Hi everyone. I recently purchased a 2013 Ducato Motorhome. I noticed that the cable to to the release catch at the bottom of side door was frayed and the lever damaged where cable is connected. The side door failed to open today and I suspect the cable has disconnected from the lever. Does anyone know how I can access the lower locking mechanism to replace the cable & lever as the door cannot be opened. Thanks for any assistance you can provide.
