    2007 T600. Cummins ISX.
    Yesterday suddenly when leaving shipper, cruise control will not engage. I have replaced the air switch behind dash, the clutch switch. Haven’t replaced the on/off switch yet. I can still bump the idle up or down. Just no cruise set/resume, or hit resume for high idle. Any ideas??
    Frustrated!

    Hmmm..? Well, I just changed out the on/off cruise switch. That didn’t change anything. So, the brake light switch is what cuts it off when touching brake pedal??
