I have the same problem that is shown in this 25 second youtube video -
The window opens, but when it reaches the bottom, the motor doesn't stop. When closing the window, sometimes it goes all the way up. Sometimes it stops like in the video.
I took the motor out and it seems to function up and down. However, I took a pair of channel locks and grabbed the shaft to simulate window reaching the bottom. The resistance should cause the motor to stop, but it doesn't.
Is there a relay somewhere that is malfunctioning? or is there something inside the motor that's not working correctly? I'd hate to buy a new motor and it not be the problem.
Any help would be greatly appreciated.
