89 325i sedan Central locking stopped working one day. Both front doors lock and unlock with the key, but central locking does not work.
However, it works no problem from the trunk.
So I figured my central locking control unit might be bad and ordered a brand new one from BMW, and also cut the wires going into the door, as the RTS Auto article recommended.
However, no change. Things are the same. Key unlocks both front doors independently, but the trunk can central lock. What should I try next?
