Dumb fog light question

[alex_and_sean]

I changed out my fog/driving lights and now they don't come on and the light on the switch in the cab doesn't come on either. Thought I might have a bad relay and swapped what I think is the right one but no dice. Could the switch have gone bad? What else should I check? Can't imagine what I did in the simple swap out but they don't work anymore. Feel like a total dolt too! :wall:

Fog lamps only work when the headlights are on low beam. Headlights on high beam or off, fog lights don't work.
