Did a search - nothing matches my problem. I turn on the lights and hit the fog switch and the 15 amp fuse pops. I replace the fuse with a 30 amp and do the same thing - lights go dim but the fog lights do NOT come on - left them on for 4 or 5 seconds and cut it off for fear of burning things up with that 30 amp fuse - Do I need a new headlamp switch? Fog lamps have worked recently but I did a lot of work to the car - including a 3g 200 amp alternator upgrade with disconnecting the 2 10 guage wires and running just a battery cable from the alternator to the battery (charges GREAT)
