The wiring in the turn signal switch seems to be a weak point on these trucks. My wiring insulation was rubbed through, and all of the trucks in the scrap yard had wiring that was even worse than mine. Several had aftermarket clamp on turn signal mechanisms.

 

You can still get new turn signal switch assemblies that are a direct fit to what you have now, no need to modify or adapt.

If all the fuses are ok, the dash light(s) failure are most likely the dash light dimmer that is built into the headlight switch.
