What is causing my window to come down way to fast. It was working properly then it stopped working. I took the panel off and could hear a click coming from the motor. I took the motor and window assembly out and after reinstalling it the window is not working properly. It goes down so fast it is uncontrollable. Will hit hard on the bottom and the gears jam and I have to start to take the motor out before it starts to go up and down again. What did I do wrong? I gave up after working on it for over 6 hours got real tired of taking the motor out and trying to get it back in the tracks.
