How to set up wipers on a Priora

How to speed up the work of Priora wipers

The problem of slow windshield wipers appears over time. The speed may decrease several times; the windshield wipers begin to move slowly even on wet glass covered in rain. There are three reasons for the malfunction:

• engine malfunction;
• poor performance of wiper hinges;
• problems with the engine power supply.

Motor malfunction may be due to worn brushes or bearings. But the wiper motor is quite reliable, so more often the reason is in the hinges or power supply.

The operation of the hinges can be adjusted using high-quality lubricant. To do this, you need to remove the trapezoid with the motor, wash the hinge joints and apply a lubricant that does not thicken at low temperatures.

Power supply problems are solved by updating the Priora windshield wiper circuit. The wiper switch circuit contains many electrical connections and contacts that oxidize over time. As a result, there is a drop in the voltage supplied to the wiper motor, and it does not develop the required power.

Modification of Priora wipers by installing a five-pin electromagnetic relay, which minimizes current losses in the power circuit.

For this you will need:

• 5-pin relay - 3 pcs.;
• 5-pin relay motor connector;
• round terminals - 5 pcs.;
• wire with a cross section of 2.5 mm.

The connection diagram involves installing three relays in the wire gap in front of the windshield wiper motor and does not make changes to the standard car wiring (Figure 1). As a result, the voltage supplied to the engine through the contacts and switches of the wipers only controls the activation of the relays, which supply the on-board network voltage to the engine without loss.

Particular attention should be paid to the insulation of the contact wires. The relay unit must be installed in a suitable plastic case and the holes sealed to prevent moisture from entering, which can cause oxidation of the contacts and damage to the relay.

This solves the problem of slow operation of the wiper motor.

When using the Priora windshield washer, the wipers make four passes instead of two, as on most cars. The first two cycles the wipers scrape dirt and water from the glass, and the last couple of cycles the wipers move over dry glass. As a result, accelerated wear of the rubber bands occurs, and scratches appear on the glass. This “bug” can be corrected by modifying the Priora windshield wiper. It consists of modifying the windshield wiper relay, after which the number of strokes will decrease.

The work requires minimal skills in handling a soldering iron in order to be able to replace one resistor in the relay.

To upgrade the wiper relay you will need:

• resistor 40-70 kOhm;
• screwdriver or knife;
• soldering iron;
• solder;
• rosin.

The number of movements of the wipers when the washer is turned on depends on one of the resistors in the relay circuit. Its resistance is 141 kOhm, and for two cycles a resistor of approximately 51 kOhm is required.

To upgrade the relay, you must perform the following steps:

• remove the wiper relay from the fuse panel;

• use a knife or screwdriver to open and disassemble the relay;
• heat the soldering iron;
• remove resistor 140 km;

• solder a 40-70 kOhm resistor onto the vacant space (with higher resistance, the wipers can make 3-4 strokes instead of 2);

Note: If a resistor of a suitable value is not available, you can replace it by connecting resistors of a suitable value in series or in parallel. For example, solder two 20 kOhm resistors connected in series (you get 40 kOhm) or two parallel connected 100 kOhm resistors (you get 50 kOhm).

• assemble the relay housing;
• install the relay on the fuse panel;
• Check the functionality of the relay by briefly turning on the glass washer.

The modification of the Priora windshield wiper has been completed. The wipers will perform two strokes.

You can also install an additional pause regulator between wiper movements based on a variable resistor. For this you will need:

• wires;
• male and female connectors;
• variable resistor.

To install the regulator, you must perform the following steps:

• solder two wires to the resistor;
• install male and female connectors at the ends of the wires;
• disassemble the steering column casing;
• find the yellow wire with a green stripe;
• pull out the wire connector from the block;
• connect one wire coming from the variable resistor to the block, the other to the tip of the yellow-green wire disconnected from it;
• attach the variable resistor in an accessible place (for example, on the steering column);
• assemble the column casing.

Such modification of the Priora wipers is not feasible on luxury cars equipped with rain sensors.

How to turn on the wipers on a grant

Skip to content

The quality of road visibility is one of the key factors in safety and accident prevention. Almost every third driver faces the problem of poor-quality windshield/rear window cleaning.

In sunny weather this is not as important as in rain, fog, snow, when every second counts. The most common defect is the formation of “islands” of dirt in the center and edges of the windshield. When driving in a straight line, visibility is not hampered, but when you start to turn, you feel all the “charm”. There is only one solution to the problem - replacing the Grant liftback wipers, even despite the actual absence of defects or damage.

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.

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

In what cases should windshield wiper blades be replaced?

• Mechanical damage;
• Negative consequences of an accident, collision, impact;
• Deformation from the rays of the sun, contact with a chemical reagent on the surface;
• Defect, manufacturing defect;
• Personal initiative of the owner to modernize and tune the car.

Common reasons why Granta liftback wipers do not work

1. Long-term operation without intermediate preventive maintenance, which led to excessive wear of the rubber base;
2. Purchase and subsequent installation of low-quality, non-original components;
3. Damage to the windshield, which resulted in deformation of the windshield wiper.

Dimensions of Granta liftback wipers

*prices are as of September 17, 2018.

The given prices are for budget components; when purchasing products from famous brands, the cost increases.

Where is the wiper relay located on the Granta liftback?

Many motorists are faced with the fact that their windshield wipers periodically stop working properly, suddenly turning on or off. In 95% of cases, the reason lies in the relay - regulator. It is located under the dashboard on the left side. For access with subsequent replacement, you will need to unscrew the plastic cover and remove the relay. Next, replace it with a new one and close the plastic case again.

The Grant liftback rear (front) wiper relay has several pause modes. This is very useful for reducing the frequency of cleaning when there is light rain. The pause range varies from 1 to 65 seconds. The driver independently regulates the most optimal mode. Catalog number: 723.3777. The product is completely identical to the relay on the VAZ, Priora, Kalina, Kalina 2 models. On VAZ models produced before 2001, a relay with four contacts is installed, unlike the new ones, which have six.

Preparatory stage for replacing windshield wipers

• key to “10”;
• new brushes;
• liquid for removing rust on threads WD - 40.

Step-by-step instructions for replacing wipers yourself

Front

1. We place the car on a level platform, squeeze the handbrake, turn off the engine;
2. Using a “10” wrench, we unscrew the nuts on the rods of the glass holders one by one, and remove the brushes;
3. We carry out preventive maintenance of splines, inspect their condition and integrity, and make a decision on the advisability of replacement;
4. install new cleaners, screw the nuts again.

How to stop constantly running wipers?!

Good day to all! People help! When the ignition is turned on, the front wipers constantly work. The wiper intensity switch works, but cannot be turned off. I pulled out the fuse, I'm driving without wipers and without windshield washer for now because everything is connected to one fuse. Hellp, who has encountered such a glitch! It’s already spring outside, everything is running and melting, there’s enough clean glass for 100m, without wipers and washers it’s a complete mess. As I understand it, there is a short somewhere, most likely water got in somewhere. I can’t catch up, maybe someone had something similar. Tell.

Take the steering column switch apart and clean it, it should help

Put the toggle switch on and it’s like on an airplane: click and the brushes work
