Fig. 15.61. An arrangement of components of window regulators with the electric drive: 1 – the main switch of window regulators located on the driver's door; 2 – ignition lock; 3 – switch of a window regulator of a door of the driver; 4 – safety locks and the relay of window regulators in the block of safety locks and the relay; 5 – electric motors of window regulators of forward doors; 6 – electric motors of window regulators of back doors
The window regulator with the electric drive carries out rise or lowering of glass the electric motor located at doors. The system consists of switches, the relay, electric motors, mechanisms of the window regulators and electric chains connecting all components
Management of rise or lowering of glasses is carried out from the main switch located on a door of the driver or the separate switches located on each door. In each door the reversive electric motor of the drive of window regulators is located. Position of the switch defines polarity of tension given to the electric motor.
Each electric chain is protected by a safety lock and automatic machine of protection (the current relay). Each engine is also equipped with the internal automatic machine of protection.
Window regulators work with the electric drive only at the included ignition.
You make check of window regulators as follows:
If window regulators do not work, first of all check integrity of a safety lock and a condition of the automatic machine of protection.
If window regulators only of back doors do not work or work only from the main switch, check the switches located in back doors and if necessary replace them.
Check an electric chain between the switch and the block of safety locks and the relay and if necessary restore it.
If from the main switch the window regulator only of one door does not work, check work of a window regulator from the switch located on a door.
If the window regulator works only from one switch and does not work from another, check a condition of that switch. If the switch is serviceable, check an electric chain between the switch and the corresponding electric motor and if necessary restore it.
If the window regulator does not work from one switch, remove an upholstery of a door and check presence of tension on the switch and the electric motor at the switched-on switch.
If tension moves on the electric motor, disconnect glass from the window regulator mechanism, manually move glass up and down and be convinced that glass moves easily and without jammings.
Also check a condition of the mechanism of a window regulator. If the mechanism of a window regulator is not damaged and glass moves easily and without jammings, replace the electric motor.
If tension does not move to the electric motor, check an electric chain between the switch and the corresponding electric motor and if necessary restore it.
After elimination of malfunctions check work of window regulators.
