Come on, get moving: why the wipers stop working and how to fix a trapeze

A hot topic for owners of the corresponding model is replacing the windshield wiper trapezoid on a VAZ 2110. Experienced motorists know: this part is subject to rapid wear

, or rather not the part itself, but some of its components. In particular, the bushings are made of plastic. Whether the design is to blame for this, or some other defects, they wear out much faster than other mechanisms.

Meanwhile, the performance of windshield wipers is a guarantee of safety in bad weather.

Replacing the windshield wiper trapezoid on a VAZ 2110 is a necessary measure that has to be taken to maintain the wipers in working condition. At the initial stage, this problem manifests itself in a weakening of pressure - in other words, the windshield wipers cannot cope with flows of water or heavy snowfall. Returning to the original position is difficult; you can actually feel the strain with which the wipers move across the glass.

The presence of such symptoms indicates wear and tear on the trapezoid mechanisms.

Wiper circuit

First, let's try to understand how the windshield wiper circuit on the VAZ 2110 works and what components form a solid unit called a windshield wiper.

1. Remove the plastic plug, unscrew the 2 nuts to “13”, then the wipers with their leads.

1. Remove the frill using a TORX T20 socket. Perhaps some of the bolts will be covered with plugs.

Why the wipers don't work

At some point, the car owner may notice that his wipers are not working. This may manifest itself in their complete stop or creaking operation.

Trapezoid Compatibility

First of all, look for the reason in the electric motor. But remember that mechanical problems also happen.

The most popular mechanical breakdowns of wipers:

• When the cleaners turn on, the sound of the motor is heard, but the brushes do not move or twitch slightly. Most likely, the nut securing the crank to the gearbox axle has lost its grip or has become completely unscrewed.
• Non-synchronous operation of the windshield wipers indicates a problem with the drive. Again, check the locking nut. When tightening the nut, be sure to first place the brushes in the correct position.

As for problems with the electrical component, they manifest themselves as follows:

• The wiper moves very slowly, stops, then starts working again, does not stubbornly go to the lower position. Check the limit switch. By bending the contacts, it is adjusted in this way. If such a measure does not bear fruit, replace the entire VAZ 2110 wiper motor assembly, since the gearbox is built-in;
• You have turned on the intermittent mode, but the brushes work non-stop. Here the problem lies in the relay, which needs to be replaced. If when you turn on the device you do not hear a sound from the rotation of the motor armature, then the relay is 100% to blame. If not, then check for burns and oxidation on the contacts;
• When choosing any mode, you can only hear the clicking of the thermometallic fuse. At the same time, the anchor and brushes remain in place. Check to see if the brushes are frozen because of the frost and that’s why they don’t move. Either fuse F5 has blown, or the armature has burned out;
• The electric motor does not turn on, although the fuses are good. Check the quality of contacts. This often causes a stuck brush or a burnt armature.

If the wipers stop turning on

When the VAZ 2107 windshield wiper stops working in both positions of the mode switch, you should start looking for the fault with the wiper fuse. It is installed in the electrical network to protect it from overloads that occur during malfunctions, short circuits or increased load on the wiper motor. If the fuse is working, you should check its contacts. Often they are highly oxidized and prevent the passage of current. Cleaning the contacts is simple - you need to remove the fuse and clean the contacts with a knife, screwdriver or sandpaper. Usually these actions are enough, but sometimes the reason lies in a malfunction of the relay, switch or motor. But more on that below.

Windshield wiper repair

In practice, repairing wipers on a VAZ 2110 is not at all difficult if you have at least basic experience in working with a car and its electrical components.

Unscrew the fixing nut

First, let's figure out how to remove the wipers on a VAZ 2110. The design provides several fasteners, by unscrewing which you can easily remove the wipers themselves.

But with disassembling the windshield wiper assembly, everything is a little more complicated. It is analyzed as follows.

1. Remove the dashboard.
2. On the left side, find the relay that is attached to the body. If it is broken, there is no point in repairing it. Just install a new relay.
3. Next, check the condition of the fuse that controls the operation of the windshield wiper drive.
4. Disassemble the steering column to allow you to examine the state of the switch. If the insulation is damaged or there is other damage, replace the unit.
5. Unscrew the electric motor from the body and check it in action. If the damage is not serious, it can be repaired. It's better to immediately replace it along with the relay.
6. Check the drive. It is not uncommon for a pulley to break on it, which is why the device has to be replaced with a new one.
7. Make sure the trapezoid is in good condition. It may be necessary to replace the windshield wiper trapezium on a VAZ 2110 if, during operation of the car, the lubrication of the device has deteriorated and all kinds of debris and water have gotten in there. If the lubrication does not work properly, the plastic bushings of the hinges wear out, causing play and increasing resistance during operation of the device. The trapezoid itself serves to transmit force from the electric motor to the windshield wiper arms.

What affects the condition of the trapezius

The main cause of all problems associated with the trapezoid is the location of the mechanism. The wiper motor and trapezoid are located directly under the glass.

Dirt, small abrasive particles, water and washer fluid constantly accumulate in this area.

This leads to wear at the moving joints and loss of lubricant. Active wear of the plastic bushings of the hinges is observed, backlashes appear, resistance noticeably increases during operation and the load on the motor increases. In such conditions, the trapezoid for the wipers and the motor quickly fail.

As a rule, the VAZ 2110 trapezoid requires revision every 2 years. Such an inspection should mean cleaning the trapezoid from dirt and additional lubrication. If this is not done, after 5-6 years the trapezoid will need to be replaced or repaired (a trapezoid repair kit is used).

The wiper motor and trapezoid are located directly under the glass, so some of the water or washer fluid falls on them. In addition to water, dust, dirt and various small debris get there. All this leads to a change in the properties of the lubricant and deterioration in the performance of the trapezoid. When the lubricant loses its properties, the plastic bushings of the hinges begin to wear out, resulting in backlash and increasing resistance during operation.

Alternative solutions

Most car owners of the domestic “ten” are accustomed to replacing worn out and faulty windshield wipers with similar ones.

Often this happens because they do not see alternatives and are not familiar with them.

But this size can be increased to 530 millimeters . It is not recommended to install more, since this way the windshield wiper will not be able to work effectively, and the drive simply will not cope with the load. As a result, too long brushes cause squeaking and jerky work. Plus, don’t count on a long service life of the wiper mechanisms.

The original windshield wipers for the 10 are quite good. But there are more expensive, but also more highly efficient, high-quality devices.

Today it is fashionable to use frameless wipers, especially from Bosch. Their advantages lie in their compactness and a special, reliable leash mechanism.

But as practice shows, on the windshield of the VAZ 2110, as well as other VAZ models, they do not look very nice, because the fasteners on the leash turn out to be massive. Although if you modify them a little, you will get a very good result.

Refinement stages

Wiring
It is easy to modify or replace wipers. To do this you need to take several sequential steps:

• Disconnect the negative cable from the battery;
• Pull the wiper towards you;
• Remove the existing brushes;
• If there is a decorative trim, remove it;
• Unscrew the mounting bolt, thereby removing the old wiper;
• Compare the dimensions of the old and new cleaner;
• Ideally, the new device should not exceed the old one by more than 20 millimeters;
• Reverse the assembly procedure.

As you can see, changing windshield wipers is not difficult. But with the repair procedure, everything is somewhat different. But following the instructions, even an inexperienced VAZ 2110 owner will be able to do everything with his own hands.

The VAZ 2110 is equipped with a three-speed windshield wiper system. The cause of its malfunction may be a gear motor, relays, fuses, a steering column switch, and even a leaking washer reservoir on a VAZ 2110 car. The article discusses the causes of wiper malfunctions and their elimination.

Wipers for headlights

Some owners of “Sevens” install windshield wipers on the headlights for ease of use of the headlights. With the help of these elements, there is no need to constantly clean the optics from dirt manually, which is especially important in rainy weather. To implement the mechanism, the following list will be required:

• headlight cleaner motors 2 pcs. (left and right);
• two transition strips;
• brush leads;
• brushes;
• washer reservoir with two pumps;
• five-pin relay;
• wiring with blocks;
• solenoid valve from the G8;
• tee and washer tube about 2 m.

As for the brushes themselves, they can be installed from both VAZ 2107 and VAZ 2105.

The main elements for equipping headlights with wipers are motors, leads, brushes, a reservoir with pumps, an electric valve, a relay and wiring

Possible causes of wiper malfunction

The causes of windshield wiper malfunction can be either mechanical or electrical. We start troubleshooting first with the fuse, and then we disassemble the rest.

Mechanical problems may include the following symptoms:

1. When the windshield wiper is turned on, you can hear the wiper motor running, but the blades do not move. This may primarily be caused by a loose or loose nut that secures the crank to the gearbox axle.
2. If the brushes do not work synchronously, the reason may be the driver - its fastening nut has become loose.

Electrical faults have the following symptoms:

1. The brushes do not occupy an extreme position, they stop anywhere and move slowly. The cause may be the ring switch. In this case, you need to bend the contacts. If this does not help, you need to replace the wiper motor assembly, as it is sold with a gearbox.
2. The intermittent mode is turned on, and the brushes work continuously, then the problem is in the relay, it needs to be replaced. If the replacement does not help, then it is likely that the contacts on the limit switch have oxidized or burnt.
3. If, when you turn on the windshield wiper, the windshield wipers and armature do not work, then the blades may have frozen. Another reason could be a burnt anchor.
4. The electric motor does not work, but the fuses are good. In this case, it is necessary to check the contacts that the wiper drive has, as well as the motor. It is possible that the VAZ windshield wiper blades are stuck or the armature is burnt out.

Checking the operation of the windshield washer

Recommendations

Often the wipers on the VAZ 2110 begin to work poorly as a result of problems with the electric motor, and not the trapezoid. For this reason, when servicing or replacing the trapezoid, it is important to check the serviceability of the electric wiper motor.

1. To check the wiper motor, you need to disconnect it from the trapezoid by unscrewing the mounting nut. The motor is then connected directly to the battery or via a standard power connector. A low buzzing sound during operation is considered normal. At the same time, noise, grinding and crackling when power is supplied are unacceptable. We also recommend reading the article on how to replace windshield wiper blades. From this article you will learn about the features of replacing wiper rubber bands, as well as what you need to consider when performing this procedure.
2. Experts also recommend turning on different operating modes so that the engine as a whole runs for about 10 minutes. Next, you should feel the motor. Strong heating will indicate that the wiper motor will soon fail and needs to be replaced. It is also possible to repair the motor, but it is easier and faster to purchase a new device, since its cost is not high.

Finally, we note that the VAZ 2110 windshield wiper requires regular trapezoidal maintenance. At a minimum, cleaning from dirt and lubrication is necessary. This allows you to significantly increase the service life of the mechanism and reduce the load on the electric motor, increasing its service life and productivity.

Windshield wiper repair

To repair the unit you will need the following materials and tools:

• set of sockets and keys;
• screwdrivers;
• WD-40 liquid;
• old rags;
• trapezoid repair kit in case of need for replacement or windshield wiper repair kit for VAZ 2110;
• other parts requiring replacement.

To repair the windshield wiper, you need to disassemble it:

1. First you need to remove the instrument panel.
2. Next, you should find the VAZ 2110 wiper relay, which is screwed to the body. If it doesn't work, it needs to be replaced.
3. It is advisable to remove the frill so that it does not interfere with disassembling the unit.
4. Now you need to check the fuse that is responsible for the operation of the VAZ 2110 wiper drive.

The next step is to disassemble the steering column to check the switch. If it has significant damage, it needs to be replaced (the author of the video is “In Sandro’s Garage”).

1. Next, you need to dismantle the motor and check it. If replacement is necessary, replace the windshield wiper motor and gear motor assembly.
2. If the windshield washer reservoir or pump is damaged, it must be replaced.
3. Be sure to check the size and condition of the brushes: they must meet the standards specified in the manual. Their length is important as they must cover the entire surface of the windshield.

Do-it-yourself modification and replacement of wipers

Which wipers are better is up to the car owner to decide. Those installed on the VAZ 2110, as well as on the UAZ, do their job well from the factory, but it can be modified with washers from other companies that are of higher quality. Many people are attracted to frameless brushes - this is a good option. They are compact in size and equipped with a special leash mechanism. True, they do not look very attractive on the VAZ 2110, since the fastener to the standard washer arm turns out to be massive. Therefore they need improvement.

Frameless car washers

To perform a replacement or modification, you must perform the following steps:

1. First you need to disconnect the negative terminal on the battery.
2. Then you need to tilt the mount towards you and remove the brush.
3. If there is a decorative trim, it must be removed.
4. By unscrewing the bolt, you can remove the old brush.
5. Before replacing parts, be sure to check the dimensions of the new washer with the old one. It is advisable that the new one does not exceed the size of the old one by more than 2 cm.
6. Installation of the new kit is carried out in the reverse order.

After upgrading, you should check the functionality of the unit: whether the brushes creak, how they work when switching modes. At high speeds of the windshield wiper motor, the wipers should work quickly, at low speeds - slowly. In addition, they must support intermittent operation.

Replacing the trapezoid

The replacement process is simple, but it involves manipulations that require increased attention and accuracy - there is a danger of damage to neighboring components and mechanisms.

We de-energize the car by removing the “negative” terminal. We remove the special wind cover (the so-called “jabot”) and the expansion tank. The latter must be removed at an angle - there is a possibility that some of the coolant will spill out, so it is useful to first drain some of it into a previously prepared container.

Then you need to turn off the gearmotor

. To do this, remove the corresponding connector. Carefully pull out the trapezoid (depending on the year of manufacture, it can be attached to two or four studs) and carefully remove it from the air supply box. That's it, the work is completed.

Installation of a new trapezoid is carried out in the reverse order.

How to remove the windshield wiper trapezoid

To remove the trapezoid you will need:

• key to 10;
• thin flat screwdriver;
• crosshead screwdriver.

First of all, you need to remove the wipers. To do this, you need to remove the plastic pads and unscrew the nuts with which they are attached to the trapezoid studs. Then unscrew the screws and side fastenings of the protective casing (jabot) and remove it. If the fasteners do not come out, treat with WD-40. Before removing the casing, make sure to remove all screws, bolts and nuts. If the cover does not come off, look for a fastener that you did not remove. Lifting the frill, disconnect the washer fluid supply tube from the tee, and then move the casing to the side.

Remove the belt that supports the radiator tank and move the tank to the side. Then pull out the partition (sound insulation), which is located behind the tank. Don't forget to remove the washer fluid supply tube from it. Disconnect the electric motor power connectors. After this, unscrew the bolts securing the trapezoid and electric motor. To remove the trapezoid, you must either struggle for a long time, coming up with various options, or place a thin flat-head screwdriver under the far end (relative to the motor) of the lower rod of the trapezoid and pull out the entire structure as if on a slide. You can also turn the left edge of the trapezoid clockwise and pull it out, then remove the engine.

Putting the trapeze in place

Usually, installing the trapezoid into place does not cause difficulties. Insert it and secure with bolts. Do not overtighten the motor mounting bolt; the motor may need to be turned slightly to get the trapezoid to operate smoothly. After making sure that the trapezoid is working properly, tighten the electric motor mounting bolt, install and secure the sound insulation, frill (do not forget to connect the washer tube), and the expansion tank. Insert the plastic plugs and install them in place, install the arms with brushes and check the operation of the wipers in all modes.
