I have same year Tahoe and same problem. Check fuses first to make sure it isn't a fuse. The third brake light assembly can be removed by opening the back door and unscrewing the screws. Then unplug the connector. A new unit is about $175.00 and the whole unit must be replacee as it is LED light not bulbs.
Yes they indeed have brake lights...
How do you replace a break light switch on 1995 Chevy Tahoe
BEHIND THE BRAKE PEDAL
about 3 dollars
3rd brake light or rear brake lights?
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.
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.
The brake light switch is bad, look on top of the brake pedal under the dash and you will see the switch, replace it and you will have brake lights.
Start with checking the fuses and bulbs. See sources and related links below for bulb information.
A diagram to replace the brake light on a 1999 Tahoe can be purchased from your local auto parts store. It is located in the Haynes 1999 Tahoe Repair Manual.
When you open your tailgate...are there 2 screws near the tail-light? homshopper at yahoo dot com.
On the junction panel on the firewall just above and left of the brake pedal. You can see it quite easily, pulls out. Replace with exact part or lights flash at the wrong rate.
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.
its probably not a fuse at all, but it could be your brake light switch. its under the dash hooked to the pedal. I had to replace one on my 84 t-bird
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.
Need to know what the question is.
A 2002 Chevy Tahoe uses the standard brake fluid in passenger vehicles with power brakes. It is known as DOT3 brake fluid.
You may need to check your brake light switch. It is a small switch located on top of your brake peddle (up on the arm of the peddle). This switch allows the brake lights to come on whenever you push the peddle.
If the brake lights do not work on Chevy Venture van 2000, try to disconnect the brake switch. Then short the two contacts of the connector to check if the brake lights are now working.
How do you replace brake lights
on the brake pedal under the dash is a brake light switch. that when you depress the brake it turns your lights on. you might wanna check that
Depending on the repair shop you can look at around 200-300 dollars.
the connection between the battery and the brake lights
You need to CHECK the brake light FUSE with a test light. If the fuse is okay then check the brake light switch. That is just above the steering column under the dash. It is H..L to get to.
use an ohmmeter it will show the ground or a test light if it lights up it willl be the other wire
