Our left rear window has not worked for awhile and I thought is was the motor in the door. Then I discovered that if the driver's door and the left rear door are open - sometimes the window will work. Other times it won't. Also, we have wiggled the rubber "conduit" that wires run through on both doors and this sometimes lets the window work. From anyone's experience, is this a typical wiring problem or I am missing some other test or clue? thanks for any help that you can give!
