Help! - door lock problem

[chenderson1965]

We have a 2012 3.0L Arto 79L.

Today our hab door lock has stopped working. The lower lock mechanism won’t open to accept the bar that’s on the frame.

I’ve taken off the inner cover and, as far as I can see, everything is working correctly mechanically, and the solenoid motors seem to engage and operate ok.

The ‘c’ shaped piece of metal that grabs the bar seems to be over rotated so that it’s either in the ‘lock’ position (2nd pic), or in an even more closed position (first pic). I think it should move between the ‘open’ position and ‘lock’ position.

I can’t see anything blocking it’s motion, or any way to remove and check it (the pivot seems to be riveted in position).

We can just about get the door secured by forcing it to engage the top catch, but it’s obviouslu]y not ideal.

Has this happened to anyone else?

Does anyone have any ideas/suggestions?

I don't know if this will help but the problem seems similar to a problem I had with a Berlingo tailgate lock about 10 years ago. It would unlock OK but would only lock if the car was on a slope. It turned out that a small spring, which opened the ‘c’ shaped piece of metal fully had broken. I actually fixed it with a rubber band temporarily.

Thanks, but it’s not a return spring issue.

It won’t even return to the open position with some fairly heavy persuasion from a screwdriver. Something definitely seems to be blocking it but I can’t see an obstruction or a way to dismantle the mechanism to examine it more carefully.
