driver's window
From GM:
Window Indexing
This feature automatically lowers the window a small amount when the door is opened. When the door is closed, the window will raise to its full up position. If either window does not index properly, it could be due to loss of power. Before returning to your dealer/retailer for service, perform the power window initialize procedure.
Power Window Initialize
After a power reconnect such as battery replacement, the window index-up feature will not function until the system is initialized.
Once power is restored:
1. Close the door.
2. Raise the window and hold the switch up for three seconds after the window is closed.
3. Release the switch, then hold the switch up again for three seconds and release.
