No, there's something in there, after about 8-10 second of the switch being held while the window is stopped there is a click, the current to the motor is cut, a pause, and then another click and is reset itself. If it's just the finger on the switch, why is it only stopping working when the window get fully down against the stop? After it jams, if the stop is loosened so there a little motion in the window again, it rolls right up.
