i cant open one of the back doors,the mechanism is working ?

what EVER is attached to door panel needs to be removed will be held by screws ,clips etc some will be hidden inside handles etc when the panel has been stripped insert a screwdriver around the edge looking for the press in clips gentle lever off .to find the door will be covered with a plastic sheet, tease this back where ever you want to inspect and check linkages, when happy put it all back
