Cruise is fixed apparently.

I was hoping to troubleshoot it myself since its a used truck, but the place I got it from decided to help me out and cover it.

They apparently didnt troubleshoot much and just started replacing parts though...

Replaced the pressure switch, no fix.
Replaced the clock spring, no fix.
Replaced the steering wheel buttons, no fix.
Replaced the servo, FIXED.

They had no probs throwing money at it I guess, but its fixed at no charge to me, so I am happy. Picking it up this evening.

 

Glad the dealer did it, and it was free.
Would have taken me some time to have enough supporting diagnostics to suggest replacing the servo.

 

Got the truck back. Cruise works great. I greatly appreciate your help as well.
