Lost Cruise Control

I'm not sure if this is still the case, but if the fuse for the brake lights blows, as an indicator, the cruise and/or the dash lights quit as well.

Check other items to see if they function.

As mentioned , Could be a few things. Below link offers one possible cause.

Maybe the cutoff switch when the brake pedal is pushed.

Cruise has been built into the engine computer for a long time. No separate fuse.

Had this happen to me on a Ford E350 RV that I owned. Turned out to be a loose connection in the wire harness under the dash that contained the cruise control wires.

Try pressing all the cruise control buttons at the same time.
When my Jeep sometimes loses the cc start function, it seems to engage it, if I press the CC on, Set, Resume, and Cancel buttons at the same time.
