New to me 2002 Volvo V70 XC. The passanger side door will not unlock with the key fob or with the door lock buttons inside the car. It will appear to try to move, but does not lock or unlock. It can be manually locked and unlocked.

What parts are inside the door that could be causing this? Is there a chance that something jumped track or slipped out or needs adjustment? I would rather have an idea before I take the door cover off in case I have to order parts.

Thanks!
