Have Ford Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.
Are you saying if you set the cruise to 30 mph for example and come to a hill and the speed drops to 25 mph or less the cruise shuts off?
If that is the case then that is normal, cruise is not meant to work at low speeds and is cutting off.
Now if your saying it works for 25 miles then it cuts off and will not come back on that is something different. If this is the case do you have to turn the engine off or press off then on then set again? This is not a fuse or relay issue, more likely related to a PCM or clock spring issue.
