Circuit/System Description

When the ignition switch is in the RUN or ACCY position, or retained accessory power (RAP) is enabled and the driver window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing the window to open. When the driver window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction and the window closes. The driver window switch also controls the passenger windows.

When the ignition switch is in the RUN or ACCY position, or RAP is enabled and the lockout switch is disengaged, battery positive voltage will be available at the passenger window switches. When an individual window switch is pressed in the down position, battery positive voltage is applied to the window regulator motor causing that window to open. When the individual window switch is pressed in the up position, voltage is applied to the window regulator motor in the opposite direction causing that window to close. The return path to ground is supplied through the inactive control circuit being normally grounded through the driver window switch.

The driver window also has an express-down feature. This switch is labeled AUTO. Press the front of the switch part way, and the driver window will open a small amount. If the front of the switch is pressed all the way down and released, the window will go all the way down automatically.

To stop the window while it is lowering, pull the front of the switch momentarily. To raise the window, pull and hold the front of the switch.
