my chevy express 3500 brake lights will come on randomly when the truck is shut off and parked. Sometimes at night the dog will start barking and I’ll look out and see the lights on. I have to go out and disconnect the battery to shut them off. Could this be a short somewhere or the multifunction switch in the steering column? Please help
Check the brake light switch adjustment that is mounted near the brake pedal.
It sounds like you have a smart and on guard dog.
