Hi all, I have a very unique issue and no one has figured it out yet. When I switch my hazard lights on my ignition comes on. It overrides the ignition which stops the key from switching the engine off if it’s running. Two years ago I changed the flasher relay and the Hazard switch so I assumed the problem is elsewhere but having spend all day on it checking connections, earths, fuses, wires Im going to guess it’s the hazard switch again. It has Lucas on the back but can’t remember buying an expensive one 🤔. Any ideas?
