Question about 2002 Chevrolet Avalanche
Fuses and relays and bulbs look good. High beam works parking lights work and fog lights work
My guess is the turn signal/multifunction switch. All your light go thru here. except the third brake light. Here's is some electrical schematics, hope this helps

Sounds like its a problem with the light switch handle. Had it myself as well...
If you're savvy enough around car electronics take out the light switch handle, take it apart, find the problem and fix it. Inside the handle-switch you have several slide-switches and some double action slide switches.
Otherwise - get a different switch from a local junkyard or get a new one from your dealer.
