Driver Window Operation
WARNING: This page is about a different car, the 2003 Pontiac Aztek and 2003 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 retained accessory power (RAP) is enabled and the window master switch is activated to the DOWN position, battery positive voltage is applied to the window motor causing the window to open. When the window master switch is activated to the UP position, battery positive voltage is applied to the window motor in the opposite direction and the window closes.
The window master switch also controls the front passenger, LR, and RR windows.
