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.

Mark your answer was perfect. I had two brake lights out and knew the odds of it being the bulbs were slim. Read this post, replaced fuse 34, and got both brake lights working again as well as Cruise Control back.
