Circuit/System Description

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

The power window system will operate any time the ignition is the ACC or RUN position. The power window system will also operate whenever the body control module (BCM) is in RAP mode. The master power window switch contains individual window switches for each power window. All windows may be controlled up and down from the master power window switch. The individual rear passenger power window switches will only control the up and down operation of their respective power window.

Each power window contains a reversible power window motor. The direction the window travels is dependent upon the polarity of the supply voltage. By reversing polarity of the supply voltage the window motor will move up or down. Each power window motor is internally circuit breaker protected.

The drivers window switch has an express-down feature that is labeled AUTO. This allows the driver's window to open fully without having to continuously press the switch. Press the switch to the second position and the driver's window will go all the way down. To stop the window from lowering, lift the switch all the way up and release it.
