Hi, I'm a new member and Need help. I finally figured out how to join the family of Hummer owners.. Is great that we can help one another.
My wife's hummer H2 2004 front driver window only moves down.. i disassembled the door panel and applied direct power to the motor and got the window to move up and down by reversing the polarity. Can someone tell me if the problem is most likely the control module switch. I don't want to spend $160 if unsure. All the other buttons work fine. Also, the window does not close when i press the button that opens and closes all windows at the same time..
Thanks
