    At that age, it could be numerous things. Being able to monitor functions with software would point you in the exact direction.

    Any cruise problems I’ve had are caused by, clutch safety switch, Either one of the two actual switches themselves, the speed sensor on trans, or the air application switch on the parking brake. In that order.
