My truck was done a couple of weeks ago. Huge difference. More air volume for heat and A/C and the air is much colder .
More volume would be a big plus for me.

Is this affecting new trucks....2021's?

Doh, my bad. I'm on Tapatalk and it cuts some of the title off. Just trying to edjumicate myself.No.
It was for 19-20 trucks built before 8-1-20.
(hint, read the thread title)
What’s the procedure for checking the vents?
I know we’re looking for consistent temps across the dash vents, but are we looking for a certain temp drop below ambient?
Last summer I felt like my a/c was not as good as I wanted it to be, but I was coming from a king ranch so I didn’t really think too much about it.
Interesting video showing the discrepancies with the air temps. It seems like an easy fix installing the valve, but (me) not knowing anything about the flow of coolant thru the vehicle system, does closing that valve off have a detrimental effect on the entire system flow?
I agree. This is a design defect that is fixed by replacing the HVAC ducts and control module. There is no need for the dealership to do any troubleshooting on a truck that is covered by the TSB. The TSB even states, " DIAGNOSIS:If one truck is bad and they have to change out the entire HVAC box, that means that ALL are bad. I guess that I need to find out if the dealer will do the TSB without symptoms. I checked mine today, but I think I need to get it up to temp to see if the problem is there. We have had the truck since May of 2019 and because of Covid, it only has 2100 miles on it.
How reputable is the dealer you went to? I wonder if they just topped off the freon and said yeah we put in the 8 hours labor to do your free tsb.I finally got mine back after getting the TSB done on Friday. Honestly it was only 85° Out so it’s hard to tell the difference. I threw some thermometers on it just to see it was getting maybe 55° air which i don't think is much different than when I had before but time will tell when Arizona hits 110. I don’t really notice much difference in the blower speed which is interesting. But what the hell I figure worst-case I’ll just clamp the heater core again.

Temps are consistent across all the vents now at least. I don’t remember weird temps on max heat. But looking back at my notes 55 is about 10 degrees cooler than what i got during summer on max AC previously. My dealer is a good dealer and i can tell they did something....What is the temperature differential between the driver's right vent and the passenger's left vent? 55 seems high.
Also, were you experiencing the problem with the HVAC blowing weird temperatures when not set on max heat or max cooling? Mine (and @g00fy) both had problems with the temperature fluctuations, but I am no longer experiencing that problem.
