Central locking acting funny
Hello.
Recently I had a problem with the rear left lock:
when I drive off, the doors normally lock. Now, only 3 of them lock and one is not locking.
When I use the console button to lock the doors, 3 doors lock and 1 does not.
When I use key to lock the doors, all 4 lock.
When I use key to unlock the doors, only 3 unlock.
If the rear door is locked, and I try to unlock using a button, it does not unlock.
So, this pattern indicates that the door will lock with the double locking but will not respond to any other lock/unlock commands.
Is this something with the lock hardware, cabling/pins/bolts?
Or is it something electrical, like blown fuse or a relay?
Or the "lock brain" has gone south?
Any ideas?
Thank you,
