I have a 99 3500 sport 4x4 and I hooped in the truck today, and clicked on the lights and pulled the fog lights on, and went on my way, but when I got to work, I noticed the indicator light wasn't on, so i hoped out and sure enough they weren't on. I checked the fuses, there all fine, and the bulbs are perfect. these only 22,000 miles on the truck, I was just woundering if anyone had any ideas? thanks for the help
