Faulty hab door lock

Hello,
We have just noticed that the lower lock on our 2008 Sigma hab door is not working. The bolt has no resistance as if a spring or ratchet has broken within the lock.
Had anyone had this happen on their hab door? We have taken it to our local garage that has carried out various work on the van, and who think that they should be able to repair it. We are also thinking about getting advice from Autosleepers. 
I would be grateful if anyone who has any experience of this happening on their van could offer any words of wisdom.
Many thanks,

Liz

If your door is a Hartal make, then you may have suffered the same as we did: a small (but very sharp) piece of metal about an inch long (a bit like a hook) - which acts as a spring within the door - broke. I found it on the floor although it normally lives inside the door. It's that spring which makes the door-locking lever (there are 2 of them which protrude from the door to engage with the U-shaped lug on the door frame) catch the U lug.

When ours broke, the catch wouldn't retract, and I had to push it in every time after opening the door.
I had to take the van back to Willersey for another issue, and they fixed the door then.

Thanks, Cymro,
It sounds very similar, although I'm not sure which door we have, our van being quite a bit older than yours. I'll give the folk at Willersey a ring tomorrow,  but hoping it can be fixed here in Yorkshire.

Thanks Peter, that's the same as my door, I have saved that to my phone as you never know what you'll need while away, 

Thanks Matt

And if the door is Hartal, it’ll say so on the outside of the door window  at the bottom.
