I have a 1965 C10. I completely rewired the truck using an AAW classic update kit. Up until 2 weeks ago all the lights worked on the truck...no problems. Then, recently, everything works, HL, blinkers, and tail lights except the passenger side brake light. The drivers side works fine...but no brake lights on the passenger side. The tails and blinker work on the PS...just not the brakes.
I checked connections for corrosion, but don't see anything obvious. I do have LED's with an LED flasher and they all work fine. I am stumped where to even look at this point...so I need some help please.
