No lights working, main or side lights when switched on been to Halfords have checked bulbs and say they arent blown. Have checked fuses they arent blown either. When the light are switched to on the windscreen wipers dont work, and the air conditioning doesnt work when the lights are switched to off the windscreen wipers work. Halfords say could be the electrics. Have also checked the fuses but they havent blowen either. Does anyone know if this would be expensive to fix. Has anyone had similar problems with a Fiat Brava?

u have a bad earth problem.

looks like you will have to go to an auto electrician they might have seen this problem before thats all l can suggest.

just have a look behind the fuse box perhaps some wires came out there
