Most windshield wiper motors have three operating modes, but only two speeds: 1. low speed, with pauses; 2. low speed, without pauses; 3. high speed, without pauses.
On the viburnum, the motor began to stall in all three modes. You will need to throw a good mass onto the body...
The main point of the article is that the motor is transferred to a faster operating mode by: - supplying voltage to it directly from the battery - using high speed in all modes. That is, it will be like this: 1. high speed, with pauses; 2. high speed, without pauses. It is not necessary to connect the third mode - there is no difference with the second in this case)
Only the wiring in viburnum has some differences:
For some reason I couldn’t immediately find a similar circuit for the viburnum, so I thought about it and came up with three implementation options: 1st option: we transfer the wire from the first contact to the second wire from the second contact, we isolate it (or we connect it together with the first one, in one place - so that the 3rd mode works) we don’t touch the third contact; on the fourth, through a regular 4-pin relay, we hang up “+ battery”; we control the relay with the wire that came here (“+” from the ignition through the fuse in the CN) on the fifth, we throw ground on the battery; 2nd option: different from the first in that we connect “+ battery” to the second contact via a 4-pin relay, controlled by a wire from the first contact (or two at once) 3rd option: differs from the third in that, by analogy with the original modification, a 5-pin relay is hung on the second contact, which, depending on the presence/absence of voltage on the control wire, will send “+ battery” / “- battery”, but I don’t see the point in this...
Comrades, if you have already made or seen similar schemes for viburnum, then do not let me invent another bicycle), but just tell me how to do it correctly)) I will also be happy to hear your opinions on this matter and which option to choose!
Structurally, the windshield wiper of a Lada Kalina car consists of an electric motor, levers, brushes and hinges.
The electric motor is three-brush, with excitation from permanent magnets, two-speed.
To protect against overloads, a thermobimetallic fuse is installed.
To reduce radio interference, a capacitor and inductor are installed. A faulty gear motor is best replaced.
The wipers stopped working - we find out and eliminate the cause
Poor quality work of any component and element of your car is not just discomfort during the trip, but also a certain irritating factor. Every time you have to deal with the fact that some piece of technology does not work in a decent way and does not offer a high enough quality of functioning. This is especially difficult for idealists, for whom everything should work at the highest level and without problems. One of the most annoying problems is the failure of the wipers. If the windshield wipers stop working, wave randomly, or stop when the control knob is turned off right in the middle of the glass, you should think about possible problems. Here we should highlight several main components that can break. Trapezoid, wiper fuse, intermittent wiper relay, power handle and other elements.
You can find the cause yourself, or also seek help from specialized forums where similar problems are discussed. Often on forums you will find the same symptoms of a problem and you can easily repair your car. If the wipers stop working, you will have to do something quickly. Otherwise, you will have to experience significant difficulties when traveling in rainy or simply wet weather. In winter, the inability to clean the glass from sticking dirt and constantly sticking snow will simply not allow you to drive normally. You will have to stop every two minutes and clean the windshield. Let's look at the most common problems with wipers in modern cars.
Trapezoid - the mechanism for direct operation of the wipers
One of the most complex mechanisms in the wiper system kit is the trapezoid. Today, no car manufacturer has such a reliable wiper drive mechanism to guarantee long-term operation of the device. Banal jamming of brushes or excessive emphasis on the glass, improper activation of the wipers, freezing to the glass in winter - all these reasons can be detrimental to the trapezoid. Among the possibilities for restoring this mechanism, it is worth highlighting only a few possible steps:
- purchasing a new trapezoid is often the best step for domestic cars, in which the wiper mechanism costs about 1000-1500 rubles;
- for foreign cars, purchasing a new trapezoid will cost exorbitant amounts of money, so in this case, repairs should be made and broken parts restored;
- Often the bushings and tips in trapezoids fail, which are often plastic and are terribly resistant to frost, so they can simply be replaced;
- if it is not easy to find a repair kit for a trapezoid for your car, you can try installing bushings and other parts from other cars of a similar class;
- Direct replacement of the trapezoid is necessary if even repair work does not eliminate the problem, or after repair the mechanism begins to tap during operation.
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.

Measuring the length of the brushes
In order for the wipers to clear the windshield from one edge to the other, it is important to choose the right length. If your car has factory wipers, just measure them with a tape measure.
Take the time to measure both wipers, as some car models have different lengths. Typically, the driver's side has a longer brush. If the lengths are different, you will have to buy windshield wipers individually of different sizes. They are the same for many models. For example, the wipers on the Lada Priora are both 51 cm long. You can buy a set of two pieces. By the way, manufacturers indicate the length in centimeters and inches. For example, 17 inches is 43 cm.
What to do if your car has non-factory wipers? This happens when the previous owner of the car installed products that are not suitable in size. For example, if they are too long, then the edge of the rubber gets on the body and rides up - the brush does not fully adhere to the glass and does not clean it at all. And there are also short rubber bands that do not reach the edges of the windshield - dirty stains remain there and dry out with a gray frame. In such cases, it is better to find out the factory parameters of the brushes.
Based on the most popular requests from car enthusiasts, we have compiled two tables in which we have collected examples of car models with recommended parameters for windshield wiper blades. For convenience, we divided them into Russian-made cars and foreign cars.

Are the rods the wiper arms or the leash?
Do I hit the brushes on the counter? ¶
Well then everything is clear.
It’s just that before replacing, you should have noticed the position of the gearbox shaft on the trapezoid body, you didn’t do that, and that’s why this shit happened now ¶
Replacement of Lada Granta windshield wiper, windshield wipers, wiper motor
The Grant is equipped with a windshield cleaner and washer.
The windshield wiper consists of a gear motor with rods and two levers with brushes. The supply voltage is supplied to the electric motor of the gearmotor through an additional relay when the ignition is turned on. To protect the gearmotor from overloads, a bimetallic fuse is built into its internal circuit.
To supply washer fluid to the windshield, two washer nozzles are installed on the hood. The liquid is supplied to them by an electric pump through an elastic tube from the windshield washer reservoir mounted on the right mudguard in the engine compartment. The pump is installed on the wall of the tank.
In winter, a special antifreeze liquid must be filled into the windshield washer reservoir.
1. Prepare the car for work and disconnect the terminal from the negative terminal of the battery
2. Using a screwdriver, remove the plug from the windshield wiper arm.
3. Using a 13 mm socket wrench, unscrew the nut securing the windshield wiper arm and remove the arm.
If the lever sits tightly on the shaft splines, then in order not to bend the shaft, place a nut on the threads and use sliding pliers to press the lever off the shaft.
4. Similarly, remove the second windshield wiper arm.
5. Remove the air intake grille
6. Release the holder of the connection block of the windshield wiper gear motor.
7. Disconnect the windshield wiper wiring harness block from the vehicle's on-board network.
8. Using a 10 mm socket wrench, unscrew two bolts 1 and nut 2 securing the windshield wiper.
9. Carefully remove the glass cleaner from the air supply box.
If the windshield wiper is new or has been repaired, the arms should be installed last. Before installing the arms, connect the windshield wiper to the vehicle's on-board power supply and turn on the intermittent operation mode. Once the windshield wiper has completed a full cycle and stops, turn it off. And after that, set the levers in the lower position of the glass. If you cannot install the arms so that the windshield wiper works correctly, you should rearrange the crank on the gearmotor shaft (see below, “Windshield wiper - replacing the gearmotor.”
Lada Kalina Hatchback -=First car=- › Logbook › The wipers do not work. Problem with gear motor
Hello everyone! I haven’t visited Drive2 for a very long time. I confess, it’s my fault (Several changes have been made to the machine in a few months =) I will write about everything in more detail in separate blog articles.
So, a serious problem suddenly overtook me. I was driving along the highway, it was raining, I turn on the wipers, they do one cycle and freeze forever... With an astonished look, I try to revive the wipers, but they are silent. I pull over to the side of the road, the first thing I do is check the transmission - everything is ok. I open the hood, visually the rack and the motor are in perfect order... thoughtfully tugging at the contacts near the engine, I took out a cloth, wiped the glass and drove quietly to my destination. I’ll tell you honestly, friends, driving in the rain with non-working windshield wipers is an extreme thing))) God forbid, someone should experience this for themselves.
Old windshield wiper motor
When I arrived home, the first thing I did was contact an electrician. He took the electric motor, simply disassembled it, reassembled it and, connecting it to power, saw that it was alive. I happily put it in its rightful place and went about my business. The next day it rains again. I turn on the wipers, they work very slowly, do 2 cycles and die again. This time I already knew roughly what the problem was, so I didn’t stop, and having already practiced extreme driving without wipers in the rain, I went to an electrician. He was again “glad” to see me with a gear motor in my hands. He took it apart again, replaced all the brushes, cleaned the contacts and the engine came to life again. When the electrician returned this engine to me, he said the phrase: “If it dies again, it’s better to buy a new one.” Well, the man looked at nothing - after 2 weeks the motor died again. It was decided to replace this piece of hardware.
New gear motor, which, unfortunately, did not fit.
I arrive at the local Phaeton auto parts store. I’m buying a gear motor for Kalina for 1,900 rubles, the toad, of course, is choking, but there’s nothing to do, you can’t drive like that in the rain. At the delivery of goods they give you a motor without a box, documents and even with a small scratch on the lid. When I asked where the equipment was, the manager replied that the supplier brought them in this form and offered a bag. D When I arrive home, the first thing I do is run to change the motor. I remove the rack, remove the motor, install a new one, connect it to the connectors, and simultaneously check its functionality. I had just started to screw the engine to the mounts when I decided to check whether the rack would fit the new engine, since it differs slightly in size from the factory one. I connect the rail and see that it does not fit the slots at all. There were ideas on how to make it fit, but reason prevailed over flights of fancy and I decided to change the gear motor in the store. 15 minutes later I’m already approaching the store’s checkout counter. As soon as the seller saw me, he asked: “Well, didn’t it fit?” I really wanted to tell him a lot about the low-quality spare parts, but I only said a modest: “Yes, can I replace it?” The store manager said that my case is not the first and that gear motors come from the factory with two types of splines - large and small. I came across just a small one, but they didn’t have a large one in stock, so I wrote a statement and my money was returned.
A box with a new gear motor =) You can immediately see that this is the original.
I drove home upset, but on the way I noticed a small store called “Samara”. I go there, there is a young girl at the checkout who happily helped me choose the right gear motor. Moreover, I got it in a branded box, with quality control marks, a guarantee and instructions for connecting, and even for 1,700 rubles. I was extremely happy when the motor fit without any problems. This is how, for relatively little money and in 3 hours of total time, I got rid of the problem with non-working wipers.
Comparison of two motors - on the right is the factory one, on the left is the new Samara one.
PS, I saw many topics on the forums with the problem of the wipers not returning to their original position. In fact, the solution is very simple - you need to adjust the splines connecting the rack and the gearmotor. You need to let the motor rotate its axis a full cycle and then insert the rack in the desired position and that’s it, the problem will be solved.

You are here: Home > VAZ > Kalina > Why wipers don’t work on Kalina
Possible causes of the malfunction and ways to eliminate them:
When the windshield wiper is on, the electric drive does not work:
Fuse blown:
- remove the cover located to the left of the driver, under the steering column, under it there is a mounting block;
- on the cover of the mounting block there is a diagram of the location of the relays and fuses of the car, we find the required fuse and change it if necessary;
Relay fault:
If the wipers on the Lada Kalina do not work intermittently, you need to change the relay located in the mounting block, next to the fuses.
Wiper motor malfunction:
- we check the ground terminal of the electric motor, screwed to the car body next to the rack;
- we clean it and the attachment point;
- install in place;
VAZ 1117 If this does not have a result, disconnect the connector for the electric drive of the windshield wiper, located under the windshield frame.
Using a tester or any other continuity test, we check whether power is coming to the connector. If power comes in, then it is necessary to change the wiper motor.
Disconnect the terminals from the battery. Remove the decorative caps from the leashes. Unscrew the nuts securing the leads and remove them. Remove the plastic grille under the windshield frame by unscrewing the bolts that secure it. Having unscrewed the trapezoid fastening (two bolts and one nut), remove the electric motor from the box and disconnect it from the trapezoid. We install a new one, repeating the procedure in reverse order.
If power does not come to the connector, the steering column switch must be replaced. Disconnect the battery terminals. Remove the plastic steering column cover. Disconnect the switch block and, pressing the latches on both sides, remove the steering column wiper switch. Install a new one by repeating the process in reverse order. Assembling the casing.
When turned on, the wipers on Kalina do not work, but the electric drive rotates
It is necessary to check the condition of the gearbox and wiper trapezoid.
Unscrew the plastic grill under the windshield frame. First remove the wiper arms and unscrew the nuts that secure them. We check whether the gearbox axis of the electric windshield wiper drive rotates.
If the axis rotates and the trapezoid is stationary, check the splined connection of the gearbox and trapezoid, and if necessary, tighten the fastening nut. If the connection is severely worn, it is necessary to replace this unit.
If your windshield wipers on your Lada Kalina do not work, this is not a reason to despair. As a rule, the cause is a minor malfunction. Such as a blown fuse or a loose nut on the spline connection between the gearbox and the windshield wiper drive, which can simply be tightened.
The windshield wiper electric drive system is quite reliable and does not require special maintenance. It is enough to follow basic operating rules. If during the winter period the wipers are frozen to the windshield, then before turning on the windshield wiper, it is necessary to free them from ice. And they will serve you without causing any problems.
Removing the windshield wiper mechanism completely is quite an easy job, for this we need 10 by 13 heads, a ratchet, a knob, a 10 and 13 ring spanner, you can also use an open-end wrench.
First of all, you need to get down to work on removing the wiper arms and plastic linings; detailed information on removing the plastic linings can be read here: Replacing the cabin filter on a Lada Kalina.
If you have sorted out the removal of the plastic covers, we proceed to the process of unscrewing the trapezoid mounting bolts. First, unscrew it on the left, as shown in the picture.
Then in the center.
After this, unscrew the nut on the right side; for this it is better to arm yourself with an open-end wrench.
Now there is nothing holding the trapeze, you need to slightly tilt it forward.
We take it out of the seat.
The final step when removing is to disconnect the power plug of the motor. To do this, you just need to bend the plug lock and remove the plug. First you need to disconnect it from the body; the plug is attached to a clip.
Removing and installing the windshield wiper motor on Lada Kalina
The motor is connected to the trapezoid by 3 bolts and one nut. So we unscrew the 3 bolts using a 10mm socket.
After this, unscrew the nut securing the trapezoid and the motor shaft.
You can remove the motor, since there are no more fasteners.
If there is a need, we replace the trapezoid or motor and assemble it in the reverse order.
How to remove the trapezoid assembly
Before proceeding with the removal, it is necessary to remove the wiper arms, as well as the plastic lining at the very bottom of the windshield, which I wrote about in the instructions for replacing the Kalina cabin filter. There you will need just TORX T20.
After these pads are removed from the car, you can begin to unscrew the bolts and nuts securing the trapezium itself. First, unscrew the bolt on the left, as shown in the photo below:
When is it necessary to replace windshield wipers in Kalina?
Over time, owners of practical Lada Kalinas notice the appearance of brush marks on the surface of the windshield. Such “artifacts” create an obstacle to good visibility. In this situation, the indicated components will need to be replaced, and the trapezoid will likely need to be replaced
Many experienced owners advise purchasing frameless brushes, which, in their opinion, are able to “bravely” withstand temperature changes and can demonstrate a relatively longer service life of approximately 1.5 million cycles
Before replacing, you should understand the required size of the products. For Lada Kalina, you should purchase a driver's side brush with a length of 600 mm, and for the glass area opposite the passenger - 400 mm. For stern glass, the brush has a standard parameter of 360 mm. This wiper needs to be replaced much less frequently, since the intensity of its work is significantly lower compared to the front components.
When do you need to change wipers on Kalina?
It often happens that the wiper drive system works, but marks remain on the windshield that interfere with normal visibility. In this case, the wipers need to be replaced. Previously, domestic cars were equipped with brushes, into the frame of which a rubber part was inserted, which cleaned the glass. But recently frameless brushes have been used.
They work better, and their resistance to different weather conditions is higher. Although frame brushes are cheaper, frameless brushes will last longer. They can operate efficiently from 1 to 1.5 million cycles.
When planning a replacement, you need to consider the size of the wiper blades. For the Lada Kalina, this is a 600 mm blade on the driver’s side of the windshield and a 400 mm blade on the front passenger side. On the rear window, the standard blade is 360 mm long. The rear wiper is replaced much less often than the front ones. They wear out much more slowly because they have to be turned on less often.
What to look for when choosing?
It is no secret that the level of visibility to the rear depends on the efficiency of the brush, which is especially important when maneuvering in cramped conditions and in bad weather. When choosing, you should lean toward high-quality branded products that will not subsequently emit an annoying squeak when rubbing against the glass and do not have to think about how to remove and replace the wiper. You should also inspect the integrity of the working element of the brush, which initially should not have cracks or breaks. An important role is played by the force with which the rear wiper is pressed to the surface of the glass, as well as the material from which the product is made.
What are the best windshield wiper blades?
Today there are 3 types of windshield wiper blades:
- frame;
- frameless;
- hybrid.
Frame
The most common type of windshield wiper blade. The principle of operation is that the wiper consists of several small rocker arms connected to each other by hinges. This system presses the rubber base against the glass.
Until recently, the hinge axes of this type of windshield wipers were completely metal, which led to their loosening and corrosion, and consequently to rapid failure. Modern frame wipers are free from this problem - the bushings and axles are made of plastic, which is why they are less susceptible to corrosion and icing. At above-zero temperatures outside, this design copes better with precipitation.
Advantages of a frame windshield wiper:
- Low price for a cleaning tape that can be replaced on the brush.
- Easy to replace rubber bands - even beginners can handle it. You need to remove the brush and remove the worn element; First trim the new tape in length and carefully insert the replacement element into the rocker arm mounts, and then secure it with thin steel plates.
- The steel frame is durable, and in some models it is protected by plastic covers that prevent moisture and dirt from entering the hinges.
- Wide distribution and availability of brushes of this type.
Flaws:
- ice or snow getting into the rocker area, which can cause the joint to become immobile;
- appearance can also turn into a disadvantage, especially when the paint layer begins to deteriorate and corrosion appears;
- high windage, which causes the brushes to lose effectiveness at high speeds.
Frameless
This model does not have a skeleton and a separate cleaning tape. It is a plastic strip with a clamping element inside it. The body is made of plastic with rubber and is usually made in the form of a spoiler.
This shape was not chosen by chance - it helps to better press the brush into the glass surface. Typically, there are plastic plugs at the ends of frameless wipers, which allow you to easily change the rubber blade.
Many drivers prefer frameless wiper blades due to the following list of their advantages:
- attractive appearance;
- Thanks to the uniform pressure, you can clean glass of any curvature;
- the frameless brush design provides high aerodynamic characteristics;
- less exposed to snow and ice due to the absence of hinged joints;
- Low profile provides maximum visibility on the road.
Flaws:
- high price compared to frame specimens;
- it is not possible to replace the rubber band;
- Frameless brushes sometimes have to be selected for a specific car.
Hybrid
This type of windshield wiper combines the advantages of the previous two versions. The design is a reduced system of frame rocker arms with hinges, covered with a compact plastic casing in the form of a spoiler.
These windshield wipers have the main advantage of frameless models - the effect of an aerodynamic wing, which contributes to a better fit of the rubber blade to the glass surface.
A significant disadvantage of hybrid wipers is their very high cost.
Do-it-yourself troubleshooting
When the drive works when the wipers are turned on, but the wipers do not move, repairing the trapezoid in such a situation will come down to replacing the bushings.
To do this, you need to remove the trapezoid, which is located under the plastic decorative trim under the windshield. Windshield wiper repairs are carried out in the following order:
- unscrew and remove the windshield wiper blades along with the leads;
- unscrew and remove the plastic cover, for which you will need a TORX T20, or “star”;
- unscrew the trapezoid, which is attached to the car body with a nut and two bolts;
- disconnect the windshield wiper drive from the battery;
- remove the trapeze together with the drive.
If you do not remove the trapezoid, then when installing the bushings you can bend the hinges, which will lead to improper operation of the wipers. Therefore, it is better to remove the entire trapezoid and replace it not with weight, but with emphasis.
The destroyed bushing is immediately visible. It can be simply removed using wire cutters. To insert a new one, it and the locking ring must be steamed in hot water, otherwise it will not be possible to put it all on the hinge. Before putting on the locking ring, the bushing should be treated with lubricant (for example, lithol). All disassembly and assembly work takes a maximum of 40 minutes.
But if the central bushing “flies”, then most likely the entire windshield wiper mechanism will have to be replaced. Replacing a windshield wiper trapezoid is an even simpler task than the process of removing and installing new bushings. All work is carried out according to the algorithm described above.
Naturally, a complete replacement of the windshield wiper trapezoid will cost more than repairing the windshield wiper. But it will be more reliable. New ones are almost guaranteed to last longer than refurbished ones. Although some Lada owners claim that a rebuilt and repaired Kalina wiper trapezoid can easily last two years. Well, you should always base it on whether you are willing to spend time or money.

Cleaning windows and wiper blades
Risk of injury!
The windshield wiper may start working on its own and cause injury to you.
Windshield wiper system
Standard windshield wipers are designed to remove dirt, dust, and excess sediment from its surface. This allows you to increase visibility of the road at any time, including bad weather conditions: heavy rain or snow. For greater efficiency, the device is combined with a windshield washer, which sprays a special washer fluid under high pressure onto the glass surface. Thus, the glass is cleaned from adhering dirt and insects.
Some cars have a rear windshield wiper, as well as special devices for cleaning the headlights (washers). This allows you to ensure traffic safety in all weather conditions. The frequency and duration of operation of the windshield wipers is regulated by the driver from the passenger compartment.
Original sizes of brushes on Grant
The length of the driver's windshield wiper is 600 mm. The length of the passenger wiper is 410 mm. Fastening type - “hook” (in English hook).
Foreign manufacturers indicate the length of the windshield wiper in inches, so the suitable length for a passenger blade is 16″. Sixteen inches - 406 mm, probably because of this, brushes with lengths of both 40 and 41 cm can be installed on the right side of the Granta. If desired, you can install a passenger windshield wiper up to 45 cm, but I would recommend staying in the range of 400...410 mm.
I have added brush article numbers to the selection: they will help you find specific products in stores that sell auto parts (this is faster and, most likely, cheaper). Also, the articles will allow you to avoid compromises in the form of several centimeters in the length of the brushes - choose only what is made specifically for your car.
Finally, a comparison of prices for windshield wipers.
Why wipers don't work on Kalina
The Kalina car is available in three body types. If "Kalina" has a sedan body. then the wipers are only on the windshield. and on hatchbacks and station wagons. The second wiper is located on the rear windshield.
There is a wiper mode switch on the steering column, which also works with the windshield washer. To the left of the steering column, there is a mounting block, there is a 20 amp fuse F4. protecting the electrical circuit of the wipers from overloads and a relay that allows operation in intermittent mode. The electric motor with gearbox and brush movement mechanism are located in front of the windshield.
If, when you turn on the windshield wiper, you do not hear the noise of the engine running, you will first have to check fuse F4. You can get it out using gray tweezers located in the cell on the far right of the mounting block. Having taken out the fuse, we look through the window where the thread should be. If it is empty, then it is burned out, but there are times when the thread burns out in the body itself, and then it will seem to you that it is intact. If there are such suspicions, it can be checked with a test lamp. Before replacing a fuse, it is necessary to find the cause of its failure. You also need to check the fastening of the ground terminal; it is located on the car body near its left pillar.
If the electric motor still does not work, you will have to check whether voltage is supplied to it. This can be done using a warning lamp with the ignition on and the wiper mode switch. There are two options here. First, there is power, which means you need to look for the cause in the electric motor itself. Its brushes may freeze or the armature winding may burn out. Second option, there is no power. Then you will have to disassemble the steering switch and check the condition of the pads for oxidation of the contacts.
If the windshield wipers do not work intermittently. you need to check the K6 relay located in the mounting block. The easiest way to do this is to replace it with a known good one. When the wiper motor is running, but the brushes are not moving, the cause may be loose fastenings of the nuts of the drive mechanism or shearing of the gear teeth in the gearbox.
If your brush speed has decreased, you will have to disassemble the gearbox. since rust appeared on its axle due to lack of lubrication.
The device of a windshield wiper is not so complicated and almost any driver who understands technology can fix malfunctions that may arise during its operation.
Possible causes of problems
Some experts argue that if the windshield wiper blades do not work when turned on, then the most common reason for this is a failed fuse. In this case, no special efforts will be required to fix the problem. You just need to open the fuse box cover (on the left under the steering column) and find the appropriate fuse. A diagram printed on the inside of the lid will help you do this.
If the wipers do not work intermittently, then the relay may have failed. It is located in the same place as the fuses. It needs to be replaced with a new one. But, as statistics provided by owners of Lada cars show, fuses or relays blow out quite rarely.
A very common reason why the Lada Kalina windshield wiper blades do not work is the destruction of the bushings. As experienced drivers say, plastic bushings fall apart very quickly - their service life is at most 3 years.
Perhaps the reason for their destruction is the quality of the plastic. But, alas, there are no other bushings. The repair kit can be found in specialized auto stores.
When the wiper drive does not work, the reason may be a failure of the motor that drives them. To find out whether the electric brush drive has really burned out, you need to check whether electricity is supplied to it. This can be done using a tester. If power is supplied, then the overheated motor needs to be replaced.
Modernization of wiper arms for Lada Kalina 2
It is not always possible to buy a wiper arm for the first Kalina; in this case, the design can be modified. It is necessary to remove the leash and tension spring. Then drill a new hole in the metal bar of the lever closer to the brush. We install the spring using a screwdriver, clinging it to the new hole. Now the tension will be stronger, which will allow the rear wiper to clean the glass better.

By the way, another way to solve the problem of poor cleaning of the rear window is to install a frameless wiper. Let us remind you that the front wiper blades can be installed in larger sizes.
For Lada Granta, Kalina, Priora
The resistor shown in the photo is responsible for the number of strokes. Our task is to replace (using a soldering iron) it with a resistor with lower resistance. To get two sweeps of the wipers after washing the windshield, it is enough to solder a resistor with a resistance of 47 to 68 kOhm (0.25 W). To make three swings - from 70 kOhm. The result of the modernization on video:
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.
