    I’ve replaced sensors and jumped wires and I can’t find reason why my low air warning light or buzzer won’t go off. Has a new buzzer and that does work. Is there a way I can wire in new or external out of the dash cluster low air warning light or something?

    thank you

    No warnings at all, even when at 0psi?

    Does the buzzer/light come on when you turn on the ignition first thing before starting the engine?
