Why won't the exterior brake lights go off on my 2001 Chevy Blazer?

Behind and above the brake pedal is a pushbutton switch. When the pedal is not being pushed, the steel part of the pedal arm hold it in, essentially shutting off the brake lights. When you push the pedal the switch is released, turning on the lights. It is very easy to see if you look under the dash. I'm not 100% sure if "won't go off" means they don't turn on, or don't turn off. If they won't turn off, it will drain your battery because that circuit is live even when the ignition is off. Possible causes of your problem are: 1. The switch is misaligned. That would make them stay on all the time. If that's the case, you can turn the lights off by pressing the button directly to see if that's the problem. 2. Switch is disconnected or faulty. Easy to tell with a continuity tester. 3. Blown fuse.
