Just had to replace the motor on my driver's door recently.

Like motorhead said, check the fuse before proceding.

Then,check the little terminal block (have to have the door panel off to see it) to see if there's any voltage getting to the motor.

If the voltage is there and doing what it's suppose to do when you press the up/down switch, then the motor is most likely bad.

If no voltage is present, then there's likely a wiring problem somewhere.

Bottom line....make sure the motor is even getting power first.
