Just when we thought the engineers couldn't get more insane with their use of computers to perform simple, common sense functions that don't require those computers, they still did manage to screw up our electrical systems even more. If you added a factory light package designed for your vehicle, the Body Computer and / or Integrated Power Module has to be reprogrammed by the dealer to know those lights are there, otherwise it won't turn on the power for them.

Blowing a fuse removed power from the computer, just like removing the battery cable, and can cause various computers to lock up. The engineers made it so we can have all kinds of problems from simply replacing the battery. That used to be simple, normal maintenance. The place to start is by visiting the dealer to have them connect their scanner to unlock any computers and to program in any new functions.
If you're referring to fog lights, keep in mind a lot of us feel they're rude and obnoxious, and they blind oncoming traffic. If it were up to me, I'd make them illegal except for use in fog.
Holler back with what you find out at the dealer.
