No Brake Lights, please help! - Diesel Place : Chevrolet and GMC Diesel Truck Forums

I have a 2004 2500HD Crew Cab 4wd (lly). I installed new LED tail lights yesterday and the brake lights did not function. I checked every fuse that I thought would be related to the tail lights and found one that was blown under the hood. I replaced the 10 amp fuse and the tails/turns/park lights worked perfectly. Today, I find that the parking lights work, both left and right turns work, but no stop lights. No more blown fuses. I also noticed that my 3rd brake light is no longer lighting upon hitting the brakes. After testing for current at the tail lights with my test light, I am not getting any current. What should I check for? Could it be the brake pedal switch? I'm at a loss here
