    ok guys/gals, my dad has a 94 silverado! brake lights aren't working, tail lights work, signals work, just no brake lights! on the right side signal, when head lights r on, the right signal blinks like double time! we have changed the brake light switch, nothing happened, checked with the volt meter thingy on his old 1, & it was good according to the volt meter, pretty sure he has checked the bulbs! is there a ground problem, wiring harness connection, anything, any kind of help would be nice! thanks, carl!

    yep, we have checked all the fuses, sorry forgot to mention that! the fuse box, that has a fuse spot, for brake, doesnt have a clip or anything to even hold a fuse in it, so i dunno if that was ment to be like that, or, maybe the truck never had brake lights!

    I had this issue with my old 95 Z28. I sold the car before I took the time to figure it out. It wasn't fuses and I couldn't find a ground issue. But then again we're talking about taillights and I didn't go over the entire harness looking for issues. I would say that's what you need to do... and boy does that suck. I always start with the exhaust manifolds/headers though. 3 separate times I've had issues with wires being burned there.

    I have the same problem with a 1999 2500 4x4 Suburban. Someone told me in another post that it is the connector plate behind the tail light lens - it's a black chunk of plastic with an internal circuit board that the bulb sockets are mounted to. I am buying some replacements today - hope they work!

    its your boards that the bulbs are mounted in, pull them out of the laillights and look at all the connectors where the bulbs pop into they are gonna be slighlty scorched, they are pretty cheap to replace as they are a common problem, most good junk yards carry these that are brand new

    something else you might also think about or check is if there was any trailer lighting hook up added after the truck was bought some back woods people like to just twist the wires together and then wrap electrical tape on the connection after to protect the connection. I personally use butt connectors and heat shrink so that any connections i make stay made. after only a short while the electrical tape starts to turn gooey and then unravels and you have shorts in the system and that could just as easily be the problem since both would involve the lights at the rear of the truck. if nothing else might be something else to check.
