    Rained on day and then the cruise quit working, the jakes were sputtering like if your sliding on ice how they keep cutting out, and you can't idle it up.

    Peterbilt tried spraying it down and couldn't find the problem, issue still exists when dry out so I brought it back and they changed the clutch switch and said it's fixed.

    My driver says it's still buggered, said the jakes seem to be working fine now but no cruise or idle.

    While driving the dash screen would keep flickering from the time to saying the cruise enguaged speed if that helps.

    Spending a bit of money here for what would a pear to be a very expensive truck wash so far so your help would be appreciated. Cat c15 if that matters.

    Its a short

    I had that happen to me
    Couldn't fast idle
    No cruise
    No Jake
    No dash lights

    Sounds like a short somewhere in the dash.

    Also knocks out the anti idle software in the truck to ;)


    There's a good chance the truck got struck by lightning and that's what caused it.
