Lada Granta wipers do not work: main reasons

Why might the wipers not work?

The most basic reasons why wipers on a Lada Granta may not work.

1. The steering column switch for the wiper operation mode is faulty.
2. The contact relay is faulty.
3. The fuse is faulty.
4. The wiper mechanism (motor, ramp) is faulty.
5. Circuit break.

Let's consider each of these reasons separately.

Fuse blown

If, after replacing the fuse with a known good one, the wipers still do not work, then check the contact relay. The check is the same, it is replaced with a known good one.

Incorrect operation of the steering column switch

The car's wipers only work when the ignition is on. Therefore, if you try to turn on the windshield wiper with the ignition off and nothing happens, then this is not a breakdown!

Steering column switch for car wiper operation modes

If any of the modes does not work, then most likely the steering column switch has failed.

If, after replacing the steering column switch with a working one, the wipers still do not work, then you need to check whether voltage is coming to the fuse connector.

If there is voltage at the fuse connector, then the steering column switch is working.

Damage to the wiper mechanism

Often the nut 13 is unscrewed

The inspection begins with a visual inspection of the mechanism and checking the tightness of the threaded connections. It is not a rare situation when the nut on the output shaft of the wiper mechanism gearbox, which holds the trapezoid drive crank, is not tightened. Next, they try to apply voltage to the motor directly from the battery, this will help to find out whether the wiper motor is working properly.

No voltage on the motor

If after checking the relay, fuses and switch the wipers still do not work, then check the voltage at the motor terminals. If it is missing, then there is a break in the circuit somewhere.

What to do? Where to look?

If you can hear the sound of the motor-gearbox, then it is definitely working. If it works, but the brushes do not move, then there is a break somewhere in the rods or contact elements.

1. Most often, a break or loss of “contact” of the trapezoid occurs due to wear of the teeth on the drive shaft of the gearmotor. In other words, the motor works, but does not engage the windshield wiper trapezoid. There is nothing left to do but replace the drive part (by disassembling the gear motor and replacing the spline part). But, if you don’t find this part (rarely found on sale), then either look for a used motor or replace it with a new one.
2. The second cause of the malfunction may be a loose nut securing the trapezoid mechanism to the motor (tighten the nut). This malfunction can be immediately noticed if you look into the trapezoid compartment.

Perhaps these are the two most main reasons for this malfunction. True, there are cases when the rods fly off the crank or the splines on the wiper arm drive itself wear out (photo). All that remains is to either look for a spare part or change the trapezoid assembly.

If you have not found the answer to your question, read other possible malfunctions of the wipers in the article: “The wipers do not work. What to do?"

You shouldn’t put off until tomorrow the question of how the wipers work, because... The comfort and safety of your ride depends on this.

Wipers do not clean well

A couple of times I encountered non-working wipers on Grant. Both times the fuse blew. There's a weak spot somewhere.

Alexey “technical specialist”:

Most likely, the increased load is caused by the wiper motor; it may be faulty.

I watched your video and now I understand why my wipers either work or slow down. I already contacted the service twice, but after the repair the same problem happened again. Perhaps this is a fuse? I'll go change it.

Alexey “technical specialist”:

Are they lying? If the fuse breaks, the wipers do not work at all, since there is no contact. Most likely it is the wiper relay. Start checking with them.

problem with the switch

Today I noticed that the wipers somehow began to work more slowly. What do you think this might be connected with?

dirt has gotten on the wiper shafts themselves, carefully disassemble, remove dirt and anoint

The motor on my driver's side keeps breaking down.

I agree with Roman, the only reason electrics fail is that the shaft bushings often become clogged, hence slow rotation, braking, and as a result, overheating of the engine, increased current and blown fuse

What is the reason for sticking wipers?

The wipers do not work in the first mode. What could it be?

In cold weather, when the ignition is turned on, the wipers automatically turn on. What could it be

Hello everyone, today I would like to talk about why the wipers on the Lada Granta do not work, and consider the main reasons for this malfunction.

As you know, the Lada Granta is not equipped with the most expensive wipers, or rather, windshield wipers. And the first thing drivers encounter is the whistling sound of their wipers. And this happens because the rubber bands of the wipers simply harden especially noticeably in winter. The solution is to replace them with more expensive ones, but in general it is advisable to change the wiper blades at least once a year.

The next malfunction associated with wipers is incorrect installation of the brush leads. As a result, one brush does not reach, and the second, on the contrary, oversteps the boundaries of its working area. Solved by proper installation.

If the wipers do not work at all, then you need to start troubleshooting with fuse F 4 at 20A. The wiper fuse on the grant is located in the mounting block to the left of the steering wheel. If the fuse is blown, then it should be replaced, but if it is intact, then you need to check relay K 6. You can check the relay by replacing it with a working one of the same type.

The next reason why the windshield wipers do not work is a nut that has unscrewed from the output shaft of the gearbox.

If the wipers only work in one position, then the microcircuit located inside relay K 6 may have failed. And if the wipers do not work at first or second speed, then the commutator brushes in the electric motor may be stuck.

Well, that's all, we looked at the main reasons why the windshield wipers do not work on a Lada Granta car.

Incorrect operation of the wipers is included in the list of five malfunctions for which any operation of the vehicle is prohibited, even driving to the repair site. Therefore, you should take the issues of repair and diagnostics of the wiper mechanism very seriously.

Why might the wipers not work?

The most basic reasons why wipers on a Lada Granta may not work.

1. The steering column switch for the wiper operation mode is faulty.
2. The contact relay is faulty.
3. The fuse is faulty.
4. The wiper mechanism (motor, ramp) is faulty.
5. Circuit break.

Let's consider each of these reasons separately.

Fuse blown

The most common situation is a blown fuse. Diagnostics should begin with it; to do this, replace the fuse with another one from the mounting block. The number of the windshield wiper fuse in the mounting block is F4. Detailed diagram of the mounting block is here.

Next, they try to apply voltage to the motor directly from the battery, this will help to find out whether the wiper motor is working properly.

No voltage on the motor

If after checking the relay, fuses and switch the wipers still do not work, then check the voltage at the motor terminals. If it is missing, then there is a break in the circuit somewhere.

The standard windshield wiper relay (526.3747-03) for Lada Granta, Kalina or Priora cars provides for 4 sweeps of the wipers after washing the windshield. For high-quality cleaning, two strokes are enough, and the next two strokes pass through dry glass with a squeak. The problem can be solved by modifying the wiper relay, which will reduce the number of strokes of the windshield wiper blades.

The wipers sometimes work, sometimes they don't.

The serviceability of windshield wipers directly affects traffic safety.
It happens that the wipers refuse to work in some mode or do not turn on at all. Why? Windshield wipers of all cars have at least two operating modes - intermittent and constant. For convenience, this list also includes additional options, for example, a slow speed of a constant mode, one stroke for quickly cleaning the glass, and so on, right down to adjusting the pause between strokes.

Technically, this is all quite easy to implement: the intermittent mode creates an electronic or mechanical relay paired with a switch inside the electric motor, and with the constant movement of the brushes, voltage is constantly supplied to the same electric motor. Let's look at typical windshield wiper malfunctions and methods for finding them.

Wipers do not work intermittently

As mentioned above, the breaker relay is responsible for the intermittent operation of the wipers. It can be mechanical (on older cars) or electronic. Accordingly, if the wipers work in constant mode (which is created by bypassing this relay) and do not work in intermittent mode, there is a reason to check the relay.

However, before starting the test, you need to make sure that the relay is receiving voltage from the steering column switch set to the intermittent mode position. It may well be that the malfunction lies in it, and not in the relay. In the steering column switch, in particular, the corresponding contact may oxidize or the wire connecting it to the relay may break.

Based on this, you need to find a wiring diagram for the wipers on your car and check whether current flows from the switch to the relay. If not, look at the switch. If there is current, check the relay.

Wipers do not work constantly

When the windshield wipers work great in intermittent mode, but refuse to move constantly, you can immediately talk about a malfunction in the same steering column switch or problems in the area between it and the wiper motor. Simply put, the voltage from the switch is not supplied to the motor. You also need to check this electrical circuit with a multimeter or a test light to make sure that all terminals are clean and securely fastened.

The wipers don't turn on at all

If the windshield wipers do not react at all to the steering column switch, you should start with a classic check - make sure the fuse is intact. If it is intact, you need to check the steering column switch for voltage supply to it and correct closure of the contacts inside. Most likely, there will be no voltage on it.

A special case of complete failure of the wipers is when they are blocked by something. This could be a wrench left under the hood, a rag, or frozen wiper blades (read what to do if your wiper blades are frozen). For such situations, a special fuse is usually installed in windshield wiper systems. This device saves the wiper motor from overheating and failure by turning off the power. In the simplest case, such a fuse is a heat-sensitive plate that, when heated, changes shape and opens the contact. After turning off the voltage, it returns to its previous position and you can use the device (in this case, the wipers) again.

When the wipers are blocked, they usually still move at least a little from their “parking” position. Therefore, if there is still a slight reaction to switching on, check the freedom of movement of the brushes and trapezoid. Most importantly, do this with the wipers off.

! Accidental activation of the windshield wiper can cause serious injury!

The pause between strokes is not adjustable

If your car has the ability to adjust the pause between wiper sweeps and this function stops working, the adjusting resistor is most likely to blame. This part, depending on the rotation of the knob (or wheel), changes the resistance value in the wiper relay circuit, due to which it is possible to adjust the pause. This resistor should be replaced.

Wipers don't work

Undoubtedly, if the windshield wipers , driving the car becomes dangerous in bad weather. In this article we will discuss 7 reasons why wipers may stop working. First, we will discuss simple reasons, then we will move on to more complex ones.

1) The fuse has blown

A fuse is a weak element in a circuit for the purpose of protecting other devices and appliances. In this case, the fuse protects the wiper motor.

In any case, it is better to start troubleshooting with fuses. Since a blown fuse is a fairly common reason why wipers stop working.

In order to find out the location of the fuse, you need to look at the owner's manual for your specific vehicle.

2) Malfunction in wiring and contacts

The next thing you should pay attention to is the integrity of the wiring, as well as the contacts in the connectors. Over time, the contacts oxidize and this may affect the operation of the wipers. Oxidized contacts must be cleaned.

3) Relay is faulty

A relay malfunction can be detected by the intermittent wipers not working. If the wipers work properly in slow and fast mode, but do not work in intermittent mode, then the wiper relay needs to be replaced.

4) Faulty wiper fastening

Over time, the wiper mount may become loose, causing the wipers to stop moving. Because the wiper motor cannot move the position of a weakened wiper. In order to correct the situation, you need to tighten the nut of the loose wiper.

5) The wiper control unit is faulty

Thanks to the control unit, it is possible to switch the operating mode of the wipers. A common reason for the steering wiper switch not working is oxidation of the contacts. If all the windshield wiper elements work, but the wipers still refuse to work. Then you will have to replace the wiper control unit.

6) The wiper motor is faulty

If the wiper motor is faulty, the wipers will stop moving altogether, which is not surprising. In order to detect signs of motor life, it is necessary to check the voltage in the electric motor connector. The voltage of the wiper motor should be the same as that of the battery. If so, that means he's alive.

Over time, the brushes in the wiper motor wear out and can be replaced. If the winding burns out, it’s easier to buy a new wiper motor. Since replacing the winding does not make sense.

7) Trapezoid is faulty

The trapezoid consists of rods and levers thanks to which movement is transmitted from the motor to the wiper arms. It rarely fails. Often the leads themselves break down due to the flimsy design of the slots. Therefore, a small force in the opposite direction can break them. In this case, the leashes will have to be replaced.

For Lada Granta, Kalina, Priora

It is worth noting that on sale you can find a wiper relay with advanced capabilities:

• There is a pause adjustment, that is, you can set any time between sweeps of the wipers;
• Three strokes after the washer, instead of four (there is no problem with the wipers squeaking on the glass);
• After the washer, the first stroke is delayed.

However, replacing a resistor in a relay yourself will cost only 5 rubles, and a functional relay will be 70-100 times more expensive.

For Lada Granta FL

The Lada Granta FL (updated family) has a 66.3787 relay installed, which differs from the previous ones in that SMD resistors are soldered into it. They are very small, so re-soldering them with your own hands will not be so easy. To replace, you will need an SMD resistor number 183 (18 kOhm), and they can solder it at a phone repair service for 50 rubles. It is necessary to replace the resistor 3922 (39 kOhm) with the 183rd one. After modification there will be 2 sweeps of the wipers, not 4. Author Stanislav Ivanov

Let us remind you that you can improve windshield cleaning by replacing the standard jets (washer nozzles) with fan jets.

Most fuses are located in the mounting block inside the car. The serial numbers of fuses and relays are indicated on the housing of the mounting block. The purpose of the relay and the circuits protected by fuses are indicated by symbols on the inside of the instrument panel trim, which covers the location where the fuses are installed. The current strength for the fuses is also indicated there. Additional relays can be installed to the left of the Lada Granta mounting block.

Cars VAZ 2190, VAZ 2191 - 2011, 2012, 2013, 2014, 2015.

Cars Lada Granta Liftback, Granta Luxury, Granta Standard, Granta Norma were also considered.

Where is the mounting block located on the grant?

In the cabin. The fuse and relay mounting block is installed in the instrument panel on the left side.

1. Pull and remove the instrument panel trim

2. Using the number on the inside of the trim, we find the fuse for the faulty circuit.

3. Using tweezers, remove the faulty fuse

Sometimes the fuse thread remains intact, while its connection inside the fuse is broken. It is impossible to visually determine such a malfunction. In this case, you can assess the condition of the fuse using an ohmmeter or a test lamp.

2 times for me! Under warranty, the motor and trapezoid were replaced within a year of owning the car. They said the engine was jammed. So now the problem is that the intermittent mode does not always work. Sometimes it works, sometimes it doesn’t, position 4 (the fastest) is always on. The problem most often appears after parking on the street. I changed the relay - it doesn't help. What's with the wipers on grants? Or maybe I'm just the lucky one. Fed up! I think maybe the steering column switch needs to be changed?

The main symptoms of failure of the windshield wiper motor or trapezoid

The windshield wiper system includes two main elements that drive the blades - a gear motor and a so-called trapezoid. If, when the right steering column switch is installed in the appropriate position, the brushes do not move, this may indicate either a malfunction of the motor electric motor or a jammed trapezoid.

As a rule, when the shafts and hinges of the mechanism are severely oxidized, the windshield wipers do not stop working “at once.” Up to this point, there is a slowdown in the speed of movement of the brushes and their wedging in various positions. This is a sufficient reason to think about taking appropriate preventive measures (see the article Prevention of the trapezoid and windshield wiper motor) or replace the trapezoid and windshield wiper motor.

The cause of the malfunction may also be damage to the contacts or a short circuit in the motor caused by moisture getting inside. Usually in such a case the fuse responsible for the wipers blows out. Please note that the windshield washer continues to function in this case. Another common cause is the formation of plaque and rust on the engine shaft or joints as a result of corrosion.

Types of wiper breakdowns

Windshield wiper failures can be divided into two types: electrical and mechanical. Each type of breakdown is complex in its own way and makes it difficult to repair in the field. In some cases, it is necessary to remove many parts to get to the source of the problem.

The most common wiper failures:

• Fuse blown;
• Windshield wiper motor winding burnout;
• Wiper switch malfunction;
• Burnt out wiper relay;
• Breakdown of wiper splines;
• Mechanism failure or jamming;
• Gearbox jamming;

K1 - heater fan relay

K2 - power window relay. If they do not work, also check fuse F2; if this does not help, then the problem may be in the control unit.

K3 - starter relay. If it does not work (does not turn) and this relay is working, check the battery charge level. It could also be a problem with the retractor or the ignition switch and its contacts.

K4 - ignition switch terminal 15 relay

K5 - turn signal and hazard warning relay. If the turn signals come on and do not turn off, this relay may be shorted. Also check fuse F3 (emergency mode).

K6 - windshield wiper relay. Check also fuse F4.

K7 - high beam relay. Also check fuses F14 and F15 and the lamps themselves.

K8 - horn relay. Also check fuse F20, signal switch contacts on the steering wheel.

K9 - low beam relay. Also check fuses F12 and F13 and the lamps themselves.

K10 - rear window heating relay. If the heating does not work, the problem may be in fuse F8.

Step-by-step instructions for replacing wipers yourself

Front

1. We place the car on a level platform, squeeze the handbrake, turn off the engine;
2. Using a “10” wrench, we unscrew the nuts on the rods of the glass holders one by one, and remove the brushes;
3. We carry out preventive maintenance of splines, inspect their condition and integrity, and make a decision on the advisability of replacement;
4. install new cleaners, screw the nuts again.

Rear

We change the Grant liftback rear wiper according to a similar scenario:

1. fold back the plastic protective cap at the base of the purifier mount;
2. unscrew the nut to “10”;
3. We remove the entire product, replace it with a new one, and screw the nut again.

Devices for diagnostics of electrical equipment

The set of basic diagnostic instruments includes a circuit tester or voltmeter (although it is quite possible to use a banal 12-volt test lamp equipped with a set of connecting wires). If available, you can use an open circuit indicator, which includes a lamp, an independent power source and connecting wires.

In addition, you should always carry a set of cables in your car to start the engine from an alternative source (usually the battery of another car). These wires are equipped with alligator clips.

It would be a good idea to have an electrical circuit breaker, since this equipment can be used to connect circuit elements and bypass electrical equipment during diagnostics.

Symbols in the drawings

The Lada Granta car has been produced since 2022. This modern car has many of the latest instruments and electronics. All this ensures maximum safety and comfort for the driver. The AvtoVAZ corporation produces 3 types of modifications of the Lada Granta: Standard, Norma, Lux. The connection diagrams for the Norm and Standard trim levels are the same, but for the luxury version they are different.

Electrical wiring consists of a large number of bundles. The drawings contain symbols and serial numbers of on-board network devices. The connection of elements to each other is shown by lines. For greater clarity, the lines vary in color. The wires are combined into bundles. The harnesses connect the blocks using detachable plugs.

The reader must study the operating principle of individual electronic control units and instruments on his own. Simple malfunctions will not create any special problems when repairing or replacing spare parts. In the event of a breakdown of a complex electronic unit, you will have to contact service. There is no need to remember by heart all the details of installing parts. It is advisable for the driver to understand the layout of the drawing and clearly know the locations of the most important devices and electrical wiring.

Tips for motorists

Although the Lada Granta belongs to the latest generation of passenger cars produced by the VAZ automobile plant, it is equipped with the cheapest rubber wiper blades. Therefore, the first problems that the owners of these cars encounter is the ear-piercing sound that the wipers make when moving across the windshield, when they are turned on together with the washer.

This happens due to the fact that the rubber bands of the brushes harden (especially in cold weather) and begin to move along the dry glass before the “anti-freeze” or water begins to flow onto it. This problem can be eliminated by installing, instead of the standard Bosch ECO economy class brushes, measuring 600 and 400 millimeters, more expensive Champion Aerovantage or Bosch Aero Twin brushes. Then the interior of the Lada Granta (VAZ-2190) will become much quieter when the windshield wiper is operating. Yes, and you need to change the brushes at least once a year, before the start of the autumn operation of the car.

The second problem that owners of Lada Granta cars face is the incorrect installation of the wiper arms, as a result of which, when they are turned on, the left brush hits the left pillar of the car, and the right one, when the windshield wiper is turned off, slightly does not reach the parking spot and when the wipers are turned on at first goes down and only then goes up. This malfunction can be eliminated by removing the wiper arms and then reinstalling them by turning them at a slight angle counterclockwise.

If the wipers do not turn on in any of the operating modes, then troubleshooting begins by checking fuse F4 (20A). You can find it by opening the cover of the mounting block, which is located in the front panel, to the left of the steering column. If this fuse has not blown, then, in the same place, you will need to check the functionality of relay K6 (left row, top large), through which power is supplied to the wiper gear motor. We check the relay by replacing it with the same one, but known to be good. In addition, a mechanical malfunction is also possible due to the unscrewing of the nut on the output shaft of the gearbox, with which the trapezoid drive crank is secured.

If the wipers refuse to work in only one intermittent mode, then when troubleshooting, we can assume that the microcircuit located inside the K6 relay, with the help of which the windshield wiper blades pause their operation, has failed. And the refusal of the wipers to work at first or second speed may be due to the freezing of one of the three commutator brushes of the electric motor of the gearmotor.

Incorrect operation of the wipers is included in the list of five malfunctions for which any operation of the vehicle is prohibited, even driving to the repair site. Therefore, you should take the issues of repair and diagnostics of the wiper mechanism very seriously.

Lada Granta brush size - Car repair and maintenance

With the arrival of the autumn-winter period, the driver faces many problems: checking the technical condition of the engine, switching to winter tires, protecting the body from corrosion. But the most important task is to ensure good visibility. Snow, rain, slush - all this settles on the windshield, and if the wipers cannot cope with cleaning, then driving turns into complete torture.

Owners of VAZ family cars can choose from a wide range of windshield wiper blades. Along with classic frame wipers, frameless wipers, which practically do not freeze to the glass, are also in great demand today. In order for the brush to clean the glass surface well, it is made of frost-resistant rubber on a graphite base.

It is also important to choose the right size brushes. If you choose larger or smaller brushes, this can lead to the fact that they will cling to each other, knock on the racks, and uncleaned streaks will remain on the glass. Size information is indicated in the catalogue.

Let's try to figure out what size windshield wiper blade is needed for a particular VAZ model.

Lada – VAZ 2101 – VAZ (LADA) 210

Zhiguli is the first name that many still use. This generation is considered to be a VAZ classic. Compact sedans and station wagons were produced with rear-wheel drive, and the visual difference between these models was the shape of the headlights: round (VAZ 2101 and 2102), dual (2103, 2106), rectangular (2104, 2105, 2107).

The dimensions of the windshield and rear window are the same for all these models; the recommended size of the windshield wiper blades on both the driver and passenger sides is 330 millimeters. However, as many car enthusiasts note, larger brushes - 350 millimeters - are quite suitable here.

Windshield wiper drive device

The wipers are driven by a small DC electric motor, which is equipped with a built-in gearbox.

Three brushes are installed in the motor armature, with the help of which three modes of operation of the entire system are provided. In addition, the electrical circuit for controlling the operation of the windshield wipers includes:

• steering column switch for operating modes;
• relay K2 type 524.3747, which includes intermittent operation;
• additional relay;
• limit switch;
• bimetallic fuse;

The bimetallic fuse and limit switch are located in the electric motor gearbox, and all other circuit elements are located in the mounting block installed in the engine compartment of the car. All elements of the electrical circuit diagram are connected to each other using wires and mounting blocks.
