Knowledgeable Ford person question?
On my heater control the temp control blows hot even when you turn it to cool on the temp control. The truck is a 2000 F-250 Superduty. I did not see a control device on the heater hose, so I as...

Can you change from vent to floor to defrost? Your system is all vacuum controlled.
Blend door is not vacuum operated..
It is an electric SERVO MOTOR.
If you notice item #4 does not have a vacuum line routed to it.
I'm wondering if it would be a good idea to add a water shut off valve to the heater core?
Sounds like a pain to replace the servo motor.
It switches from floor-vent- defrost without issue.
The A/C worked fine last time I used it before this problem.
Like I said earlier it seems to be working again, I can get cool air out of the vent again.
I think there is a lot of very knowledgeable people on this forum and again I would like to say thank you.
I would also like to take this opportunity to especially thank Gdetrailer for his insights. He's been here a long time and often offers valuable tech info. He may seem a bit blunt at times, and I don't always agree with him, but I highly respect his tech savvy and enjoy reading his posts. In this case, between #40Fan's link, and Gdetrailer's talent for detail, I learned quite a bit about my own year 2000 Ford trucks. Three cheers for these guys, and a tip o' the hat for others that contributed too.
And good luck to you, colliehauler, on going on to solve the problem permanently. It sounds like a good idea to me, to add a water shut off valve to the heater core. Less hassle than tearing the truck apart and you shouldn't have to reset the valve often, more-or-less seasonally only.
As an aside, even the truck forums are dead wrong on occasion. I had a steering problem with my "pre-owned" F-250, and the only guy on the whole net to ever solve it was immediately dissed by the rest of the forum members and never posted again. It turns out the previously installed new ball-joints were too tight and most local alignment shops across the country had no idea, had never heard of it. Most operators would be first inclined to think the steering was somehow too loose, but it was exactly the opposite problem upon close inspection, and is not uncommon on Dodge 4x4 either. Coming from constant steering correction, it steers like new now, no fancy aftermarket suspension gimmics needed.
