i have a 1996 chevy s10 ext cab. and i just wired up some trailer lights to it because im jus gunna run those til i figure out what kinda tails i want..but the brake doesnt work..the turn signals and running lights both work..and the brake should run through the same wire as the turn signals..so i am thinking its my relay..but i cant seem to find them..i looked at my fuses and its not blown..so im convinced its the relay..any body who know where they are located?or what else you think the problem would be?
You could try looking in the back of the glove box. I have a 97 dime and i had to switch one out for my headlights, not sure if the brake lights are in there too, but its worth a try. good luck
