Windshield wipers work slowly, trapeze repair
In a previous article I wrote about replacing the trapezoid and motor, and did this along with one necessary repair.
Last night, when I turned on the wipers on my Kalina, I noticed that they practically did not move. In short, they were barely crawling on the glass, although a couple of days ago everything was fine! At first I thought that the problem was in the wiper blades, but when I bent the arms a little, I realized that the blades had nothing to do with it. It was decided to remove this entire structure from the car and see what was the matter. So, the first thing you need to do is remove the Kalina wiper trapeze. Then, having disconnected it from the motor, try how easily its levers move by hand. In my case, one side (the driver's wiper) moved normally, but the other side moved with such force that I was even surprised how the motor was even able to move this lever. In order to solve the problem with the slow operation of the wipers, it is necessary to remove the shaft with the splines that is difficult to move. In general, to do all this, you will need:
- Pliers
- Penetrating lubricant
- Litol lubricant or similar
- Hammer
- Thin screwdriver
So, the first thing you need to do is use pliers or your hands, if possible, to remove the rubber band from the shaft, as shown clearly below:
Then use a thin screwdriver to pry up and remove the retaining ring, as shown in the photo:
And we take out all the washers that are mounted on the shaft, there are several of them:
To begin with, now you can simply try spraying penetrating lubricant on the shaft, perhaps it will penetrate inside the hole and help ease the movement:
If this does not help, as was the case in my case, then it is necessary to knock the shaft out of the seat of the trapezoid body. To do this, screw a nut onto the shaft thread and gently hit it with a hammer, thereby knocking it out:
As a result, we get the following picture:
As you can see, a strange coating has formed on it, which must be removed with fine sandpaper, as I did:
And lubricate the shaft with thick lubricant, I personally used lithol:
And after this has been done, you can insert the shaft back into the trapezoid body and try how easily it can move there. Personally, in my case, everything immediately went like clockwork. After installation, the wipers began to work perfectly, even better than in the last few months.

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
in intermittent mode, it is necessary 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 needs to 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 spline connection of the gearbox and trapezoid, if necessary, tighten the fastening nut. If the connection is severely worn, it is necessary to replace this unit.
If your windshield wipers do not work on your Lada Kalina
, 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.
How to troubleshoot purifier malfunctions yourself?
When the owner of LADA Kalina turns on the windshield wiper drive, the motor works, but the wipers refuse to move, then the bushings will have to be replaced. For this purpose, the trapezoid of the wipers is dismantled, which is covered by a decorative plastic panel. The location of the unit (trapezium) is directly under the windshield. Repair of the windshield wiper is carried out using the windshield wiper trapezoid repair kit in the following order:
- unscrew the fasteners of the brushes and remove them together with the leads;
- then we dismantle the decorative protection panel, for which we stock up on a Torx T20 wrench;
- we move on to removing the trapezoid itself, which is held on the frontal body element by means of a nut and a pair of bolts, using, if necessary, a repair kit for the windshield wiper trapezoid;
- Next, you will need to disconnect the supply lines of the unit from the battery;
- Now you can remove the assembly.
Replacing wipers on Kalina Avto-Gid
Lada Kalina Hatchback UltraViolet Logbook -062- How to drain antifreeze
Car wipers (we are talking about the windshield wipers themselves, not the blades) are usually durable parts. They are almost not affected by aggressive factors - except moisture. For this reason, they can easily serve without replacement for the entire time that the car is in use. However, occasionally they still have to be dismantled. In particular, this must be done if, for example, you plan to replace the windshield. The procedure for removing wipers is not at all complicated, but car services will charge you money for it, which may be useful for other purposes. In this article we will tell you how to remove windshield wipers in the correct way using the example of a 1st generation Lada Kalina car.
Tools and materials:
To remove the windshield wiper you will need:
- Head or key 13, new front wiper arms, if you change them (articles: 11180-5205065-00 on the driver’s side and 11180-5205066-00 on the passenger’s side) - for front wipers;
- A wrench for 10, a new rear wiper arm, if you change it (article: 11170-6313150-00 or 11190-6313150-00 depending on the body type - station wagon or hatchback) - for the rear wiper.
Replacing front wipers on Kalina
Before you start dismantling the wipers, remember that it is better to do this on the driver’s side with the head, and on the passenger side with the key, otherwise there is a risk of scratching the hood. However, if you are careful, the hood will not be damaged regardless of the tool used.
1) First of all, remove the plugs from the plastic. You will see nuts under them.
2) Take the head (wrench) and unscrew the nut. There will be a washer under it, pull it out immediately, otherwise it may get lost during the process of removing the wiper.
3) Then remove the windshield wiper. That's all.
4) It should be noted that before removal it is worth remembering, or even better, photographing exactly how the wipers were located on the glass. When you put them back, this information will be useful to you. If you put them in the wrong position, they can hit the pad below during operation, scratching it and damaging the brushes.
5) Install the windshield wipers in the reverse order.
Replacing rear wipers on Kalina
This procedure is only relevant for owners of a Lada Kalina hatchback or station wagon, since sedans were not equipped with a rear wiper. Remembering the location of the wiper will be useful here too, so take the time to take a photo of it before removing it.
1) First, lift up the metal cap that covers the nut.
2) Take a 10mm wrench and unscrew the nut. Just like on the front, there will be a washer under the nut, don't forget to remove it. Rock the wiper back and forth and pull it towards you, it will come off quite easily.
3) Reinstallation is carried out as usual, in the reverse order of removal.
Let's sum it up
Such an important process as replacing wipers, or when changing the windshield wiper trapezoid on a LADA Kalina car, is a very simple undertaking. There is no need for special devices or fancy tools. The brushes are removed by opening the locks.
Repairing or replacing a part such as a windshield wiper trapezium appears as a more responsible job, but it is not capable of causing difficulties for an inexperienced owner of a Lada Kalina. In such situations, do not hesitate to take action.
I did it myself. The windshield wipers don't work. I did it myself.

Hello!
With the purchase of Kalina, the problem of non-working wipers arose. More precisely, a floating problem, sometimes they work, sometimes they don’t. I started to blame the mass that was not tightened, I found current in 2 places, I cleaned them and tightened them: It turned out that the masses were not tightened, the pin and the area around it were well painted.
Tightening the available masses certainly did not help. Well, okay, let's act. I decided to remove the trapezoid, lubricate it and lay a separate wire to the gearmotor.
To remove the trapezoid you must:
- Unscrew the wiper arms. To do this, remove the caps by simply prying them off with a screwdriver. We unscrew the nut with a size 13 wrench and remove the leash by shaking it. It is highly advisable to mark the position, for example, with a thin marker or nail:
- Then, using the star wrench, unscrew the 4 screws and remove the decorative trim under the windshield:
- Remove the trapeze. It is secured with 2 nuts and one bolt, here we need a 10mm wrench:
- Next, it is advisable to mark the position of the motor axis relative to the trapezoid. Otherwise it will be excruciatingly painful. Remove the black protective caps and lock washer from the trapezoid, and pull out the axle. I smeared it with lithol.
Reassemble in reverse order. During assembly, I screwed on the additional mass and threw it onto the body. The wipers run and make you happy. I also changed the windshield washer nozzles. They didn’t fit quite tightly, so I made gaskets from tin to make them stand tightly. Now the wipers are fast and 4 streams wash the glass.
Good luck!
The wipers did not adhere well to the windshield. Solved the problem for 30 rubles!
With the onset of winter, I encountered an unpleasant phenomenon - windshield wipers began to leave streaks in several places. The problems were especially pronounced on the driver's side. I decided to figure out the causes of the problem myself, and was able to quickly fix it myself. I will share a simple method later in the article.
When wipers begin to leave streaks on the glass, many car owners change their wiper blades. But I immediately abandoned this idea. The brushes were replaced three months ago with high-quality ones, so they could not wear out during this period. It became clear that the problem lay in the windshield wiper arms. The situation with their replacement looks unattractive.
I found a set of original leashes for my car, but the price surprised me. It would cost me 11,000 rubles. Chinese analogues cost about half as much, but their quality is clearly lower, and the amount still remains considerable. It was decided to try to restore the old leashes. It turned out that doing this is not as difficult as it might seem.
The leashes are pressed against the windshield due to a spring installed inside them. Over time, it stretches and the force on the surface becomes less. The wear of the spring is affected by its long stay in the “service” mode. Many drivers raise their windshield wipers in winter to prevent them from becoming covered in ice. The solution is useful, but you should be prepared for problems with pressing the wipers to the glass.
First I removed the leashes, this procedure can be difficult. The leads stick to the slots, so it is problematic to pull them out of place. I placed a rag between the blades and the windshield. With one hand he pulled the leash towards himself, and with the other he lightly tapped them approximately in the middle. This method made it possible to dismantle both elements without much effort.
On the back of the leash there is a spring that needs to be removed. I did this using a vice and steel wire. The leash was clamped in a vice, and the spring mount was pulled towards itself with a wire
It holds tightly, so it is important to follow safety precautions. At a minimum, you should wear safety glasses.
In theory, you can restore the spring, for example, trim a few turns. But I decided to go to a large domestic auto parts store. The seller selected a new one based on the old spring. It was originally intended for the braking system, but was perfect for leashes. I installed the new spring in a similar way, using wire. Now the wipers remove dirt perfectly and do not “jump” on the glass.
Why wipers work slowly on Lada Priora and how to speed them up
March 30, 2016 LadaOnline 37 906 3
Many Priora owners notice that over time the wipers begin to work slowly. The speed has decreased several times and does not rise even when cleaning the wet windshield. Let's look at the main reasons for slow wipers, as well as ways to solve this problem.
The main reason for slow Priora wipers is the lack of lubrication:
- in the windshield wiper motor;
- on the hinges of the windshield wiper trapezoid.
Try to use a lubricant that does not thicken at low temperatures. The trapezoid with the motor can be removed, like on a VAZ 2110.
If lubrication of the motor and trapezoid does not help, we recommend using the modification. The Priora windshield wiper circuit consists of a large number of connections and contacts, each of which creates additional resistance. As a result, the power of the motor decreases, and the Priora's wipers work slowly. This problem can be eliminated with the help of modifications that will minimize current losses.
Required:
- 5-pin connector, like on the windshield wiper motor;
- 5-pin relay with socket - 3 pieces;
- wires 25 mm2;
- round terminals.
We assemble and connect the structure according to the diagram. That is, the resulting block of three relays is installed in the gap in the windshield wiper motor connector without interfering with the standard wiring
We recommend that you pay special attention to the insulation of the wires, and it is better to close the assembled structure in a box to prevent the ingress of moisture and dirt
circuit of three relays for accelerating windshield wipers Lada Priora windshield wiper motor connector Lada Priora installed circuit of three relays for accelerating windshield wipers Lada Priora
As a result, the windshield wiper blades will work faster than before. You can compare the speed of the wipers using the video clip (1 - before modification, 2 - after modification):
Have you encountered a problem when the windshield wipers started working slowly on a Priora? How did you manage to increase their speed? Let us remind you that on the website you can also find instructions in case the windshield wiper blades do not work at all. Did you know that you can increase the cleaning area of your windshield by installing larger blades.

The relay is activated, but the engine does not start
By opening such a sign, it can be assumed that any of the above fuses or the electric motor itself has failed. We check fuses using a multimeter. If everything is in order, open the hood and inspect the trapezoid for deformation or an object in the structure. In winter, you can freeze the wiper blades against the windshield. This phenomenon is accompanied by similar symptoms, so if the VAZ-2109 windshield wipers do not work in frosty weather, first check their condition.
If the trapezoid is in working order and the windshield wiper blades can move, you will have to remove the engine for diagnostics. To completely eliminate other problems, after removing the engine, connect it directly to the battery terminals. Earned it. look for the cause in the electrical circuit, no. contact an auto electronics specialist.
Repair of windshield wiper motor gearbox Lada Granta
To disassemble the gearmotor, unscrew the screws securing the gearbox cover 6 and remove it together with the limit switch panel 4.
Then unscrew the screws securing the gearbox housing 11 to the electric motor housing 8 and disconnect them.
Remove armature 9 of the electric motor.
To remove gear 3 of the gearbox, unscrew the crank nut, remove the retaining ring from the axle and remove the axle with gear and washers from the housing.
After disassembly, blow out the internal cavities of the electric motor with compressed air to remove carbon dust deposits and check the condition of the brushes and commutator.
The brushes must move freely in the brush holders without jamming, and the springs must be intact and have sufficient elasticity.
Clean the commutator with fine-grained sandpaper and then wipe with a clean rag lightly greased with petroleum jelly.
If the collector is severely burnt or worn out, it is better to replace the gearmotor with a new one. Check for signs of jamming on the armature shaft journals.
If necessary, sand them with fine-grained sandpaper.
When assembling, move the brushes away from the commutator so as not to break them or damage their edges, and insert the armature into the body with extreme caution, avoiding hitting the armature on the poles so as not to break them. After assembly, to align the bearings, tap the gear motor housing with a wooden hammer, and then check it on the stand
After assembly, to align the bearings, tap the gear motor housing with a wooden hammer, and then check it on a stand.
When installing the crank, position it so that in its final position it is parallel to the short wiper rod and pointed towards the electric motor.
Data for checking the gearmotor
Rotation speed of the gearmotor shaft at a supply voltage of 14 V, a load torque of 1.47 Nm (0.15 kgf m) and an ambient temperature of 25±10 °C, min -1:
— first (small) 30–40
— second (large) 55–70
Current consumption at the above load torque, A, no more than:
— at first speed 3.5
— at second speed 5
If the brush springs are damaged or have lost their elasticity, replace them.
Check the ease of movement of the brushes in the brush holder.
They should move freely without jamming.
Replace worn or chipped brushes.
When replacing, solder the leads of the new brushes to the brush holder.
Clean the collector with fine sandpaper if it is dirty or has marks, scratches, etc.
If the commutator is badly worn or burnt, replace the armature or gearbox with electric motor assembly.
If you find traces of jamming on the armature journals, clean the journals with fine sandpaper.
Replace a gear that has severely worn or broken teeth.
Clean burnt or oxidized contacts of the self-stop mechanism with fine sandpaper.
Brush jumping on glass
Typically, the windshield wiper blade begins to jump across the glass, leaving radial streaks, in two cases. At high speed, the windage of the brush increases
and it is pressed away from the windshield - this effect is typical for frame windshield wipers without a spoiler. If you find yourself in such a situation, it is recommended to change the brushes to those with a spoiler or frameless ones with good aerodynamics. The second reason is a loose mechanism
rocker arms of classic brushes, mounting unit or arms of the windshield wiper system.
In such a situation, it is necessary to check the play of the drivers and rocker arms, and the correct attachment of the brush to the driver. If necessary, replace the brushes. The third reason is a bent wiper arm
. In this case, usually the brush cleans satisfactorily in one direction, but poorly in the other. In this case, there is a possibility that the leash is slightly twisted with a “screw”. In this case, you need to fix or replace the windshield wiper arm so that the cleaning edge of the wiper is at a right angle to the glass surface.

Here's what people write: the machine is a month and a half old, the wipers started dying over the last two weeks, in other words, they started working very slowly, they didn't reach the end, they froze in arbitrary positions, then they started to slow down completely. Yesterday we stood in the middle of the glass. I admit, at first I thought it was a lot. There was no time to go under warranty - I went to my favorite service I knew. and this is what happened. 1. The windshield wiper motor on a viburnum can actually be removed in a minute. you will need a 10mm, 13mm wrench, and preferably a 10mm socket to make it easier to turn. 2. The motor itself is located in the direction of travel on the left in the area of the left windshield wiper. 3. Unscrew one nut that secures the motor to the trapezoid with a 13 wrench, then with a 10 wrench, the three bolts that hold the motor itself. 4. take out the motor, remove it from the connector. 5. remove the pseudo-insulation from leatherette)) look at the block, it is really not protected by anything and the mass actually comes with a copper wire to the silumin antennae :wacko: 6. I had everything in order with the contacts, so we disassembled the motor itself, with a screwdriver this is done at a time. 7. There was just a ton of rust on the main shaft of the motor - and this was on a machine that simply hadn’t turned over for a month, they treated everything and filled it with lubricant. 8. as an additional Measures treated the same contacts on the block and antennae with an antioxidant - oxygen will not pass through. As a result, the wipers do not drive across the glass, but fly, I’m just as happy as a boa constrictor. all for 400 rubles)) if I had gone under warranty, I would have paid 180 for a car wash, 100 for diagnostics, I would have lost a lot of time and gasoline to go there)) and here: After a short stop due to the holidays during a trip along a country road, I decided to use the wipers. nope, they sluggishly crawled out into the middle of the glass and stood up. So I had to drive, periodically stopping and helping them with my hand. :shok: an autopsy showed that the drive axis of the left leash had soured in the trapezoid. Yes, the trapezoid is made more durable than the eighth one, instead of plastic seals in the viburnum, bronze ones are used, well, they forgot to put in lubricant and think about sealing it so that no water gets in there. As a result, they spent a very long time watering the axle with WD and “pulling off” the soured seals. Z.Y. I began to notice a long time ago that the wipers had lost their former agility, but they worked properly until the car was parked for several days. Z.Z.Y. If you also have the feeling that they have become less efficient, then try to sort out the trapezoid. (You don’t need to climb into the gearbox, only the drive axles.) To do this, you only need a couple of latches and a pair of wrenches. a bottle of “lithium” grease and of course HANDS!
