If you turn the lights on manually, and no lights, 99% chance it's your HDM relay under the hood. Do you have the quad high/fog modification done, or maybe the previous owner?

No modifications that I can see. They look to be the factory fog lights. I did find both the bulbs blown in the fog lights, so I will be checking fuses and relays tomorrow! Thanks!
