Have you checked to see if your back lights are not burned out? That could be the problem.

If your bulbs are good then you have a broken set of wires going to the rear lights, (look by where the trailer wiring was installed if so equipped as that's a common area of problem for broken wires. Hope that helps. i had the same problem with my 1985 south wind it had a exposed wire that ran right behind the brake peddle throw the floor Bord they did make the hole big enough so when the pushed the wire throw it striped it so every time i hit the brakes the fuse would blow. and i would have no lights. don't know if this helps you, good luck .

It is not necessarily the fuse. It could be the switch on the brake that is not closing the circuit.

Why don't your brake lights work on your Chevy s-10?

You may have blown a fuse. You may have to replace your brake light switch which is located above the brake pedal under the dash. Also it could be your emergency flasher knob if its broken. All of your turn signals and break lights run through it and if the connections on it are off none of the brake lights and turn signals will work.

A defective brake light switch could cause the problem. Also a defective turn signal switch could also. The brake lights work through the turn signals. It cancels the brake light so that the turn signal can work.
