I'm not certain, but you may have a problem with your car's "wiring harness" that's inside your door. As O'lRattler said, I believe it's in the accordion section of the door. Mine went to crap on me on a trip away from home. I couldn't open my fuel door or open any of the windows from the driver's side switches (I could open them from their individual switches, however). Also, my MFD showed my driver's door ajar--it wasn't (the "door open" chime kept chiming because of this--about made me nuts!) and the interior lights wouldn't go off. Supposedly, several wires had broken or were damaged at the harness--and I've never messed with anything in the door. It wasn't under warranty (78K miles), so it cost me about $440 at a dealer in Cary, NC.
