Hi James, if the 3rd brake light is still working it could be the turn signal switch. Power for the outboard brake lights goes through the turn signal switch but the 3rd brake light is wired directly to the brake light switch. Check the brake light switch first to be sure and if that's good, I'd suspect the turn signal switch. HTH. -Jim


Oh, and the brake light switch is at the top of the brake pedal. HTH. -Jim


James, check your fuses under the back seat, driver side. Likely that's all it is. Now if you were playing with putting LED bulbs back there, you 100% blew the fuses. Let me know if you were trying LED bulbs, it's a whole subject in itself with our GMT360 platform.
