I have a 1998 2500 diesel. I would like to know what dark knight did to repair his. My problem is similar to leadhead. Intermitent. As long as the truck is cold, the cruise works. When it's warm, it doesn't engage & won't until the next day. Went on a long trip & was only able to use it for a short period each day. This weekend it was fine. Go figure. Leads me to believe it's electronic. Either a hidden relay or the CCM.
