I have a 2000 540 and am experiencing some annoying electrical problems. It all started when my rear window got something in the way while closing and jammed while the safety pullback went into effect. Now the symptoms are:1. All door windows operate only from their own buttons and will not operate from the drivers master switch. 2. Only the rear door locks operate from the center push button. The front ones do not operate at all. 3. The drivers side mirror adjustment works but not the passenger side.
Now I have tried replacing the GM3 module with no luck and am now thinking that the master switch at the drivers side is fried but am not sure how the locks fit into all of this. Anyone out there experienced similar problems or may have some ideas as to where I need to be looking?? Thanks for any input!
The thing about the central locking system is when one component fails or stops working the whole system goes wonky. The auto close window feature can be reset. I would start with that. Try the reset procedure a few times, as some people have said it doesnt always work on the first try for what ever reason. Please not the procedure (contained in link below) needs to be done with the door closed. It will not work with it opened.
Other issues with the door locks could be the door actuator itself. They contain a small microswitch that can fail over time.
