I must start by saying I'm very green at trouble shooting wiring issues. So here is the problem. Headlights worked a week ago, out now. Taillights, parking lights etc all work. High and Low beams both out. Checked fuses and changed the one I thought was associated with headlights (upper right in fuse box?) Tough to read labelling. Fuse looked bad. No change in light function. What should I do/check next? Never had headlight issues before. Will say that last time I was driving(Sunday) car my foot caught part of wiring under dash above gas pedal( I know secure wires) and stereo (not factory stereo) cut out and back in. Is there a ground under the dash that would impact headlights? Can't be certain this was the cause as it was daylight out. Headlights did not work when went to put the car back in the garage that evening.
