How do I take apart my rear door of my 1998 BMW

Ignition key works the manual door lock:
You get out the original fob... pull out the (metal) key... insert it into the single lock slot under the drivers side door handle...
and twist like an old fashion key lock.

If ur radio is bad maybe your antener has come lose at rear of head unit... some systems also earth through the antener so this could cause it to shut off. Hope this helps.. Craig

dead battery

an air lock in the system.that is what the bleeders for...

remove the handles and door panels you will find the track strip the raises the glass up and down to be broken or stripped ! that can be replaced from a salvage or order one new!

I am not familiar with this car, but most with electric locks can be unlocked the old fashioned way by placing the key in the lock and turning. Barring that, call for a wrecker or locksmith to open the car, or somehow get power to the electrical system to power the locks. If the hood is open, or openable from the outside, just use jumper cables to apply power. Perhaps you could get to the starter feed cable (or even the batter feed) from underneath the car. I hope this gives you some idea that is helpful in resolving your problem.

look for screws on the handle inside or under the arm rest next pop a corner of the panel away its normaly held on with door clips they are a little hard to pop off you might break a few but local dealer should have more most likely some will break if the window wont go up you probaly have a bad motor or window regulator if window goes up slow then stops its more than likely a motor possibility of having a bad window switch

replace the window control switch it is defective.

I had the same problem on the rear door of my 1998 528i and it was the door actuator that had gone bad. I had to take the rear seat out to get the door panel off. Once I had the door panel off it was not that difficult to replace the door actuator.

replace relays and fuses for the power seat and windows.change dash light bulbs.if bulbs are good you got wiring problem check ground wires.
