Z3 Central Locking Issue

Post by warhammer23 »

Hi there. All of a sudden my driver and passanger locks will not trigger the central locking, but only from the trunk.

I don't use the remote, I just unlock/lock it manually from the key. Z3 2.8 1997.

So:
-Driver side: will only open that door but not trigger the central locking. When I put the ignition, then it will unlock everything else
-Passenger side: as above
-Trunk: fully working, activates all 3 for locking and unlocking.

I heared the wire loom in the trunk is an interest area or fuse 35? Will check later but any other ideas, please do. Thank you.

Question, do you have an anti-theft system from Alpine? That is connected to the doors, but not the trunk. Could be the reason. I would look for jamb switches at the doors, connected to this anti-theft system.
