DESCRIPTION
 
The power window system allows each of the door windows to be raised and lowered electrically by actuating a switch on the driver’s door trim panel. The front window switch allows the front occupants to lock out the individual rear switches from operation. The power window system receives battery feed through a circuit breaker in the fuse block, only when the ignition switch is in the ON position.

DESCRIPTION

The power window system allows each of the door windows to be raised and lowered electrically by actuating a

switch on the driver’s door trim panel. The front window switch allows the front occupants to lock out the individual

rear switches from operation. The power window system receives battery feed through a circuit breaker in the fuse

block, only when the ignition switch is in the ON position.

The power window system includes the power window switches on the driver’s door trim panel, passenger door and

rear doors, the circuit breaker in the fuse block, and the power window motors.

OPERATION

The front and rear window lift motors are of the permanent magnet type. A battery positive and negative connection

to either of the two motor terminals will cause the motor to rotate in one direction. Reversing current through these

same two connections will cause the motor to rotate in the opposite direction.

Each individual motor is grounded through their respective switch.
