There may already be threads on this, but i'm new to the site and still figuring everything out.

I have a 2004 5.4 Lariat. The cruise will only work after the truck has been sitting for long periods of time, like overnight. The colder it is, the longer it will work. Normally, I can set it for a minute or 2 when I leave the house and then it will stop working until I've left it sit overnight again. I've had it looked at twice and no one can seem to figure out what it is...not pulling codes, switches test ok, etc.
Anybody else had this annoying problem? thanks in advance
