What you can do is take off your door panel locate the wire coupling closest to the door motor (you will see a wire run from the motor to this coupling) and unclip it. You should then see inside the plug that comer off the motor, two prongs. Next apply a 12v positive source to one prong and a 12v negative source to the other prong. It doesn’t matter which because it just affects the way the window goes down. If it cranks but the window doesn’t move stop and switch the connections. If this does not work then your window motor is shot to shit. I have two extra working motors if you want them ill sell you them dirt-cheap.
