Headlights are now not working
 

So at first everything worked perfectly; marker lights, fog lights, and headlamps all good. Then the fogs came on with the marker lights and head lights and stayed on. The fog switch did nothing. Now the fog lights are on with the marker lights, the fog switch does nothing, and the headlamps won't come on! Headlamp switch and or relay? Fog light switch? I did learn that the fogs illuminate the road quite well under 45 MPH!!:)

Usually people start by inspecting/cleaning grounds.
