Tail light problems! Please help!

[Graham Cole]

Hey guys! So my 96 chev k1500 just got back from paint and now it's wanting to fight with me. I'm getting no rear lights whatsoever, but my third brake lights work, does anyone know what the issue could be? Everything worked fine before it left here for paint and now that it's back its not working. The box was off the truck if that helps anyone, thanks guys!

I'd start checking grounds and pinched wires

Yes or it could be a simple as a disconnected plug. Trace the wires back and you should find the problem. I would start at the tail lights, and work my way back to the cab.

As far as I can tell there's nothing unplugged, but where do the grounds go on these for the rear? Where would I look for a bad ground connection?

 

[Graham Cole]

I wanna say a ground or maybe a bad plug because it's got nothing back there, no brake, tails, or reverse lights

The easy way to figure this out would be with a test light. Find where you have power, and where it stops. As for the ground, The frame is a grate ground, so you could always jump a wire off from the frame for a new ground source.

If I'm not mistakes the wiring that comes from the front runs down the inside driver side frame rail. I've had problems with the area right above the axle

Okay so from what I could get around here before my fingers got cold, my plugs are corroded up and now after further investigation, the hazards work and the turn signals work but they hyper flash, would it be the circuit boards inside my taillight showing bad just from sitting?

 

[Graham Cole]

I tried another taillight I had kicking around and it still did the same

The hyperflash comes from a light being out somewhere. It could be the circuit boards
