Front Window Operation
WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
When the ignition switch is in the RUN position and the driver window switch on the master window switch assembly is pressed to the down position, voltage is applied to the window motor causing the driver window to open. When the driver window switch is pressed to the up position, voltage is applied to the window motor in the opposite direction. The driver window closes. The return path to ground is supplied through the inactive control circuit being normally grounded through the master window switch. The front passenger window operation is identical to the driver window operation.
The master window switch also controls the LR, and RR windows. Refer to rear window operation below for details on how these windows operate.
