I have an 05 E350 and for about the last four years my cruise will quit working, maybe for a short time, maybe longer. Example, going to Orlando a couple of years ago my cruise wasn't working....after six hours on the road and hitting the on and off switch and then the set switch quite often it started working again. Have had it in shops that never could find anything wrong with it. After it started working again it was a year and a half before it quit again....same sequence for getting it going again except not as long on the on, off, set method. Had bought a new replacement switch but hey, when it works it works.
