Hello everyone, I have been having the following problem for some time: The rear right door cannot be opened. If you open or close the door, you can clearly hear that the locking mechanism works. Nevertheless, the door does not open. The handle on the outside has no resistance. The handle on the inside has resistance but nevertheless the door does not open. I have already cut off the door and side panels and try to push the lock up in various ways. It is stuck. I am very upset that such problems occur with a Fzg. This class. Has anyone had a similar problem? Is there a simple solution to drive to the Volvo workshop and pay a lot of money? I am grateful for every tip.
