Check the obvious first such as bulbs, connecting plugs above spare tire, brake switch above brake pedal to make sure it didn't come loose. If everything looks normal, start by checking ground wire by tail lights, check all fuses in fuse box. If fuses are ok, start checking for voltage at tail lights and work your way back following an electrical schematic. Usually it's a loose or corroded connection or a plug that came loose. Good luck
