Question about 1988 Chevrolet C1500
My brake lights are not working. The tail lights work but when ever I step on the brakes the brake light doesn't come on.
First ensure the bulbs are fine.
Check and replace the fuse in your fuse box.
If it keeps blowing after replacing the brake lights fuse, then there is a short on the wires, you need to check wiring.
If fuse is ok and there is no brake light check wiring to the lights, there is a broken connection or an open wiring to the brake lights.
Note: brake lights are usually not dependent from tail lights, they have separate wiring.

the break light wire on the lumina runs through the blinker switch or multifunction switch on the colum.. check there as well as at the tail light sockets. on the late 90s gm cars the sockets had a tendancy to rot away... use a test light at the brake light wire in the trunk and have a friend apply the break. if there is power then may have to get new tail lights. or replacement bulbs.

Testimonial: "THANKS FOR THE HELP"
SOURCE: tail lights dont work
Replace the bulbs.
The bulbs will have two seperate elements in it which is why the brake light works.
Take the bulbs out and you will see the seperate elements.

are the bulbs good. do these use the same bulbs for brake/turn signals?. if the high mount light was working, then the brake light switch was good. brake light power goes through the turn signal switch. you will need to get a wiring diagram and verify the power is going in and coming out of turn signal switch.
