Wiper drive grant repair

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 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.

Welcome to VAZ Repair!
Today in the “Lada Granta Repair” section you will learn how to replace the Lada Granta windshield wiper drive at home if it malfunctions. “Kalinovody and Grantovody” claim that among the numerous shortcomings or, more simply, “sores” of Kalina and Granta, one can safely include the problem of the windshield wiper drive, the average service life of which is no more than 3-5 years.

These same “sores” manifest themselves in different ways:

Slow speed of wipers;
Failures associated with plastic parts (rods);
Exit of wipers beyond the boundaries of the cleaning area, etc.

The problem is that the price of the trapezoid assembly with gearbox is quite high. Therefore, in case of a problem with lubrication, the gearbox does not have to be changed; it can be disassembled and lubricated; fortunately, there are plenty of instructions on the Internet. The trapezoid is another matter; here, as a rule, replacement is inevitable.

In my case, the problem was the following - during operation, the wipers began to travel more and more beyond the cleaning area, while constantly hitting the frill pillar (a plastic decorative trim at the bottom of the windshield). The decision was made - replacing the Lada Granta windshield wiper drive completely, that is, the entire trapezoid.

Instead of the “native” drive, it was decided to install another one - manufactured by Valeo, they are interchangeable, so they are installed without problems.

In order to replace the Lada Granta windshield wiper drive you will need the following set of tools:

Key to “10”, “13”;
TORX T20;
Screwdriver.

Why wipers may not work on Lada Granta

Incorrect operation of the wipers is included in the list of five malfunctions for which any operation of the vehicle is prohibited, even driving to the repair site. Therefore, you should take the issues of repair and diagnostics of the wiper mechanism very seriously.

Why might the wipers not work?

The most basic reasons why wipers on a Lada Granta may not work.

The steering column switch for the wiper operation mode is faulty.
The contact relay is faulty.
The fuse is faulty.
The wiper mechanism (motor, ramp) is faulty.
Circuit break.

Let's consider each of these reasons separately.

Fuse blown

The most common situation is a blown fuse. Diagnostics should begin with it; to do this, replace the fuse with another one from the mounting block. The number of the windshield wiper fuse in the mounting block is F4. Detailed diagram of the mounting block is here.

The windshield wiper fuse is indicated by an arrow.

The wiper relay has “decided to live for a long time”

If, after replacing the fuse with a known good one, the wipers still do not work, then check the contact relay. The check is the same, it is replaced with a known good one.

Contact relay number K6.

The windshield wiper relay is indicated by an arrow.

Incorrect operation of the steering column switch

The car's wipers only work when the ignition is on. Therefore, if you try to turn on the windshield wiper with the ignition off and nothing happens, then this is not a breakdown!

Do-it-yourself replacement of the Lada Granta windshield wiper drive - step-by-step instructions

1. First of all, remove the wipers. This is done in the following way: it is necessary to remove two decorative plugs, under which there are mounting nuts with a key size of “13”, they must be unscrewed, and the windshield wipers must be removed from the slots along with the brushes and leads.

Note: After removing the wipers, do not turn them on so as not to have to worry about adjustments during assembly.

2. Next, you need to remove the frill (decorative plastic trim), for this you will need an “asterisk” - TORX T20.

Note: Some mounting screws are hidden under decorative caps.

3. Using a “10” key, you need to unscrew the nut (on the right), as well as 2 bolts (on the left) securing the trapezoid.

4. Now you can turn off the power; to do this, disconnect the wire from the battery and disconnect the connector. Now you can safely remove the entire trapezoid assembly.

5. Next, everyone can do their own depending on the need, some will have to replace everything, and for others it will be enough to wash everything and lubricate it properly.

6. After completing all the necessary work, you can perform assembly; it is performed in the reverse order.

The new trapezoid works properly, while the cleaning area has increased (within the limits of what is permitted), it does not rub or touch anything anywhere

Replacement of Lada Granta windshield wiper, windshield wipers, wiper motor

The Grant is equipped with a windshield cleaner and washer.

The windshield wiper consists of a gear motor with rods and two levers with brushes. The supply voltage is supplied to the electric motor of the gearmotor through an additional relay when the ignition is turned on. To protect the gearmotor from overloads, a bimetallic fuse is built into its internal circuit.

To supply washer fluid to the windshield, two washer nozzles are installed on the hood. The liquid is supplied to them by an electric pump through an elastic tube from the windshield washer reservoir mounted on the right mudguard in the engine compartment. The pump is installed on the wall of the tank.

In winter, a special antifreeze liquid must be filled into the windshield washer reservoir.

1. Prepare the car for work and disconnect the terminal from the negative terminal of the battery

2. Using a screwdriver, remove the plug from the windshield wiper arm.

3. Using a 13 mm socket wrench, unscrew the nut securing the windshield wiper arm and remove the arm.

If the lever sits tightly on the shaft splines, then in order not to bend the shaft, place a nut on the threads and use sliding pliers to press the lever off the shaft.

4. Similarly, remove the second windshield wiper arm.

5. Remove the air intake grille

6. Release the holder of the connection block of the windshield wiper gear motor.

7. Disconnect the windshield wiper wiring harness block from the vehicle's on-board network.

8. Using a 10 mm socket wrench, unscrew two bolts 1 and nut 2 securing the windshield wiper.

9. Carefully remove the glass cleaner from the air supply box.

If the windshield wiper is new or has been repaired, the arms should be installed last. Before installing the arms, connect the windshield wiper to the vehicle's on-board power supply and turn on the intermittent operation mode. Once the windshield wiper has completed a full cycle and stops, turn it off. And after that, set the levers in the lower position of the glass. If you cannot install the arms so that the windshield wiper works correctly, you should rearrange the crank on the gearmotor shaft (see below, “Windshield wiper - replacing the gearmotor.”

Types of wipers for Lada Granta

Domestic VAZ models can be equipped with one of three types of windshield wipers:

frame;
hybrid;
frameless.

By default, frame type is installed from the factory, as the most economical option. However, this design is short-lived and ineffective due to rapid wear and deformation under the rays of the sun. The basis of the brush is a metal strip with movable arms and a rubber cleaner.

The hybrid version of the wiper differs from its predecessor in that it is smaller in size and low-slung. The frameless model is made of impact-resistant plastic with a rubber seal at the end.

The non-contact option is considered the most effective, with a long service life and good adaptation to temperature changes.

There is a fourth type of brushes - winter ones. They are designed for use at sub-zero temperatures. The structure at the base is sealed with an additional layer of plastic. There is a special ledge on the surface for removing snow and ice from the windshield.

The method of fixing all four types is “J”-shaped. Previous modifications had an excellent mechanism, which is considered outdated and ineffective.
