I had the same problem while on a 14 hour road trip from nc to Michigan, worked on it in the parking lot for 3 hours. Replaced resistor, fuses, relays, jumped power to the the motor and it worked fine. Turned out to be a loose connection. There's a white harness above the interior light above the passenger kick panel pushed it tight and worked like a charm. I must have knocked it loose when I replaced the bulb in the light.
