My truck has no brake lights but does have turn signals, hazards, and running lights, we have ruled out brake switch on brake pedal and brake light bulbs
have the same problem?

If you are sure it's not the brake switch or bulbs check for ground at rear and at trailer connection where it is wired in if you have one. Then check t/s switch fto see if it's getting power through that
