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+

POWER WINDOW SLOW UP SLOW DOWN HAD TO REPAIR DRIVER WINDOW NOW NEED TO REPAIR PASSENGER WINDOW,
Driver's side power mechanism started to slow down and over a fairly short time it just stopped moving the window at all.
Drivers side will not roll down. And passenger side rolls up and down slowly. Have to roll it 2 - 3 times before it will close all the way. Had someone replace switches which didn't work,

Motor went out. Replaced the window motor. The new one went out less than a year later. Now it will work every few months for a few days and then quit working again.
