My brake lights are not working. I have checked the bulbs and the fuses what should I do I can't afford to have it worked on? 2002 chevy blazer

Check your brake switch that is located under the dash and is activated when you push in the brake pedal.

If the other brake and turn lights are working the brake light and flasher units are ok . With a test light check at the bulb holder terminal and bulb holder body, test light should glow ,if not check from terminal to a metal part of panel away from the light body . If test light now glows the brake light body has a bad earth if the test still not glowing the power cable to the light is broken.

Do you have power in and out of the brake light switch ?

first check to see if the brake lights are working. If they are you will need to pull the center counsel and repair the broken wires fro the shift interlock.

If the brake lights are not working. check the fuse and the switch. The switch will be under the drivers side of the dash mounted on a bracket near the brake pedal lever. The fuse will be in one of the fuse blocks and labeled BRAKE or STOP.

did you check the VEH STOP fuse? #34, 15 amps, in the rear fuse block, under the left rear seat.

Check your wires, the smoke could mean an electrical fire.

Trace the wiring as it comes from the laft and right brake light. May have to remove the brake light covers. Sounds like a crimped or shorted wire leading to the brake lights, possibly a loose or broken ground wire. One of the wires leading from the fuse block to the rear oif the vehicle could also have been damaged if the door sills have been removed by someone earlier to install things like speaker wires, etc. Also check to see if you have tail lights and directional signals.

When you replaced the bulbs did you get bulbs with double filiments - one acts as the tail lights, the other serves as the brake lights (both inside the same bulb). Compare the ID numbers on the bulbs with those which are required for this vehicle, but you should clearly see two different filiments inside of the bulbs when viewed from the side.

I had a similar problem and when i went to the auto electric place the guy said its a brake switch next to the brake pedal which is not working. He took it out and fixed it. Now its all fine.

It is a common chevy problem for the circuit board that holds to bulb to fail, are your running lights and signals still working back there as well? If not then you need to replace the boards.

When my blazer did this they had to replace part of the wiring harness in the steering wheel. It took forever for them to get the parts because we live in nowhereville, but once it was in it works again and no problems. I had to take it to the actual chevy dealer because none of the other places had a clue. good luck.
