Headlights and running lights are not working?

Sure, it can be a couple of different problems but let's start with the easy stuff, please check fuse # 25 7.5 amp and fuse #56. Here is a guide to help and the fuse locations in the image below. If the fuses are okay, I would try swapping out the taillight relay. Here are the wiring diagrams for the switch as well so we can test through it.
