Hi,
Did you just recently get the vehicle? The fog lights should operate when the headlamp switch is pulled outward. You should feel a click. If you just purchased the truck, there is a chance parts were changed as well, and the new (used) body parts may have had fog lights and your vehicle didn't originally have them. If you look under the vehicle where the fog lights are located, is there an electrical connector plugged into the light?
I ask if you just got the vehicle because I'm questioning if someone has replaced the headlamp switch with the wrong type (non-fog light vehicle).
I ran through the wiring schematics for W/ fog lights and DRL and without DRL. Both schematics indicate the fog lamp switch is in the head lamp switch.
Let me know. Sorry for the crazy questions but I suspect you may have just got the truck.
Let me know.
Take care,
Joe
