My brother just got a 1993 325is and has a problem with the remote alarm/locks.
When I push the button to lock the doors after exiting, it lights up the dash board, center console, and the rear lights over the license plate. I thought they would go off on their own, but they stayed on and the battery was dead. I charged the battery and tested it out; When exiting the car and closing the door, the lights are off. When I lock the doors the lights come on, but if I use the unlock the doors, the lights go off. This also happens when locking/unlocking with the key in the driver's side door.
How can I lock the doors without draining the battery?
