Passenger Window Operation

WARNING: This page is about a different car, the 2002 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

When the ignition switch is in the RUN position, the lockout switch is disengaged-up and the individual window switch is pressed to the down position, voltage is applied to the window motor down control circuit causing that window to open. When the individual window switch is pressed to the up position, voltage is applied to the window motor up control circuit and that window closes. The return path to ground is supplied through the inactive control circuit being normally grounded through the driver window switch. Operation is the same from the driver window switch, except that the lockout switch position is ignored.
