So I just purchased a certified pre-owned 2017 GMC Sierra Denali 1500 from a dealership. After getting home I noticed that my fog lights were not turning on when activated along with all my headlights. It shows in the dash that it's on and I checked the fuses in the engine compartment to be good. Bulbs are installed and hooked up. Not sure where to go from now. Any help would be greatly appreciated.
