Faulty Brake Light Switch...causes this and a myriad of other prblems. Replacing switch no guarantee....I had mine replaced (today, November 20th)...with another faulty switch...creating even more problems (won't shift out of 1st gear...ABS/ESP warnings go on...brake light doesn't work (stuck on "on"). Still waiting for dealer to resolve...have to wait until Monday.
The brake lights work without the key on, so you have a problem with your brake light switch.
check brake fluid
Check BRAKE fluid level. Or is it a "tail lamp" warning? Y-THINK-Y
abs light stays on
=I don't know about the brake lights. I know that most cars, when you turn it off and get out, the head lights and main backlights stays on for a while but then goes off. The brake lights? Maybe it's the way that car is or something is wrong with the brake or you have it on wrong.=
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.
THIS WAS MY QUESTION, BECAUSE THE 3RD BRAKE LIGHT WAS BLINKING I THOUGHT THERE WAS A MAJOR PR0BLEM,TURNS OUT IT WAS THAT BOTH BULBS WERE BAD,CHANGED THEM AND EVERYTHING WAS FINE
The brake light, a red light shaped like a headlight on the dash means that one or more exterior lights are not working. It could be a taillight, brake light, side marker, license plate light, or third brake light. It stays on all the time if it's a side marker or any light besides the brake light. If it's the brake or third brake light it will come on only when you press the brake pedal.
if you mean the brake light on the dash... fill your brake fluid as it's probably low If you mean the brake lights outside the car, your switch is shorted and needs replacement, or you need to lift your foot off the pedal
Any light that stays on is not a "brake light", it's a "tail light". It's possible that they may be on at a lower level normally, and brighten when the brakes are applied, though.
emergency brake light stays on
there is a brake switch under the brake pedal. This is a button that pretty much controls the break lights. you might need to replace this or look through the fuse box under the hood. (blue 15) is the fuse that powers the brake lights.
