WARNING: This page is about a different car, the 2006 Pontiac Montana SV6, 2006 Chevrolet Uplander, and 2006 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
When the ignition switch is in the RUN position and the front passenger window switch is pressed in the down position, voltage is applied to the window motor causing that window to open. When the front passenger window switch is pressed in the up position, voltage is applied to the window motor in the opposite direction causing that window to close.
