The power window system consists of the following components:

When the ignition switch is in the RUN position and the driver window switch is pressed to the down position, voltage is applied to the window motor down control circuit causing the driver window to open. When the driver window switch is pressed to the up position, voltage is applied to the window motor up control circuit and the driver window closes. The return path to ground is supplied through the inactive control circuit being normally grounded through the driver window switch.

The driver window switch also controls the passenger windows. Refer to passenger window switch operation below for details on how these windows operate.

The driver window will travel to the fully down position if the driver window switch is momentarily pressed down past the first detent. Press the driver window switch to the up position in order to stop the window.

The driver window switch has a lockout switch which, when engaged, disconnects the power supply to the passenger window switches, preventing the passenger windows from operating from the individual window switches. Passenger windows can then only be operated from the driver window switch.

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.
