Hi, I have been having strange electrical problems since I put my 3 Door away for winter. Hazards/indicators not working, heater fan intermittent and rad fan not working. Rad is getting hot all round, tried 2 new switches in the rad now, fans work if given a direct 12V feed. If I short out the wire to the rad fans nothing, but if I put 12V to one side of the fuse they come on. Also found a couple of blown fuses. So how hard it is to take out a 3 door fuse box, and can they be replaced? Phoned local Ford dealer and they inform me there is no flasher relay on my car, can’t believe this somehow!

Thanks for any advice
