My driver side window does not want to go up or down so right now i have the window taped up because its pretty cold up here in wisconsin. i replaced the master power window switch because the rear passenger side window wouldnt work unless i used the switch at the door so that fixed that but the driver side window is still screwed. when i push up or down i can hear the motor working so i was wondering if this could be a bad regulator or what? any suggestions would be great thanks
