Also consider an open ground wire. The clue is to measure the voltages on one of the motor's two wires. You'll find 0 volts on both of them until you press the switch, then you should find 12 volts on only one of them. If you find 12 volts on both of them, the most common suspect is a broken or frayed wire between the door hinges.
