sandpaper. The need for this procedure is said:

• visible contamination;
• noticeable scratches;
• grooves on the metal.

It will be necessary to replace the armature or gearbox along with the complete motor if the manifold is too worn or burnt.

Adjusting the operating speed is necessary if the windshield wipers operate too slowly. This is facilitated by:

• incorrect (too tight) lubrication;
• gear wear;
• rod deformation

Work on disassembling the rear wiper of a VAZ 2109

— The gear housing has a rubber ring and a washer, remove them.

— Also, the windshield wiper mechanism has a retaining ring and an O-ring. First remove the first one, then the washer, and then the o-ring.

— Now you need to remove the screws that secure the gearbox cover, and then remove the cover along with the bracket. Then remove this bracket from the cover.

— You will see a sealing gasket, remove it.

— There is a carrier in the gearbox housing, remove it.

— Also take out the gearbox. To do this, use a screwdriver.

— Now you need to remove the anchor from the housing. To do this, unscrew the nuts and lower the engine housing.
