Hey I found you a link, this may help:

Can we all agree that on auto mode, the Truck should change the temperature and Blower speed to Whatever it needs to to get the set temperature.

On manual mode, it should only blow the temperature set and only the blower speed that is selected.

In my case, in manual mode, I can have the temp set anywhere between high and 61 and it blows max heat. It only Starts to blow cool if I set at 60, it does not blow cold until I set at max cold temperature.

exact same way my HVAC operates. I agree with auto. In manual mode , decreasing the temperature from HI to any other selection (except LO) is comes out of the vents at the hottest temperature.

In above post I mentioned DEFROST and AUTO at the same time because I know it’s an impossible selection.
It was only to feed thought into a normal situation where you need cool ambient temperature to defrost the windshield but again, it only comes out piping hot

If it never stops blowing uber-hot air that's a crazy issue - faulty temp sensors or some such thing. That's an absolute problem as even on manual mode you have a temperature set and it should get and stay there and not go above.

Maybe these are supposed to be different and never blow air warmer than your setting, but some of my other vehicles, they did - until they got the cabin up to temp. Then the air cooled down and it mixed the air to maintain the temp.

Good one chief. You really socked it to me with that one.

To blow Uber hot air to cool things down is not a normal operation. Let us know how your system is operating

Anytime, hope it helps.

Defrost does come out quite hot. Good thing, too, as it takes that much heat to melt the freezing rain off the windshield and the frost off the inside of the glass on other days. Don't want cool air up there, dry air yeah.
When I choose defrost, the fan kicks to high, the temp jumps, the ice melts, then I turn off defrost and it goes back to normal.

So, if the cabin temp is say 65 and there's hot air coming out and you are roasting and you set the temp down, it doesn't comply - it's as if a mixing door isn't moving. Ford had a similar issue a while back with certain pickups - but that was a failure of some mixing door motor after a while. That's almost what this sounds like - it's not controlling that door in there.

And dang, he was FAST with it, too!

I agree sounds like the air isn’t getting mixed properly. But wouldnt that affect auto mode also ?

Shadow, please. Next time you drive your truck , select any vent you like the air to plow. Start on the highest and hottest setting. When it is very hot and uncomfortable, decrease temp to 65 degrees. Can you time how long it takes for 65 degree air to blow out of the vents?
Remember.. in manual mode

My viper technician said the same thing. The blend door. If he weren’t 60 miles away I’d have the car in his hands by now. Hopefully after the new year I can make it up to her dealership he works at.

So evidentially I’m a quick reading Chief? Thanks guys

Now you are definitely out of my realm. Give me a tech service manual.......... and a couple of hours. LOL - seriously, I did HVAC among my work but these are so computer now........... you would think that it would, but this isn't like the thermostatic control of a few years ago.

Now all this has me wanting to investigate with my own JT and see if I can hear the doors moving, and in what modes. That used to a a clue - change certain things and either listen for or watch for things to happen.

I can only compare to what my Chevy did in auto mode - that thing was smart. My wife would get in and change things around. I'd stop her and ask - what temp do you want it in here? I'd set it to that temp, hit auto and when she tried to argue - trust me, this truck is smarter than either of is - it's programmed to know the best way to get to your temp and not freeze you out in the process - you could predict when things would happen by watching the engine temp gauge. It was like some computer program was running it all. In manual mode it was like you set a thermostat and you got totally different results. You either roasted or froze until it got to temp.

Ah for the simple days when I could pull a heater core out in under an hour, two tops on the tougher ones.

(we'll see how much I stick to that when I go to put AC in my Jav next year)

I get too distracted reading. That's my issue - the ADHD means if a word down further catches my eye - suddenly I miss a sentence and have to go back. So I prefer pictures and numbers.
So I salute your speed and evenness on things.

If that's the case, and the more I think about it, the more I lean that way........... either the door or the controls, and if I'm correct they are electric motors now...... then there could indeed be a bigger issue - something sticking, not assembled right, faulty connection or motor, etc.

If it was an older vehicle, I would say check for mouse nest........ insulation blocking a door.

We all want the same result, I just happen to be, due to DNA, extremely detail oriented, systematic and need all of the relevant background information, then work through a solution.
