Motor wiper - when the repair is inevitable? Intermittent wiper mode does not turn on.

When driving a car in adverse weather conditions, the timely cleaning of windshield is of great importance, and the question often arises as to check the motor motor. The main purpose of the unit is to delivere the wind opening of the car from moisture, snow and other atmospheric precipitation, so we will understand how to maintain this mechanism in working condition.

Motor wiper - what is it and how does it work?

Modern cars are equipped with two windshield cleaners who for front glass Have a double design (there are two rubber bands on the brush for more efficient operation), and for the rear - the same option. Most of the wipers of the lobovik work in the three main modes. These modes are intermittent, slow and fast work.

Wiper lobovik includes in its design electrical engine With gear, leverage, brushes and mechanism, automatically returning to its original position. Simultaneously with the cleaner work is carried out. When this small but important mechanism It ceases to work, do not hesitate with its repair, because the weather is rarely predictable.

Repair of a wiper motorist - how to establish the cause of the breakdown?

There may be several reasons why the wiper does not work, consider common situations just below. First of all, there may be no contact between the collector and brushes. If, after disassembling the electric motor and stripping contacts, the malfunction was not eliminated, then in this case, the engine cleaner motor is most likely needed, but there are some more options that should be checked until cardinal measures.

In the event that the levers or the gearbox arrived, it can work a bimetallic fuse. Then your system will not respond either to try it on. Naturally, by adjusting the position of these components and replacing the fuse, you can solve this problem. After troubleshooting the wiper must work normally.

Sometimes this mechanism begins to function only at one speed. In this case, most likely, the switch or resistor is defective. Brushes may not be installed at the lower position, for this it is necessary to adjust the stop mechanism. Often there are situations when when the wiper is turned on, extraneous sounds occur as a viper or a grincling. If this is not related to the dryness of glass or the presence of sand brushes under the rubber bands, then, apparently, the jams of something inside, so it's time to look deep.

The storage of the wiper is not complicated. Brushes levers are attached to fingers, which can be the most first suspect sources outsided sounds. As a rule, they hide in the bushings of the bracket due to protection disorders, when water and dirt fall inside. If the device has passed this testing successfully, and the sound is preserved, it is necessary to repair or replacing the engine motorcycle cleaner.

In order to remove the motor, you need to de-energize the electrical system, and only after that it can be dismantled.

Replacing the engine motor cleaner - how to remove the device?

Sometimes the rear wiper motor, as well as the front, simply fails. It is unlikely that it will be frequent breakdownBut if she caught you, nothing can happen, you have to understand. In order to repair the device, it needs to be removed, and this is a rather laborious process. For example, it is usually given classic VAZwrist models that are most fully demonstrating the entire technical process. So, the removal of the motor takes place in several stages:

• The nuts are unscrewed, which are attached to the brushes levers, after which they can be removed from the conical slots of the drive. If it is difficult to do it, penetrating lubricant can be applied to the slot.
• Drives of brushes levers are dismantled by unscrewing fastening nuts, and then removal of plastic bushings and rubber gaskets.
• The wire block in the harness is disconnected and removed by lifting the edge of the seal, through the slot in the partition of the engine compartment.
• The next step is made directly removing the wiper. Then the washer and spring retainer is unscrewed from it, the thrust is disconnected.
• After unscrewing three fastening bolts, you can get a motor.

After visual inspection, all unsuitable parts should be replaced. If recovery is not possible, you should purchase a new motor. Assembling the entire system of cleaning the glasses is performed in the reverse order.

The gear motor is an ordinary electric motor that can work in different modes. In the case of a wiper, it has 3 modes of operation: intermittent, 1st speed, 2nd speed. Also, the motor gearbox has a built-in bimetallic fuse, which is either on its body or inside.

Remove the gear motor to replace it, maintenance: brushes, fuse; To remove the trapezium.

Signs of a dead gear motor:

When possible reasons, do not rush to change the gear motor! To begin with, get acquainted with the rest possible reasons Faults by clicking on the link.

How to remove the motor reducer of wipers?

To remove the gear motor, we need to unscrew only 4 mounts! But there are two nuances:

• not convenient location;
• it is necessary to remember the position of the crank.

Krivoship is a curve from the Motor to the trapezoid traction. If you do not correctly install the crank, then the likelihood of damaging the teeth on the new engine is great.

So:

• Open the hood, turn off the wire block from the fuse block to the gear motor.
• We remember (we indicate the marker) the position of the crank.
• We unscrew the kiroshype mount to the Motor key to "13", remove it.
• The key to "10" we unscrew the three bolts of the mounting gear of the gearbox to the trapezoid.
• We take out the gear motor.

If the gear motor is not pulled out, unscrew the fastening of the fuse block and move it.

How to install a gear motor?

Before installing the gear motor, you need to make sure that the motor shaft is in initial position. To do this, without installing, we connect the block of wires to a new motor and temporally turn on the intermittent mode of the janitor's operation. After stopping the motor, the shaft will be in the initial position.

After that, we disconnect the block and install the motor, taking into account the position of the crank marker.

Any breakdown in the car - the "end of the world" for the driver. And if we are talking about such a gentle device, like a VAZ, the situation is even worse. About how to cope with the malfunction of this device - below in the article.

Principle of operation, function and location of the motor

This device is universal for many vehicle- not only for a car that will be discussed. The principle of operation of the wiper is quite simple: through the small intervals of the Time Motor Girl gives a signal and brushes look with windshield dirt, rain and so on. The work of the wiper can be different: constant, single, as well as at a given time interval. An additional device in the paper is the device for starting water.

Making a conclusion, it can be concluded that the mechanism consists of such details:

• lever ax;
• the lever of the brushes, the brushes themselves and the knitting needles on which the brushes are kept, in a different "brush holder";
• relay;
• mounting block;

Together, the listed elements constitute a single coordinated mechanism working for the benefit of the driver and passengers.

Major faults of janitors and ways to eliminate them

Breakdowns arise for several reasons:

• if the contact is broken between brushes and manifold, wipers will refuse to work;
• if the fuse has worked due to the failure of the levers or gearbox;
• if the switch or resistor is faulty;
• brushes can creak and publish other irritating sounds.

To solve the first problem, you need to disassemble the mechanism engine and clean the contacts. If the work has not recovered, then most likely the fact is that the motor of janitors broke. To correct the situation, you will have to replace it.

In the second case, it is necessary to diagnose levers and gearboxes. In the third - to check what the speed is installed. Perhaps the mechanism works only at a certain speed (by video author - EDS Motor Company).

If water or dirt fell inside the device, perhaps the levers of brushes oxidized and publish strange irritating sounds. In this case, you need to disassemble the mechanism and clean it.

Instructions for replacing the engine wiper

If the electric motor failed and the design for cleaning the glasses does not work, it means that you need to dig deeper and repair the entire system. For this you need first.

The action occurs as follows:

1. Unscrew the nuts, with which lever brushes are attached.
2. Next, you need to remove them from the conical slots of the drive. If they do not succumb to the slots you need to apply a softening agent.
3. To remove the drives of the brushes, you need to turn them out and remove the rest of plastic and rubber parts.
4. At the next stage you need to remove through the slot in motor compartment Wire block.
5. Now the wiper is removed, and then the electric motor.

Usually one glance is enough to calculate what the cause of the breakdown: Perhaps the case in the wires may have oxidized the contacts or other details were out. If the decision to replace the faulty motor is already accepted, it remains only to operate according to the scheme described only in the reverse order, replacing the broken Motor of the VAZ janitors to the new one, good quality. Although we are talking in this article about a certain car, car enthusiasts of other machines, for example, UAZ does not hurt either.

Occasionally, it is necessary to replace the wiper on the rear window.

If you need to dismantle the motor and replace it with a new, act like this:

1. Remove C. rechargeable battery The wire connected to the minus terminal.
2. Release the back door from the upholstery.
3. Remove the lever brushes from the rear wiper.
4. Pull the block with the wiring of the mechanism motor.
5. Out it with the door and dismantle the motor.
6. When all the work has already been done, you need to replace the motor new and collect the design in the reverse order.

Question price

Below in photos you can see prices for the details of the mechanism.

Video "Motor washer with your own hands"

I will immediately say that for all the years of the possession of the "classics" as me, and my father, I do not remember the chance to make a trapezing of janitors with a motor. It turns out that in my case this mechanism has always been quite reliable and never needed to be replaced. If you are lucky a little less, then on the example of your VAZ 2106 I will try to describe the procedure for performing the procedure. And before that, as usual, I will give a list required tools For repair:

1. Horn or combined key on 22
2. End head for 10
3. Ratchet handle with extension

The order of removal of janitors on the "Classic"

The key on 10 or head with the gate turns over one nut of the fastening of each of the janitors:

Then remove the levers together with the windshield cleaners, pulling a little for them to jumped from the slots:

Now we take the key to 22 and turn the trapezoid mount from above:

And take out plastic lining with washers that are visible in the picture below:

Features of the motor removal of wipers and trapezing on the VAZ 2106

First of all, you need to turn off the power plug from the motorcycle janitor. To do this, disconnect it, with a little effort by pulling the ends to the sides:

Now you need to slightly raise the elastic band of the hood seal from one edge, as clearly presented in the photo below:

And then remove the wire with a plug of the slot in the body of VAZ 2106:

Now you can unscrew the fastening of the motor itself, slightly raising the protective case:

After that, pressing on the pins with the slots so that they fall inside. And we try to remove the engine wipers, turning it from side to the side to find the optimal position for withdrawal:

Everything is ready, if necessary, we produce the replacement of the entire mechanism along with the trapezium. Again, I repeat, on very few VAZ 2106 will have to do this procedure, since the whole design is quite reliable.

Wipers (wipers) on VAZ 2107 are of great importance for safety on the road. According to traffic rules, the operation of the car with faulty janitars is prohibited. Therefore, every car owner will be used to know knowledge about the device and the methods of repair and modernization of the janitors.

VAZ 2 wiper device 2107

The wiper system includes:

• motor wipers VAZ 2107;
• electronasus glass washer;
• fuse block;
• relay;
• three-position switch (located on a trigger switch);
• wiper brushes.

Star janitors have two working modes: permanent and intermittent. Modes can be changed by changing the switch position. Intermittent mode is provided by the work of a special relay.

Wiper Fault VAZ 2107

Signs of the fault of the janitors are simple:

• when turned on, the wiper does not work in one and modes;
• when turned on, the wiper does not work at all.

Causes of breakdowns are several:

• defective switch;
• burned fuse;
• bad contact in the electrical circuit;
• faulty engine wiper;
• wiper VAZ 2107 wiper relays.

Note: Often the burned fuse is only a consequence of another fault - damaged isolation in the engine power supply circuit or engine malfunction, as a result of which he starts to consume an increased current.

If the wipers stopped turning on

When the wiper VAZ 2107 stopped working in both positions of the mode switch, start looking for a malfunction with the fuse of janitors. It is installed in an electrical network for its protection against overloads arising from malfunctions, closures or high load on the engine wiper engine. If the fuse is working, you should check its contacts. Often they turn out to be strongly oxidized and prevent the passage of the current. Clear contacts are easy - you need to remove the fuse and clean the contact with a knife, screwdriver or sandpaper. Usually these actions are enough, but sometimes the reason lies in the faults of the relay, switch or engine. But about it below.

If the wipers do not work in intermittent mode

Such a problem is due exclusively with a malfunction of the relay of janitors VAZ 2107. The cyclicity of janitors is ensured by closing / opening the contacts of the relay and, accordingly, the power supply chains of the janitor's engine.

The check should be started with the control of power supply to the relay block. This is done like this:

• remove relays;
• turn on the janitor switch to the intermittent operation position;
• control indicator Check the presence of voltage on the terminal.

If there is no voltage, you need to replace the switch or eliminate the chain break. If the voltage is fed, and the relay does not work, the replacement of the latter is necessary. The design of the relay does not provide for the possibility of repair.

If the wipers stop not at the bottom

Sometimes, when you turn off the bruters, the brothers stops not at the bottom point of the trajectory, but in another random place. The problem lies not in the relay of janitors VAZ 2107, but in the drive gearbox. It has a terminal switch driven by a cam. The cam controls the position of the brushes after turning off the power on the switch lever.

The breakdown of the gearbox is most often happening in the winter when the driver includes wipers that are facing the windshield.

To replace the gearbox, it is necessary to dismantle it with the engine and install a new one.

If the power is served, but the engine does not work

The reasons for which the engine may not work when power supply, several. The most common - cut or wear brushes or failure. Brushes can wear out over time, and can face contacts and break when the relay of the VAZ 2107 janitors is turned on and the power supply to the engine. The winding is most often burning when the engine is overloaded. To check, repair and replacing the gearbox with a wiper engine, it is necessary to dismantle the node from the car.

Removing the gearbox and engine of janitors VAZ 2107

To perform work, there will be a horned or end keys on 10 and 22. The procedure for the following:

After that, you can repair or replace faulty details And set the design of janitors to the place by performing operations in the reverse order.

Relay of wiper VAZ 2107

The wipers "Sevenki" with a strong rain coped with their task perfectly. Problems arise with a drinning rain when the selection of a suitable operation mode becomes a problem. As a result, the wipers are rubbing on dry glass, rubber bands are intensively wearing, and glass can scatter. To avoid this, the driver has to always turn on / off the wipers manually, which distracts from driving.

You can finalize the VAZ 2107 wiper relay, expanding the range of frequency adjustment of janitor.

First you need to remove the relay, which is located in the cabin near the lever of the opening of the hood. To remove, unscrew the two screws and disconnect the block.

Resistor resistance 62 kΩ, installed on the relay board, provides an interval between inclusions of 4 seconds. It should be replaced by a resistor twice as much resistance, which will provide a minimum pause between inclusions of 2 seconds. But it follows the relay fee with only one leg.

In the resulting rupping of the chain, it is necessary to supply the wires with a variable resistor of 100-500 kΩ (one of the wires going to the variable resistor, it is necessary to enter the scene of the second leg "native" resistor, and the second solder to the unclear legs of the constant resistor.

After connecting the variable resistor, close the relay cover, gluing it into place. This will protect contacts and a circuit board from oxidation and damage.

Wires that go to the variable resistor must select sufficient length so that they allow them to install an alternating resistor at a convenient place for the driver, for example, on dashboard "Sevenki".

After installing a tunned wiper relay, it is possible to adjust the interaction of the jacket engine from 2 to 8-10 seconds. Due to this, you can choose the optimal mode corresponding to the rain intensity.
