these are very common for multi function switch / hazard switch assembly failures that can cause this issue as we know the brake switch is good if you have the center brake light working

if the bulbs are good and the fuses are good see if the white wire into the multi function switch shows 12 volts when you step on the brakes the odds are it will and then replacing the multi function switch should correct this problem you are having

I have removed dash, wiring harness; checked all wiring and found no problem. Third brake light works when white wiring is energized. No brake lights.
