My rear drivers side light/ lights have gone. I automatically changed the bulbs as the indicator, reverse, fog and brake are all working. This then highlighted that it might be fuse 21. All my fuses look ok and swapped fuse 1 and 21 which cut out the passenger lights. I checked the fusebox and the cables going in and they are ok and I have fiddles with the cables for said problem lights. I removed the quick connect plug to the cluster and that looks ok. Im just scratching my head now so any help is welcome
