11.42. Window regulator electric drive


The electric drive of a window regulator provides lifting and lowering of lateral windows. Its structure includes switches, the relay, electric motors, a window regulator and wires. The reversive electric motor is mounted in each door.

The electric drive turns on or the main switch on a door of the driver, or remote switches on each of doors. Lowering or lifting are regulated by the provision of each of switches.

The chain of the electric drive is protected by a safety lock and a breaker. In each electric motor the individual breaker that at refusal of one drive drives of other windows were not disconnected is in addition mounted.

The electric drive of a window regulator works only at the included ignition. On the most part of cars the blocking switch which disconnects electric drives of other windows except driver's (on a part of cars of only back windows) is provided.

Below the general procedures of search of malfunctions which can be executed independently are described. If with their help it is impossible to eliminate malfunction, address in car-care center.

If window regulators of all windows do not work, at first check a safety lock and a breaker.

If window regulators of only back windows do not work, check short circuit of contacts of the blocking switch. If contacts do not become isolated, the switch replace.

Check a conducting condition between switches and a safety lock, if necessary repair.

If only one window regulator does not work, check the main switch and switches of other windows (except driver's).

If the window regulator works only from one switch, check all switches.
