Hello bigtone welcome to the site your problem might be a bad earth going to your front fogs ,maybe trace the wires and see if there OK, check bulbs are ok , check fog switch is ok,or try getting power from another point to see if they work it's just getting some means of process of elimination I guess ,As for the fans well maybe try power from another point ,sorry can help more than this but will you let us know how you get on perhaps other members will help you more than I could.
