Brake buzzer and dummy light Light goes off when I release brake but buzzer keeps going Also level Jack's not working Thanks ahead of time 93 pace arrow with 8.1 Cummins and Allison 6sp.
I got Jack's to work by taking park brake off ( backwards from how supposed to work) Still buzzer going off... I also pulled hazard lights and it turns the brake booster under driver's seat on & off & on & off...
