The electric drive of window regulators – general information and check of serviceability of functioning

The control system of functioning of window regulators consists of switches of management, the relay, driving electric motors, regulators of window regulators, mechanisms of lowering lifting of glasses and a connecting electrical wiring. Electric motors of the drive of window regulators are located in door assemblies of the car.

Control of window regulators can be exercised from the driver's place by means of the main switch, or by means of manipulations with individual door switches. Each of glasses is equipped with a separate driving electric motor of reversive type. Switching of a command key polarity of connection of the motor and, as a result, the direction of its rotation changes.

The contour is protected by a safety lock and the breaker of a chain. Also individual protection of each of electric motors is provided by own breaker of a chain preventing a possibility of inactivation of all system when jamming separate glass.

The electric drive of window regulators functions only at the included ignition. In addition, on many models the possibility of blocking of window regulators back (and sometimes and a lobby passenger) doors from the main switch is provided. Do not forget about this function when checking failures of the electric drive.

The described checks have the most general character therefore if their performance does not allow to establish unambiguously a cause of failure, drive away the car for more detailed diagnostics on car repair shop.

 PERFORMANCE ORDER

1. In case of refusal window regulators always first of all check a condition of the corresponding safety lock and/or the breaker of a chain. If window regulators of back doors are controlled only from the main switch, check conductivity of the blocking switch in the released state. Replace the faulty switch.
2. Check a condition of an electrical wiring on the site of a chain between switches and the assembly block of safety locks. Make necessary repair.
3. At refusal of functioning of the main switch of only one of glasses, check serviceability of operation of this window regulator from the individual switch.

Told does not belong to a window regulator of a driver's door.

4. If the window regulator works only from one of two switches, check serviceability of functioning of the suspected switch (distribution of provodimost).
5. The faulty switch(es) is subject to replacement. If the switch as it should be, check for break and short circuit a chain on the site between the corresponding switch and a driving electric motor of this window regulator.
6. If the window regulator does not work from both switches, remove the panel of an internal upholstery from this door and check serviceability of giving of food both for the switch, and for the driving motor of the regulator (at the relevant provision of the switch).
7. At correct giving of food on an electric motor separate glass from the window regulator regulator (see the Head Kuzov) and manually move it up-down, checking freedom of movement. Also check serviceability of a condition of the regulator. If the regulator is normal, and glass freely moves in both directions, replace a driving electric motor. At violation of smoothness of movement of components eliminate the found hindrances, grease the rubbing knots and replace the damaged details.
8. If food on the motor does not move, check for conductivity existence an electrical wiring on the site of a chain between switches and motors (in case of need address schemes of electric connections at the end of the present Chapter). If the contour is equipped with the executive relay, check serviceability of a zapityvaniye and grounding of the last. Make sure that the relay regularly gives tension on the included electric motor, in case of need replace the relay.
9. Having made necessary corrections, repeat check of functioning of window regulators.
