Intermittent Cruise Control Function

[250_SD_Beast]

I have a 2008 F250 - Job 1 with intermittent cruise control function. Occasionally when I turn on cruise and hit set, it does not come on no matter how many times I push on and set (at or above 30 - 35 mph). Much of the time I can shut my truck down and restart and cruise will work, but not always. Once it is working - I can turn off cruise and restart it and it always works. If I turn my truck off there is a chance the cruise will not start. Anyone have a similar problem?

I see it frequently. I use cruise every day to and from work and see it at least once every 2 weeks.

Took my truck in yesterday - turned out to be the brake pressure switch. Cruise thought that the brakes were applied so it would not engage. Took a few hours total to troubleshoot and fix. Seems to work as it should now.

I had the same problem. Replaced the pressure switch and it worked for a few hours, then it started again. It turned out that the wire harness connecting the pressure switch was "stressed" to the point that one of the wires got torn inside the insulation and stopped making contact. The pressure switch circuit (when open) reports "pressure on", hence, the cruise control will not come on.

I fixed the harness and all's well since.

Can you guys steer me in the direction of this harness? My truck has just recently started doing this as well....

Thanks.
