Good day!
at the slightest grip of the wiper with ice and an attempt to turn them on, the splined connection immediately turns (well, at least I don’t have other versions yet). after tightening it a third/half turn they start working normally. This has never happened before, I suspect that part of the spline connection or the mating part on the wiper arm could have been eaten. What in this case needs to be changed with minimal losses? I’ve never encountered such a replacement, so I’m afraid to buy extra hardware.

And by the way, there are no slots on the leashes!

Try placing a washer under the nut for better pressing.

From a car forum from my city, from one good person:

To get there, turn the passenger wiper in your direction, and then

And by the way, there are no slots on the leashes!

The thread is intact and stretches.

How's the traffic on your Moscow Ring Road? How did you get out of the car?

this fall I stood on the side of the road in a downpour - the front was constantly burning at 20a (2 wipers at maximum speed - and it didn’t come) so I later found out while I was getting to the trapezoid - I was looking for something - maybe something was sticking... in the downpour, on the far right people for 100 kU it’s too fast, overtakes on the roadside, a couple of times I thought they’d definitely fly in (the hazard lights and rear fog lights were on) in general I suffered a lot in half an hour... I couldn’t concentrate on the problem, I was driving towards the fire

Why don't the emergency lights and turn signals work on the VAZ-2112?

Car : VAZ-2112. Asks : Sokolov Vladislav. The essence of the question : the emergency lights and turn signals on the VAZ-2112 do not work, what should I do?

Hello! I came across this problem. I left the garage, everything was fine, the police stopped me at the intersection and fined me for non-working turn signals . I'm at a loss, why, the weather is good, nothing should get stuck? I started to figure it out, checked the relays and fuses, they turned out to be normal.

Tell me, who had this problem, where to look? As I understand it, there is no contact, maybe the problem is in the block? Two weeks ago I changed the steering wheel . The unit was dismantled, the contacts are not scorched, there is no burning smell. What do you recommend, go to a service center or would it be easier and cheaper to buy a new unit, but what if it’s not the cause?

DIY windshield wiper restoration

It may happen that your windshield wiper blades require replacement much more often than you expected. Weren't they replaced last year? But they again leave streaks, no longer clean the windshield efficiently and make annoying sounds. Although windshield wipers are not the most expensive element in car maintenance, the cost adds up each time they require replacement, which can add up to a significant cost.

↑ Adjusting the gearshift lever VAZ-2110

Now you need to adjust the position of the lever. To do this, we involve an assistant who sits in the driver’s seat and moves the gearshift knob to the optimal position for adjustment. Typically the lever is centered and moved slightly to the right. In this position of the lever, we tighten the clamp while the assistant holds the lever in this position.

Now all that remains is to check the correct operation of the gear shift lever, and if something is not satisfactory, you need to make the adjustment again.

What to do if the wipers stop in the middle of the glass

Car wipers are an integral attribute of any car, which, as a rule, is remembered only in the event of any precipitation (rain, snow). In poor visibility conditions, wipers clear the car's windshield, providing the driver with the necessary visibility.

Advice! and instructions on how to replace wipers on a car.

In general, the design of automobile windshield wipers ensures that the wipers operate in three modes:

The three-speed windshield wiper system is one of the weakest points of any car. This is especially true for domestic cars, in which quite often the wipers do not return to their original position during operation, but stop in the middle of the glass.

Stopping the wipers in the middle of the windshield can infuriate even the calmest driver, as this limits the view. In addition, the wipers, stopping in the middle of the glass during operation, constantly remind you of the presence of a malfunction.

There are a lot of reasons that lead to wipers stopping in the middle of the glass, and most of them can be eliminated independently.

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.

Reasons why wipers stop

Among the reasons that cause wipers to stop in the middle of a vehicle's windshield, the most common are:

Malfunction of the motor-gearbox contact group.
Irregularities in the operation of the limit switch.
Wear or chipping of the teeth of the wiper drive splines.
Incorrect assembly of windshield wiper elements after repair.
Malfunction of the electric motor or its switch.

Checking the serviceability of the turn relay.

First, make sure that the measuring instruments and control lamps on the instrument panel are working.
If they do not work, then check the fuse. If the devices are working properly, turn on the hazard warning button and check that all the lamps in the direction indicators are blinking. This will allow you to divide the circuit into two parts and speed up troubleshooting. If the alarm does not work when turned on, then it is necessary to check the serviceability of the turn and alarm relay and the presence of power at its terminal 49. The pin designation is marked on the bottom of the relay, next to the contact legs.

We remove the relay, which is marked in the form of a triangle on the top of the case, from the mounting block, and in the vacated socket, using a test paw, check for the presence of a plus on pin 49. We connect the test lamp to the ground or minus of the battery, and with the other end we touch pin 49, when If the hazard warning button is on, you do not need to turn on the ignition. Lack of power indicates a faulty fuse, alarm button or broken wires, contact tracks of the mounting block and poor contact in the connectors.

If the lamps do not light up, but there is a plus on pin 49, then there may be a short circuit in the signal lamp circuit and the fuse has blown. A short circuit can also cause the relay to fail. In this case, check the serviceability of the fuse, and if it blows, eliminate the short circuit in the signal lamp circuit.

Troubleshooting if turns do not work, even if you do not have special knowledge.

Checking the serviceability of the turn relay.

And so let’s look at what to do if the turns of a front-wheel drive VAZ, except for the 2170 Priora, do not work. The operation and troubleshooting of which was discussed in the article “Prior Turning Relay”.

First, make sure that the measuring instruments and control lamps on the instrument panel are working. If they do not work, then check the fuse.

If the devices are working properly, turn on the hazard warning button and check that all the lamps in the direction indicators are blinking. This will allow you to divide the circuit into two parts and speed up troubleshooting.

If the alarm does not work when turned on, then it is necessary to check the serviceability of the turn and alarm relay and the presence of power at its terminal 49. The pin designation is marked on the bottom of the relay, next to the contact legs.

If there is a plus on the terminal, then connect terminals 49 and 49A with a copper wire. If the connecting wires and connectors are in good condition, all the direction indicator lamps should light up. This indicates that the turn signal and light signaling relay is faulty. If the lamps do not light up, but there is a plus on pin 49, then there may be a short circuit in the signal lamp circuit and the fuse has blown. A short circuit can also cause the relay to fail. In this case, check the serviceability of the fuse, and if it blows, eliminate the short circuit in the signal lamp circuit.

Checking the hazard warning button.

If the hazard warning lights are working, then the turn signal and hazard warning relays are working properly, but the fault may be in the hazard warning light button. First, check the plus, as described earlier at pin 49 of the relay, with the hazard warning button off and the ignition on.

If there is no plus, then you need to check the serviceability of the alarm button. To do this, you need to remove the button from the socket by prying it off with a thin screwdriver or remove the instrument panel visor. In the contact connector of the button, use a test lamp to check the presence of power at pin 2 (the numbering of pins on the button near the contacts) with the ignition on. If there is no power, repair the broken wire from the instrument panel to the button. If there is power, connect pin 2 to pin 5 in the button socket, with the ignition on, and turn on the direction indicators of either side. If the warning lights on this board light up, replace the faulty hazard warning button.

If the warning lights do not light up, then, without removing the jumper from the hazard warning button block, connect pins 49 and 49A with a copper wire in the relay socket, then check the power at pin 49A of the turn switch. To do this, remove the steering column cover and the connecting connector from the turn switch. You can also remove the switch itself to determine the pin numbers that are marked on its lower part next to the contact legs. This is not difficult to do by squeezing the latches on the sides of the switch and pulling it to the side. If the circuit from the relay to the switch is in good condition, the indicator lamp will start to light. If the control lamp does not light, then repair the break in the wire from the mounting block to the turn signal connector.

When turning on the turns, the fuse blows.

Another malfunction of the direction indicators is the fuse blowing when the indicators of one of the sides are turned on. To quickly identify a malfunction, turn on the hazard warning lights. The signal lamp in a circuit that has a short circuit will not light up or will burn at full intensity. A sign of a short circuit in the signal lamp circuit can be a buzzing sound from the turn signal relay when the indicators are turned on. To facilitate troubleshooting when the VAZ direction indicators do not work, use the diagrams below.

Relay or fuse?

The diagram shows the fuse box. The arrows indicate the relays and fuses for the hazard warning lights and turn signals. The VAZ-2110 may have a different mounting block.

First, check fuse F16. After relay K3.

Symptoms of a faulty relay

When idling, the turn signal signal on the instrument panel fades. If so, then the relay is already faulty.
