My Front Passenger side door lock in my '91 535i is stuck in the unlocked position. When you unlock the rest of the doors, you can see the front passenger side door lock move a little but it does not lock. I was thinking that something inside the door has jammed up or that maybe that the lock motor was bad. Has anyone had experience with the door locks. How much of a pain is it to remove the door panel? HELP, I want to lock my car!!!
