I have stock factory fog lights on my 91 XJ, and just today they won't turn on anymore. I have the lights set to running lights, not off or brights. I checked the fuse, its not blown... and I noticed that the little light on the fog light swtich in the dash also does not light up when switched to on either. I took a voltometer to the wires on the fog lights (I'm in the middle of installing aftermarkets) and there is no voltage coming to them. Everything else on the jeep is fine, anyone have any ideas?
