I have a 88 325i, and my left rear door, Drivers side will not open. From the outside, you can not open it, nor from the inside of the car. I feel something might be jammed, the litle knob that pops up when u unclock the doors, doesnt pop up. The trunk will unlock every other door, except this one.. From the inside, it looks like the handle is sort of half out, but it wont move, its like stuck like that, might be jammed im thinking. Well what do I need here, and can someone please tell me my prob? Thanks again.
