Windows: Description and Operation

The circuit breaker applies battery voltage at all times to the power window relay. With the ignition switch in ON or START, fuse 7 applies battery voltage to the power window relay. The power window relay energizes and allows battery voltage from the circuit breaker to the left front power window switch.

Driver's Window
When the left front power window switch is moved to UP, battery voltage is applied to the power window motor. The motor's ground path is back through the left front power window switch to ground G200 and the power window motor drives the window up as long as the switch is held. When the left front power window switch is moved to DOWN, battery voltage applied to the power window motor is in the opposite direction. The motor drives the window down as long as the switch is held.

Auto Down
When the left front power window switch is moved to AUTO DOWN, a signal is sent to the auto down controller. The controller then energizes a coil which holds the switch in the down position. The switch stays in this position until the window reaches the fully open position.

Passenger's Window
The passenger windows can be operated from the left front power window switch or the respective power window switch. The passenger's power window switches can only operate the windows when the lock switch in the left front power window switch is in the OFF position.

When a passenger's power window switch is moved to UP, battery voltage is applied to the respective power window motor. The motor is grounded through the contacts in the respective power window switch and the left front power window switch to ground G200. The window moves up as long as the switch is held in the UP position. If a passenger's power window switch is moved to DOWN, battery voltage is applied to the respective power window motor in the opposite direction. The window moves down as long as the switch is held in the DOWN position.
