Need to fix rear fog light for MOT and I can't find fault.Replaced switch on dash (power at switch), checked bulb,checked wiring,checked fuse in left hand side in engine compartment and still nothing!! The only thing I think it could be is (not sure if I've got this right,no manual!) the fog lamp relay on the right hand side in the engine compartment? Would this be right as I need to know the correct name for the part before I start looking for one?? Have tried google but so far have not found one!Car is an Almera Action 1.4 1998 N15.Any help much appreciated.
