Can confirm this solution. I had the same issue. Removed cover from bottom of steering column, unplugged the harness connection going towards the light switch on column, cleaned up the top left pin (yellow wire with blue stripe, which was burnt) and plugged it back in.Thanks to all. The problem was in the wiring harness to the headlight switch on the steering column. The wire was yellow with a blue strip. it showed as burnt. took it apart, clean it, put some dielectric on it, crimp it so it would be tight on the switch terminal. The fog lights also started working when I fixed the connection. I guess it is wired in somehow thru the lighting sys.
