Check the brake light switch.
Just a suggestion, check your trailer lights harness for corrosion. They were taking the dash lights down in my chevy.
either your fuse is blown or the wiring is bad
check the multi function switch. I hava a 96 Chevy Monte Carlo and I had the same problem . I changed the multi function switch and the brakes lights now work. the rear brake lights run thru the switch on the turn signal circuit. try it and see.
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.
The center high mount led brake light unit has been known to go bad.
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.
Yes they indeed have brake lights...
brake light switch, it is typically located above the brake pedal somewhere on the brake pedal arm
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.
Ensure relays and parking brake switch are properly functioning.
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.
