A door window may move slowly or stop in mid travel due to a failing power window motor. The affected window may start working again after the motor cools off. Replacing the faulty window motor will commonly correct this concern.Google+

This was accompanied by the window failing to slide up correctly into place, leaving a gap in the rear border.I chalked the failure up to other drivers in my family trying to force the window up after it reached its incorrect stop.

just installed brand new regulators in both doors last month because the passenger side stopped working. they worked great, but now my driver side window stopped about 2 inches from closed. I waited until the morning to let it "cool" down but to no avail. guess its time to pull it all apart again and put in some more.
