Circuit/System Description

The rear quarter windows are operated using the rear quarter window switch in the overhead console multifunction switch assembly. The rear quarter window switch is supplied power when the ignition is in RUN or retained accessory power (RAP) is enabled.

When the rear quarter window switch is activated to the Open position, battery positive voltage is applied to the rear quarter window actuators through the power quarter window motor open control circuit. Ground for the actuators is provided by the power quarter window motor close control circuit through the close side of the rear quarter window switch.

When the rear quarter window switch is activated to the Close position, battery positive voltage is applied to the rear quarter window actuators through the power quarter window motor close control circuit. Ground for the actuators is provided by the power quarter window motor open control circuit through the open side of the rear quarter window switch.
