Help me figure out with door lock mechanism is faulty please

[Jinster]

I know I have a problem with one of my door lock mechanisms. But I can't figure out which one.

I have a MY97. No remote. No alarm.



When I try to lock from the driver side with 1 turn of the key:
the driver side locks and unlocks
the passenger side does nothing (stays unlocked)


When I try to lock from the driver side with 3 turns:
the driver side locks
the passenger side does nothing (stays unlocked)




When I try to lock from the passenger side with 1 turn:
the passenger side locks
the driver side locks and then unlocks


When I try to lock from the passenger side with 3 turns:
the passenger side locks
the driver side locks



So which side is the fault? (when locking from driver's side, nothing happening to passenger side seems to suggest passenger side problem; but able to lock up the passenger side from the passenger side with the driver's side locking and unlocking seem to suggest driver side problem)




P.S: Both windows courtesy drop when doors are open, so the door-open sensing part is at least ok.

The best guess is that the passenger side is the culprit.
The reason why both lock when locking from the passenger's door with the key three times is that the first time it locks the passenger electronically, the second time it disables the override and the last time it physically locks the passenger door.
Happy Boxstering,

Thanks for the reply, Pedro.

Can I confirm with you that the first turn of the key on the passenger side lock the door "electronically"? I was thinking if the passenger lock is not activated when the key is turn on the driver's side, then it's the electronic lock on the passenger side is the problem.

When I turn the key once on the passenger side, it still locks the passenger side. So that means the electronic lock on the passenger side is ok? I was hoping that with one turn on the passenger side, the lock happens because of the mechanical turning of the key, and not via activating the actuator.

Pedro, you were right.

I opened up the door panel, and found two wires going to DLM sliced in half!

I deduce that the tab that secures the wires to the door frame had come undone and the wires got in the way of the lowering window and got sliced.

Two quick joiners and my DLM works normally now.

AWESOME. Pedro to the rescue again.
