If it is one of the windows, maybe the travel just needs to be re-calibrated. You do this by pressing and holding the down button, keeping it pressed for a few seconds after it reaches the end of travel stop. Then press and hold the up button, again keeping the button pressed for a few seconds after the window stops.It's like I'm trying to roll up the rear drivers side window when it's already closed. It clicks on to roll up and clicks again to stop almost immediately. I'll try to grab a video next time I'm going somewhere.
