I own a 200 BMW 323i wagon and I have a diagram on the inside of the fuse panel door.
You will find the engine number on the 85 BMW 323i on the driver's side of the engine block. Using a flashlight will help you see it better.

FIND THE SHORT TO FIX, IT'S PROBABLY IN THE HARNESS IN THE DOOR JAM.
About the only way I know is to find one in a wrecking yard.
it is located at the very left corner of the instrment panel, right of the hazard flasher and in front of the door chime. Also, if the Hazard Flasher is still working, you can engage it and find the area they are in by the sound. (Clicking)
Removing door panels from cars is pretty easy. A person needs to find and unscrew all of the screw holding the door panel in place.
Find your fusebox and see if you can find the fuse for the auto door lock mechanism. Just pull the fuse out and it should take care of the problem.
