Apparently this is the point when the fuse for that circuit blew. So, I turn on the hazards, hoping I don't get rear-ended by some moron while I have no brake lights. The radio was still pulsing with the hazards, soon blew that fuse as well...

Luckily got to work without an accident and quickly found the short in the obvious place- the brown wire in the rear taillight harness from some POs shabby hack job. Fixed her up with a butt splice and some heat-shrink and replaced the burnt out fuses(Tail Stop and Traffic)

Now I have a more complicated problem:

What does work:
-Blinkers
-Hazards
-Headlights

What does not work:
-Brake Lights
-Parking lights
-Instrument Cluster Lights

When testing the fuse panel, with the key on, all fuse circuits are hot on both sides except 'PNL. LTS.' This circuit is dead on both sides.

When testing the headlight switch, the red main feed is hot in all positions as well as the orange wire. The only effect the switch seems to have on any other wires is the lt. blue headlight wire which is hot with the switch all the way out.

I thought this may have been the problem, but swapped it out with a known good switch from my other truck with the same effects.

So, looking for some advice as to where to look next. I was thinking it could be the turn signal switch, as this will cause the brake light problems, but can't figure out why it would cause the parking/dash lights to go out.

The truck is no longer popping fuses. I assume this means I have an open somewhere.

Any suggestions? -Chris
