No Jake or cruise, no switch stuck?

With this info now, Im now leaning towards your brake pedal switch being the issue, dont remember on petes where that is, more familiar with older kw setups, but try to either lift up on the brake pedal or see if the brake switch is misaligned

 

so your cruise control isn't working at all correct? Your Jake's work fine but basically come on all the time?

If this is the case I'd look at your brake switch. I think, could be completely wrong, it's behind the kick panel behind the pedals. There's a couple air switches back there. low air and such.
Google it

 

I had a issue like this 2× b7t a little different 1st was no cruise but Jake's worked 2nd was cruise WOULDN'T DISENGAGE with the pedal..

Both times it was a corroded pin (different pin each time) on the plug going into the ecm... also did it a 3rd time when the accelerator pedal stopped working
