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+

We have two 2002 firebirds and have replaced all 4 window motors due to motor failure even with little use.
Driver's side power mechanism started to slow down and over a fairly short time it just stopped moving the window at all.

Two replacements of window motor on the passenger side did not fix the problem. I now just live with it.
