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+

not sure why but when I put the window down on drivers side sometimes it will not go back up..if I wait a few minutes it will go up some more until I get it up..Its frustrating. I just had that motor replaced about 2 years ago.
