Question about 2003 GMC Yukon
Chances are the problem is the turn signal switch.
Someone would need to check the circuits going in and out.
The third brake light passes by the switch, the rest go thru it.

did u check that they not burn?if not you should Check the wires going into the steering column if you don't have separate turn signal lights and brake lights because if they use the same bulb then the turn signal may be bad. If I remember correctly that particular car doesn't work this way, but I include it just in case.

I had the same problem with my 1999 Yukon. The electric board needed to be replaced. Rust starts to build up and shorts out or blows the bulb. The dealership charged $73.60 for the part and I installed it myself (Saved $30).

Disconnect electrical connector to brake switch brake located near brake pedal. Check for twelve volts or power with a test light on one side. If power, get a piece of wire, strip the ends and plug into each end of connector. If brake lights works, switch is bad. If not, check bulbs and power in the brake light socket. If no power, check to make sure power is leaving the trafficator switch as the brake light switch is depress or bypass. Check for broken or bad connection along circuit. If all good, you could have a trafficator switch problem. Oh, are the hazard and trafficators working in the rear? If they are, the trafficator switch is bad because the brake switch sends power there, then out to the back through the left and right rear trafficator wires.

It sounds like the brake switch, that is usually located along the shaft of the brake peddle under the dash, these sometimes are in a bracket for ajustment may not be able to depress switch. Falow starting at peddle go up to dash, you should be able to see it. Hope this helps.
