If your brakes lights are not working and all of your other lights are OK try replacing your "brake stop switch". You may have to have either your local auto shop or local dealer replace the switch because it's hard to do yourself. I had the same problem on my Tahoe and replacing the brake stop switch solved it right away.
Yes they indeed have brake lights...
A 2002 Chevy Tahoe uses the standard brake fluid in passenger vehicles with power brakes. It is known as DOT3 brake fluid.
No cruise control or fender mounted brake lights on a 2002 Tahoe could mean a short in the wiring or the ground wire has failed. No cruise control is also a result of a bad oxygen sensor. Most GM made vehicles have two oxygen sensors.
BEHIND THE BRAKE PEDAL
The fuse for the dash lights on a 2002 Chevy Tahoe is in the fuse box in the interior of the vehicle. There is also a fuse for this in the engine compartment on top of the battery. This fuse is for the speedometer and odometer lights.
check the brake light switch
the brake switch at the pedal is stuck or out of adjustment.
If the fuses and bulbs are okay I would blame the signal switch assembly. They call it a multi-function switch these days.
Check the bulbs they are double filamented with smaller being for brake lights
either dimmer switch or blown fuse If you are saying that the tail brake lights are working but the third brake light is not....It may be a defective turn signal switch in the steering column.
I have a 97 Tahoe and the brake lights were not working and the problem was in the emergency flasher switch. I just jiggled it and the brake lights worked so am thinking you might have the same problem. It could also be the brake pedal switch located right on the pedal arm.
Assuming you mean brake lights, the brake light switch is broken or out of adjustment.
Check the bulbs - they are double filamented- smaller for stop and larger for tailights
There is a fuse that runs fog and day lights, check it.
Start with checking the fuses and bulbs. See sources and related links below for bulb information.
check the brake light switch. located on the brake pedal it may be bad
One or more of the tail lights, head lights, or brake lights is out.
Yes, it has brake lights.
The only thing in common with the two circuits you are describing is the brake light switch on the top of the brake pedal. It is also possible that the switch might be adjustable and has moved out of its proper position. From http://en.allexperts.com/q/GM-GMC-781/2002-Chevy-Tahoe-brake.htm
Fuse for the "Third" Brake LightAlthough I have no experience with the Chevy Tahoe, the systems are similar for almost all vehicles.The third brake light is tied into the wiring for the other brake lights and is protected by the SAME fuse they are.Thus, there is no separate fuse for the third brake light.Therefore, IF your other brake lights are working, then a failure of the third brake light to activate IS NOT caused by a fuse, but instead an "open circuit" condition in the "dedicated" third brakelight wiring [from where its wire "splits" off of the wiring harness to the other brake lights].This is usually caused by a connector which has become disconnected, or a cut or broken wire.
To reset the ABS and brake lights on a 2002 Toyota MR2, trying disconnecting the battery for 10 minutes. A Toyota dealer can also reset the lights.
Check the fuses and if they are good then check the brake light switch.
