So I parked it before work and everything worked fine. Hop in the truck after work and my headlights won't come on. All the other lights work and come on just not the headlights. Can't find a fuse for the headlights nor is there a relay box under the hood. Haven't been to find anything online that points me the right way. Also can't find a diagram or description of where the relays are. Please help

 

Check your dimmer switch. All power for the head lights runs to it first then to the head lights.
