Just replaced a driver side power window motor assembly with an after market motor and track. Not sure if I can name drop on this sight but it is a reputable company that I've used many times. The problem is, everything matches up and wires up correctly but the motor will only go so far up and there's still about a three inch gap. I marked the track and took the window out thinking maybe the window was in a bind and that was causing it to stop short but the motor won't allow the arm to travel the required distance and nothing is in a bind.. Any ideas or thoughts? Thanks!!
