Installation of headlight cleaners (headlight wipers) on VAZ-2107, 2105 and 2104

Operating principle

On a VAZ 2107 car, the wipers are driven by a 12 V electric motor. A relay is installed in the windshield wiper activation circuit. It is responsible for the intermittent operation of the wipers, which work without interruption or at intervals of four seconds.

The windshield wiper is connected in parallel through the contacts of the closer. They are located in the gearbox housing and are “responsible” for returning the brushes to their original position and abruptly stopping the motor. The driver controls the operating mode of the windshield wiper using the switch. The whole mechanism works thanks to a motor. It is prohibited to operate a car with faulty wipers, so car owners must ensure that they are in good working order. And in bad weather, driving with non-working wipers is very dangerous!

Technical side of the issue

How to modify the wiper relay?

Let's start with why this is needed at all. In heavy rain, the classic wipers cope very well, and the speed is quite decent. But when the rain is lightly drizzling, thousands of “classic” drivers scold the plant for the fact that it is impossible to select the required frequency of operation of the windshield wipers. And so, it turns out that they work on dry glass for a long time, which is not good. To avoid this unpleasant phenomenon, you have to turn the wipers on and off manually.

Many will say that there is nothing complicated there - turn it on/off, yes, I agree, but if you drive at least 100 kilometers, your opinion will change.

Why does the windshield washer not work?

All washer malfunctions are divided into two groups: electrical and mechanical.

Mechanical:

• Lack of liquid. In winter, you cannot use ordinary water, as it may freeze. If the water still freezes, you need to warm up the car engine and leave it in a warm room.
• The fluid supply hose may fly off or become pinched.
• The nozzles can also stop the washer from working. Poor quality of water and washer fluid leads to the fact that the fittings become clogged with dirt, rust, and washer fluid does not flow. The injectors are cleaned or new ones are purchased.

Electrical:

• Fuse F2(10A) has blown.
• The electric motor does not pump, no fluid flows, which means the terminals are oxidized. You need to clean the terminals and contacts and connect everything.
• Faulty switch. If the motor does not turn when voltage is present, then this is the reason.
• Check the pump motor by connecting it directly to the battery; if it starts spinning, then the fault is in the steering column switch.

If the wipers do not work intermittently

The test should begin by monitoring the power supply to the relay block. This is done like this:

If there is no voltage, it is necessary to replace the switch or repair the open circuit. If voltage is supplied but the relay does not work, the latter must be replaced. The design of the relay does not provide for the possibility of repair.

Sometimes when you turn off the wipers, the brushes stop not at the lowest point of the trajectory, but in another arbitrary place. The problem lies not in the VAZ 2107 wiper relay, but in the drive gearbox. It contains a limit switch actuated by a cam. The operation of the cam controls the position of the brushes after turning off the power on the switch lever.

To replace the gearbox, you must dismantle it along with the engine and install a new one.

There are several reasons why the engine may not work when power is applied. The most common are shearing or wear of brushes or failure of windings. The brushes can wear out over time, or they can freeze to the contacts and break when the VAZ 2107 wiper relay is turned on and power is supplied to the engine. The winding most often burns out when the motor is overloaded. To check, repair and replace the gearbox with the windshield wiper motor, it is necessary to remove the unit from the vehicle.

To perform the work, you will need open-end or socket wrenches for 10 and 22. The procedure is as follows:

After this, you can repair or replace the faulty parts and install the wiper structure in place by performing the operations in reverse order.

The 7 wipers do their job perfectly in heavy rain. Problems arise during drizzling rain, when selecting a suitable operating mode becomes a problem. As a result, the wipers rub against dry glass, the rubber bands wear out intensively, and the glass can be scratched. To avoid this, the driver has to constantly turn the wipers on/off manually, which distracts from driving.

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

A 62 kOhm resistor installed on the relay board provides a 4 second turn-on interval. It should be replaced with a resistor of half the resistance, which will provide a minimum pause between switching on of 2 seconds. But it should be soldered onto the relay board with only one leg.

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

After installing a tuned wiper relay, it becomes possible to adjust the interval between turning on the wiper motor from 2 to 8-10 seconds. Thanks to this, you can select the optimal mode corresponding to the intensity of rain.

Principles for choosing a courier service

Determine what tasks the courier service should solve. Delivery of clothing and furniture are different. In the first case, additional services such as fitting or partial return of the order will be required, and in the second we are talking about large-sized goods, which will require a loader and a large car to carry. Therefore, consider the additional services that buyers will require.

Match delivery promises with your resources—are there people who will take the order, prepare it for shipping, and package it?

The ideal type of delivery is when the delivery method is suitable for the ordered product, and the site offers a service that is available in the client’s city, within a time frame that is suitable for him, which you and the service provider are able to provide.

There are six delivery types in total:

• "Post office",
• courier,
• express courier,
• courier transport company,
• parcel lockers,
• pick-up point.

"Post office"

At the same time, Russian Post has a very long delivery time, and its delivery times are often not met. There are no additional services - the buyer will not be able to try on clothes and refuse part of the goods. The percentage of non-repurchase of orders is high.

There are several ways to work with Russian Post: you can send parcels as an individual or enter into an agreement. If you don’t want to go to the department for every parcel, you can contact special companies that will pack the goods, send them via mail, and find out the tracking number. Most often, the last method is the easiest, but such work costs extra money.

Express delivery

The main advantage is the possibility of delivery to the door and greater efficiency. Depending on the specific company, there may be additional services, including fitting or partial purchase of the order. Compared to Russian Post, the failure rate for courier delivery is lower.

Urgent courier delivery

It will be needed to satisfy the most demanding customers. The main disadvantages are the high cost and the high risk of refusal of the goods if the courier violates the delivery deadlines.

Pickup points

This type is similar to Russian Post, but with several differences: the delivery geography is smaller and such points are usually provided by commercial companies. The buyer is not tied to time - he will pick up the parcel when he has free time. Sometimes additional services are available.

At the same time, the percentage of unpurchased orders is higher than when delivered by courier service. If the network of pick-up points is small, then this method will be ineffective: it is easier for the buyer to go to the Russian Post and stand in line there than to go to the other end of the city.

Parcel terminals

A relatively inexpensive delivery method with a wide selection of points in major cities. True, you will have to refuse additional services, and the size of the parcel will be limited by the size of the cell.

VAZ 2107 wiper malfunctions

Replacing a burnt out motor

During the winter season, at sub-zero temperatures, wipers often stick to the windshield. The wiper motor is under a lot of load, and it burns out if the bimetallic fuse does not work or the fuse burns out.

Location of the glass cleaner and washer fuse in the mounting block

In such cases, it is necessary to replace the motor. To do this, you need to remove all the parts in a certain order:

• Unscrew the fastening nuts;
• bend the lever and remove it from its seat;
• Using a 22mm wrench, unscrew the trapezoid fastenings on both sides;
• remove the plastic inserts;
• remove the hood seal;
• remove power from the windshield wiper motor;
• remove it with the drive from the hole in the body;
• bend the protective cover, unscrew the fastening nuts;
• press on the protrusions of the slots on the reverse side, on which the wiper arms sit, so that they fall inward, move in different directions, the trapezoid with the motor will come out.

Types of delivery services

Different delivery services usually differ in the cost of services, limiting conditions, services for the client and recipient, as well as possible brand and reputation.

Local companies

Example: “Cubex”, “Turtle”.

They provide extended service in the cities where they operate, but deliver orders only in a specific city and nearby settlements. This is often offset by the low cost of services.

Regional companies

Example: TopDelivery, MaxiPost.

Such companies are ready to change conditions to suit clients and focus on good service. As is the case with local services, they have a small delivery geography.

When comparing courier services, use the table proposed by Gleb Nikulin:

Aggregators

Example: Checkout, Sheepla.

Where does which wire go, or just a diagram

Connecting wipers and washer

“Plus” power is supplied from the ignition switch through fuse No. 2 at 10 Amp of the mounting block. The permanent “plus” goes along the black and yellow wires to contacts “4” of the connectors of the gear motor and the steering column switch. It should not disappear even when the switch is in the “off” position. The blue wire supplies “+” 12 V power to the motor when the switch is in “continuous mode” position. On the blue-white wire, in the “off” position there should be a “minus”, and in the “continuous mode on” position the “minus” is turned off. This is done to slow down the motor when the power to the closer is turned off.

The red wire supplies the relay with “+” 12 V from the switch when the intermittent mode is turned on. At the moment of operation, contacts “2” and “4” close, and “1” and “3” open, the motor starts working and the brushes make one or two movements. Then “+” 12 V is turned off, and contacts “1” and “3” are closed to each other and to “minus”. The motor stops for a few seconds and then the cycle repeats.

The washer pump motor is connected to “+” 12 V constantly with a black and yellow wire through the same fuse No. 2. “Minus” is applied when you press the windshield wiper lever from bottom to top.

The procedure for repairing a windshield wiper is removing and installing a gearbox with a motor:

Repair of VAZ 2101 windshield wiper, disassembly and assembly

The procedure for repairing the VAZ 2101 windshield wiper

1. unscrew the wiper blades with holders;
2. disconnect the wires from the windshield wiper motor and the terminals from the battery;
3. remove the equalizers by first unscrewing the nuts securing the lever fittings;
4. dismantle the windshield wiper assembly, first unscrewing the nuts of the motor bracket;
5. Perhaps a workbench will help you to remove the gearmotor from the mounting bracket, and then disassemble the lever drive;
6. Installation of the windshield wiper after repair is carried out in the reverse order.

After you have repaired the windshield wiper , you need to connect it so that it makes several working cycles. The wiper blades must be installed (in the lower position) – 50 mm from the glass seal. After complete assembly, we check what we have achieved and, if necessary, make adjustments.

Below we will look at how to disassemble and then assemble an electric windshield wiper motor and its gearbox.

Dimensions

Thanks to the small size of the brush, you can save money. The length is identical for all positions. It is 340 mm. It is possible to install longer brushes. At the same time, they will not touch the body. The degree of cleaning of the windshield directly depends on the quality of the brush itself. You need to familiarize yourself with the characteristics in advance.

Original articles

Initially, only original parts were produced for the car. The year of release of the first car from the assembly line is the distant 1982. No imported parts were used. But it is not possible to find original components for installation on a VAZ 2107. After the collapse of the USSR, the release of this series continued.

But AvtoVAZ no longer produced such small parts as windshield wipers on its own. Finished products were purchased abroad, from third-party companies. As a result, assembly is significantly simplified

At the same time, it is important to understand that the quality of original wipers does not differ from products from third-party manufacturers

Original articles:

Replacement options

You can easily purchase wipers from third-party manufacturers. Moreover, their quality will be at a high level. Most famous brands monitor their reputation

It is only important to avoid buying counterfeits. For example, many of them are present at the Bosch company

You can easily identify a fake. It has poor quality packaging. There is no special hologram.

All wipers on sale can be divided into categories:

• frame;
• frameless;
• hybrid;
• winter.

All modifications without exception have their advantages and disadvantages. You need to choose a certain category based on the operating conditions of the vehicle and the region where it is located. Driving style and speed are definitely taken into account.

Frame

The classic type of construction has a metal frame. As a rule, frame wipers are the cheapest. They have advantages: durability, accessibility. Usually the price for a pair starts from 500 rubles. The disadvantage is the aerodynamic shape. As a result of air resistance, the contact strength of the windshield and wiper is reduced. Which leads to poor cleaning.

Frameless

Have less resistance to air flow. Therefore, they can cope with cleaning the windshield at any speed. They have a more presentable appearance than frame ones. Less durable.

The cost is an order of magnitude higher than the price of classic ones. Suitable for all drivers without exception. Regardless of driving style. They have a large contact area.

Hybrid

They are free from the disadvantages of frame and frameless brushes. They are a single piece of rubber. But there is a metal structure inside. Which makes the brush more durable.

Resistance to the air flow flowing around the car is minimal. Easy to use at any speed.

Winter

Winter wipers are distinguished by their elasticity - even at sub-zero temperatures they clean the glass well. The characteristics are achieved by adding rubber to the rubber from which the wiper is made. It retains its elasticity and is not subject to deformation. Easily tolerates strong temperature changes

This is especially important for regions with low average annual temperatures. Optimal choice:

• the temperature at which the car is operated;
• maximum speed - at which the movement is carried out;
• intensity of precipitation.

How to choose wipers for your car: overview of the most popular queries

Does your windshield not clear after just a few swipes of the wipers? Does it leave dirty streaks and streaks? Does the annoying squeak of brushes make you shudder? All these are clear signs of wear on the working part of the windshield wipers - the rubber plates. They become unusable when exposed to the sun in summer and snow and ice in winter. Run your finger along the elastic - if the edge is jagged or uneven, it's time to think about replacing it.

What do motorists do when they need to replace their wipers? The most inexperienced ones turn to a car service. For example, when undergoing annual maintenance, they are asked to include brush replacement in the list of work. Someone is trying to figure out this issue themselves: reading forums and thematic groups on social networks, looking for advice from “VAZ drivers”, “Solaris drivers”, “Pyzhevodov” and other fellow car owners. They ask which wipers to buy for Solaris, Ford Focus, Kalina, Kia Rio and other models. You can spend all day on the Internet looking for answers. Or you can spend 5 minutes on our article and find out the wiper parameters for your car. We have collected the most popular queries by brand and model. Surely you will find yours among them.

Find out the type of fastening

To install new wipers, you need to know how to attach them to the arm. The most common is a hook . It is used on most domestic and foreign cars, for example, on VAZ models starting from the tenth generation. The same wipers are used on Hyndai, Kia, Toyota, Daewoo, etc. It is important to remember that the hook size may vary. You can remove the windshield wiper and measure it. The most popular sizes: 9x3 and 9x4 mm. Another type of fastening is a pin lock , found, for example, on classics.

Foreign cars have more varied fastenings, because large concerns are trying to make most of the spare parts unique. Here are some of them:

• button – found on Volvo, Renault, Ford, Citroen, VW;
• side pin - present in car models starting from 2005: VW Jetta and Passat, BMW 3, some Peugeot, Volvo, Mercedes models;
• side clamp - found mainly in European models Audi, Fiat, Saab, Opel;
• bayonet lock - found on Renault models since 2004, as well as on Saab models.

These and other mounting options are shown in the images.

Types of wiper mounts

Many manufacturers of car windshield wipers include several fasteners in the kit so that the buyer does not have problems with installation. For example, one set of wipers will fit both Polo sedan and Kalina.

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, simply 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.

Table with examples of Russian cars

The table shows the factory parameters. But many owners of Russian cars replace the standard blades with longer ones, since those installed by the manufacturer do not reach the edge of the windshield. For example, wipers on Vesta can reach 61 and 48 cm for the driver and passenger sides, respectively. It might seem like just a couple of centimeters, but they make a big difference. As motorists note, the cleaning radius increases, and there are fewer dirty streaks on the sides of the windshield. If you want to install longer blades, then measure not the actual length of the blades installed, but the part of the windshield in which the wiper will be provided with free movement.

Signs of trouble

If the car refuses to move, problems arise with electrical appliances or electrical wiring, this gives rise to troubleshooting by replacing faulty elements.

If the car does not start, first of all you need to check the flow of fuel into the carburetor or fuel injector frame.

If fuel is supplied, then the problem of the car’s refusal to drive must be looked for in the electrical system using an electrical diagram:

1. For a car with a carburetor, problems may arise with the distributor, coil, spark plugs, and also with electrical wiring. After checking the electrical circuit elements for serviceability, you need to replace the non-functioning components.
2. In a car with fuel injection, the problem may be due to a failure of the ECM (electronic engine management system). Thanks to it, signals coming from sensors are processed and commands are transmitted to units for execution (the author of the video is Alexander Skripchenko).

Problems are possible due to burnt contacts in the ignition switch. To troubleshoot, you need a diagram of the electrical equipment of a VAZ 2107 car indicating the elements that are consumers of the contact group.

Also check out

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.

We repair the device

In the VAZ-2107, the switches are located under the steering wheel of the car. If you suspect a malfunction, the first thing you need to do is find out the reason why this or that function does not work.

Repairing the switch

We remove the steering column switch on the seven. Having removed the first ring, then the headlight, stop and wiper levers, we get to the mechanism by which the turns are automatically turned off. We take it out and here lies the cause of all the troubles: between the reeds there is a spring that breaks off and does not move the reeds in different directions. It is necessary to replace the spring; you can use a regular spring from a ballpoint pen. Next, we begin collecting all the rings and levers in reverse order. After finishing the work, we check how the levers and the turning mechanism work. To do this, we connect the pads and place the terminals on the battery; if all functions work, then we have completed the repair.

Also, the cause of a malfunction of the turn switch may be contamination or oxidation of the contacts. You can clean dirty or oxidized contacts; to do this, you need to slightly bend the “sagging” springs and other accessible parts. As a rule, after carrying out such cleaning manipulations, it is possible to restore the functionality of the switch.

Nuances of delivery from an online store

Delivery times vary from company to company, please take into account some nuances. For the region in which the store is physically located, delivery within 1-2 days after the day of order is acceptable. Outside of large cities, depending on the cost and type of delivery, the buyer receives the parcel within a period of 3−9 days or 1−3 weeks. Perhaps deadlines are not critical for some clients if they can pay less for it. Offer buyers options.

Check what days the service delivers orders and whether they work on weekends. If your target audience is residents of business centers, you can send goods to them on weekdays, but if you sell garden supplies, then the courier will have to work on weekends.

Check delivery hours: some clients need their order in the evening, when they have already returned home from work, because they cannot tear themselves away from production.

Delivery interval is important. The courier service can arrive either exactly on time or throughout the day. In the second case, check whether the courier calls the buyer in advance.

Please clarify what the service means by the stated period - delivery to the recipient or only to his city.

Reasons for increasing delivery times

Delivery times may increase depending on the time of application with customer addresses. If the service collects applications before 18:00, then the client who bought the product at 18:01 will receive it only after 2-3 days, even if he lives on the next street.

Some courier services prefer to coordinate delivery with the client - this requires a preliminary call, which increases the delivery time.

Weight and dimensions

Find out what the minimum billing weight is - usually one or two kilograms. Size restrictions apply. As a rule, if an item weighs more than 30 kg and is more than 150 cm in length, the service will require you to pay extra for oversized delivery.

Find out if the price includes:

• VAT
• door delivery,
• Additional services.

Replacement

The process of replacing the wiper on this car does not cause problems. It is carried out in two stages:

• install the wiper arm in a vertical position - perpendicular to the windshield;
• Carefully, squeezing the plastic fastener on both sides, wiggle the wiper away from the hook.

If you no longer plan to use a used wiper in the future, you don’t have to stand on ceremony with it. And pull it out with a jerk

If the driver plans further use: all operations must be performed carefully. Plastic becomes brittle from prolonged use in the sun

Temperature changes make it fragile. If possible, replacement should be carried out at above-zero temperatures: the likelihood of breaking fragile plastic will be reduced to a minimum.

High-quality wipers that perform their function well are the key to good visibility. Therefore - road safety

It is important to promptly change windshield cleaning blades. This will help you avoid accidents and other problems on the road.

Advantages of BREMAX brushes:

1. The company uses ONLY NATURAL RUBBER WITH GRAPHITE
   to eliminate noise and reduce friction between the brush and glass, and as a result, we get an increased service life of both products.
2. THE CURVATURE AND HARDNESS of BREMAX brushes have been INCREASED
   compared to conventional frameless brushes for better adhesion to the glass and uniform cleaning.
3. The brushes are made of materials that are resistant to all existing anti-ice reagents and to all existing Russian 'anti-freeze' agents.
4. The best quality/price ratio in the segment.

VAZ 2107 windshield wiper malfunctions

Signs of faulty wipers are simple:

• when turned on, the windshield wiper does not work in one mode;
• When turned on, the windshield wiper does not work at all.

There are several reasons for breakdowns:

• switch is faulty;
• fuse burned out;
• poor contact in the electrical circuit;
• The windshield wiper motor is faulty;
• The VAZ 2107 windshield wiper relay does not work.

Note: often a blown fuse is only a consequence of another malfunction - damaged insulation in the motor power supply circuit or a malfunction of the motor itself, as a result of which it begins to consume increased current.

General disadvantages

The main signs of a malfunction of the VAZ 2109 wipers:

• The wipers stop completely, there is no reaction to pressing the levers;
• Brushes do not work periodically;
• The wipers are slow;
• The movement of the brushes does not correspond to the mode turned on in the cabin.

The most common malfunctions of VAZ 2109 wipers:

• Contacts are oxidized;
