Power Window System Operation
Fuse #1 supplies B+ to the driver door switch, and the driver and front
passenger window motors. Fuse #7 supplies B+ to the LR and RR window motors.
Ground is supplied to the driver door switch by G200. Ground for the driver
door switch enables the Battery Saver Feature. When any door is opened the
corresponding door jamb switch will send a ground to the driver door switch.
Upon receiving the ground signal the driver door switch will disable all
window motors by removing voltage from the express circuit of the motors.
The driver door and front passenger door switches are located in the
doors. The driver door switch can operate all the windows and includes a rear
window lockout switch. In addition, switches are located in the rear doors
to operate the rear windows. The rear window switches are operational only
when the rear window lockout switch is in the UNLOCK position. All the window
switches send an up or down signal to a motor to operate that particular window
up or down.
