Individual Window Operation
WARNING: This page is about a different car, the 2004 Pontiac Aztek and 2004 Buick Rendezvous. However, it is still accessible from the selected car via links, so may be relevant.
When the ignition switch is in the RUN or ACCY position, or RAP is enabled and an individual window switch is activated to the DOWN position, battery positive voltage is applied to the window motor causing that window to open. When the individual window switch is activated to the UP position, battery positive voltage is applied to the window motor in the opposite direction causing that window to close.
