try replacing the brake light switch; it is located under the dash directly behind where the brake pedal is. it should actually have a small button that is released when the pedal is depressed. You can check the switch on the bench to insure this is the culprit, simply place an ohm meter across the two contacts; you should have no continuity when the button is depressed, as soon as the button is released you should have zero resistance.
Other possibilities could be a blown fuse on the brake light circuit, or a blown bulb.
brake lights dont work
Check the fuse, the bulbs, and the brake light switch.
Check the brake light fuse. If you have 12 volts at the brake light switch I would suspect the signal light switch is at fault.
Above the brake pedal. If your main brake lights dont work but your third center brake light does, then the brake light switch is not the problem. Its is the turn signal switch.
Check the brake light fuse first. Then check for a bad brake light switch at the brake pedal.
change the brake lights check the fuse check the brake light swtch
The fuse may have blown. Be sure the bulbs are good.
it could be that your brake light switch under your dash that sits right on top of your brake pedal has gone out
Check the fuse, check the bulbs, check the brake light switch, in that order.
Check the: Bulbs Fuse Stop light switch
Warning light usually indicates low brake fluid or parking brake not fully released
Yes check all of those, if not any of those you might have a broken wire.
