GM Service Manual Online
For 1990-2009 cars only

The power windows are controlled by electrical switches on the door panels and are operated by a motor at each window regulator. Each door has a switch to control its window, and the driver side door has 4 switches to control all door windows on the vehicle. The windows are lowered by pressing the switch and raised by pulling up on the switch. The window will stop movement when the switch is released or when the window is completely open or closed.

The driver side window opens automatically. By pressing and releasing the switch, the driver side window will lower and will stop only when the switch is activated again, or when the window is completely open.

The driver side door control also contains a window lock button that will prevent the operation of the front passenger door or the rear door windows when pressed.
