Hi, my car has the same problem, the n/s/r door is stuck and after walking in the door after work today, I found out the other door wont close. I work with a guy who was at a renault dealership for some time. I'll inquire, as I am in the trade I hope to find a solution. Personally, I cant see how to do it. The door trim card comes of, and I've tried opening the lock from there, but no joy.
I'll inform you if I find out .
