Go back to 4 wheel parts and get them to fix what they screwed up. I suspect they did not use relays. Also, putting more powerful bulbs in the factory fog lights is known to make the computer freak out because you are drawing too much current. The JK makes extensive use of the CANBUS system. If you want a more powerful bulb in your factory fog lights, the way to go is to with a relay. I really don't fault the dealer, because a modification was made to your electrical system that caused a malfunction. 4 Wheel Parts should take care of the problem if you bring it to them.
