Chasing down an electrical problem.

[Beefcake]

I have a new problem with my ¾ ton. I suspect it has something to do with my hazard circuitry. When I pull the hazard tab, nothing changes, I don’t get the blinking lights.

What is constant is the lights and gauges are all going crazy. My turn signals lights always say lit, The fuel gauge gets pinned down to empty when the brake peddle is applied.

Im not sure how the hazards work. But since they aren’t working at all, Id like to fix that first. What makes the hazards blink? Where is the box located? What does it look like? Im really hoping its something as simple as the (hazard box) malfunctioning.

thanks!
