I looked at some of your other posts and see you recently purchased the truck used.
I suspect this is the first time you tried the cruise?
There were some truck fires due to defective cruise control design.
It affected millions of Fords and there just weren't enough replacement harnesses to go around.
Ford was concerned about fire and requested that all vehicles within the recall (ijncluding yours) come in and have the CC disconnected.
They would then notify the owner when the part was available.
This time lag could run 6 or 8 months.
By then some drivers were used to living without the cruise or for whatever reason said screw it.
I suspect that over the years we'll see this same thread topic over and over again and this reason for failure should be added to our toolbelt of knowledge.
