Chevy K20 Tail Light Issues Solved 

Similar issue. 1988 chevy r30, 2wd, 454, tbi, 400 trans, dana rear... no brake lights lol. Got running lights, tail lights, no brake lights... nice vid. Short n sweet. Helps me start looking around, thanks man

Thanks this was helpful. Tail light & turn signal would work, but no brake light. I checked everything from fuse, bulbs, socket, ground & nothing until i seen your vid👍🏼 turned out to be the wires that go to this switch.

Having the same problem in my 1984 c20, thanks for this very helpful!

Thx a lot , this helped a lot!!!

thanks that helped i have a 85 k 20 and not sure why but out of know where and i replaced the flasher but still don’t work and the lights are fine any ideas?

running lights work off the brake switch as well? I've built this truck out I suck at wiring though it eludes me lol

Just checked my 84 Chevy Blazer 4x4 switch and it's not working. Now I need to order that part.

My 76 c10 is a factory Air cruise truck. Seems to be the vents for blowing on the floor are in the way of viewing the switch. Looks like I get to start taking stuff apart. Never that easy is It. 😂

Are tail lights and brake lights the same 🤔

I think this is my issue. I replaced all my wires and tail lights. The Blinkers work and tail lights turn on when I turn on the headlights but brake lights don't work

Thanks 💯💯💯💯

That was helpful

I got a 78 and it has 2 of those switches what could the other one be for ?

So my issue is that when i push the brake paddle, the driver side shuts off and the passenger side works fine

those are brake lights not taillights duh!!
