Fuse for the "Third" Brake Light
Although 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.

how to change third or center brake light on Chevy beretta 95
Remove the wiring harness from the third brake light. Remove the third brake light retaining screws. The entire unit will need to be replaced. The unit is sealed and the lightbulb cannot be replaced.
My 2002 Tahoe has third row seating.
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.
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.
carefully
Nope.
There are a couple of reasons a 1999 Chevy Silverado third brake light will not work. The first may be that the light bulb is burnt out. If replacing the bulb does not work, there may be loose wires to the connection causing it to not work.
Yes, I have a 2000 Tahoe and it has a removable third row.
the third brake light is direct from brake light switch no fuse
Begin by removing the wiring harness from your third brake light. Remove the third brake light retaining screws. Reverse the process to install your new third brake light.
