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.
either your fuse is blown or the wiring is bad
Check the brake light switch.
Check the fuse, check the bulbs and check the brake light switch, it should be one of those.
The 2001 Chevy Blazer brake lights may not work and the third bake stays on because the current light needs to be replaced. A replacement brake light can be purchased at an Auto Parts store like Pep Boys.
Yes they indeed have brake lights...
The center high mount led brake light unit has been known to go bad.
Just a suggestion, check your trailer lights harness for corrosion. They were taking the dash lights down in my chevy.
I can't turn the yellow brake or parking lights on my 1998 Chevy blazer off and it's draining my battery.Could you please tell me which fuse or switch I'd use to disable the front yellow lights? This is happening even with the car off.
brake light switch is bad
On a 1998 Chevy Blazer, the parking brake switch is located on the top of the parking brake assembly. There are 3 bolts that hold the switch to the parking brake assembly.
Brake Lights Stay on Unless the Brake Pedal is RaisedThis is usually caused by the brake light switch being out of adjustment in its physical distance to the contact point on the brake pedal arm.
Directly above the brake pedal.
