Power WIndow Regulator and motor.

Open the door panel, and test the motor you have after disengaging it from the regulator. If it works, keep it. You can buy just the regulator for less than one with a motor. You can try getting one from a salvage yard, but most places won't piece out doors, they prefer to sell the entire door intact, so you have to find one from a damaged door. Keep calling all the local yards, someone somewhere will have the regulator. Same applied if it's just the motor you need and not the regulator.
