I have wired the rear lights of my camper conversion into the Van's existing wiring loom. All was fine until about 2 weeks ago now, all the lights stopped coming on. I did have a wire fall off the new door switch this has been resolved and reset. What I seem to have now is, the lights dont come on with the fob but when I put the key in the ignition they do, that didn't always happen. When I get out and lock up they go out, I unlocked it again straight away nothing. Its driving me mad just cant find the fault. Please help
