Well if it's a power window it's most likely a bad motor/ regulator but quite possibly a switch.Remove the door panel it all looks good unplug the motor and manually supply power and ground to the two terminals if the motor moves you have a switch/ wiring problem,if not,you have a bad motor.Polarity does not matter when you supply power.One way will go up reverse them and it will go down
