Do the high-mount brake lites work? Also, you can check for voltage at the stop lamp fuse circuit, use voltage tester, rear fuse block. You have to check with brake pedal applied. If no voltage, check for voltage at the brake lamp switch. Orange wire is hot all the time. When the brake pedal is applied, the white wire goes hot and carries voltage for brake lites.
