Hi all thanks for all the replies :) I have checked that i am switching them on correctly so thats not a problem. I have checked the buls and checked all fuses in the car, all in the battery compartment, in the engine compartment and under the dash but all are ok. I have no other issues ao thinking that it wouldn't be a relay as i cant find anything that is just for the fog lights themselves. The car hasn't had a tow bar ftted and i checked all connections and cables i can find but nothing... I have no other issues on the control stick but as it doesn't have front fogs its hard to rule out that it isn't this switch that is broken.
