    Yesterday I lost Engine brake on my truck during the day and then All other controls on STEERING WHEEL by end of the day.
    Here is the list in Order as I lost them:
    Eng brake
    MMarker int
    City horn
    Headlight int
    Air horn
    Cruise control
    Radio controls

    I am hoping its a simple fix like a wire harness/ broken ground. Any help will be appreciated.

    Gonna look at ESC tomorrow for Corrosion.

    I had issues with dump susp too but thats since last month. 20221208_182141.jpg

    This is the first time I’m hearing something like this happening. I was curious to know if you fixed the issues you were having & how did you do it?

    Take the horn pad off and check the main connector didn't come apart. Clock spring under the steering wheel is a possibility, next easiest connector is right under the steering wheel where the harness plugs into the bottom of the clock spring.
