My brake lights are not getting power to the back.Other lights are.94 Chevy Cheyenne
Start with the brake fuse in the fuse box. It is labeled Brake And there is another fuse labeled Stop. Make sure these are good and have power to them. More than likely it is the brake switch located on the brake pedal assembly. wiggle the switch assembly while pushing the pedal down with your hand. See if that makes the lights come on.
