You need to check the wiring that travels from the fuse box to the lights to make sure that it has not been cut or broken somewhere. Also check the wires that are directly hooked into the light. Mine had become corroded by rust once and broke the circuit. We cleaned them up, hooked it back and they worked.
Good Luck.
There are brake lights in 2 places - the taillight housings and the center/high-mount.See "Related Questions" below for more about removing the covers and accessing the bulbs for both locations.
Put this question into google, and you will find many reasons and remedies to this problem. Ei...brake light switch, brake light bulbs, including the upper brake light bulbs.
check the switch at the break peddle
The 1999 Mercury Sable license plate light and the right side brake light are on the same fuse. If the fuse was bad neither brake light would work. The problem probably is burnt out lightbulbs.
Check bulbs Check Fuse Check stop light switch
on some cars the tail lights and brake lights are totally different bulbs gain access to the bulbs and have someone push the brakes so that you can determine which bulbs are the brake lights and replace the tail lights
AnswerThe brake light switch will probably need replacing. This is normally located on the arm of the brake pedal. Looks like a push button switchSee "Related Questions" below for more
AnswerThe bulbs for the brake lights are usually separate from the normal tail light bulbs. Check and replace the brake bulbs first, and if they are still not working examine the fuses, switch and wiring.
its on different bulbs
fuse, bulbs
you do not adjust the brake lights check the bulbs or check switch top of brake pedal.
The brake lights and tail lights are separate wiring systems. Even some of the bulbs may have two separate bulbs in the same glass housing. If the bulbs are in fact working, then the next step would be to test the brake switch under the dash. When you depress the brake pedal the switch is pushed creating a connection to turn on the brake lights.
