Hi new here. I have a Mk3 Clio diesel. My reverse lights and reverse sensors don’t work. Changed the reverse position switch on the gearbox but that hasn’t solved the issue. The new switch works but still no reverse lights. The fuse F20 in the engine bay box is fine too. Just wondering if anyone has any ideas what else I can try or any more fuses/relays and locations? Didn’t really care before but now that reverse lights are part of the MOT it need to get done. Thanks!
