Hello all. My e34 suddenly developed locking problems, the driver and passenger doors and the trunk lock and unlock without fail from their respective keyholes. The passenger keyhole only locks and unlocks the passenger door and the trunk, and the driver keyhole only locks and unlocks the driver door and the trunk, the trunk only unlocks and locks itself as usual. I manually pressed the little levers to make the two rear doors lock since I cant lock them any other way and would rather them be stuck locked then unlocked. I checked the fuses, and unless a fuse is missing, the fuses are fine.
Possible suspects:
Maybe a relay?
Maybe the general module (windows dont go up, only down, and windshield wipers dont work). My brother messed with the battery and fried the DME and ASC, so this could very well be the problem.
Maybe something in the driver/passenger door that tells the other doors to lock as well?
Thanks for any help.
Yes, I would look at the GM as well since that controls the central locking and windows. However the windshield wipers run on a different relay, it is next to the headlamp relay box on the driver side under the hood. It is located in the fuse box, and you should see two or three VHS cassette size boxes. Those are the headlight, and wiper relay boxes.

Thanks, when I was typing it out it sort of became clearer to me. Where do you think I should buy one? I looked on ebay but I dont really trust that an ebay one will work. Is there anyone on the forum that sells this kind of stuff?

Found my culprit! Left side of the trunk hinge. Don't know who did this previous hack job but I soldered, mended them all back together, and my central locks are back in order.
