Sounds like the dealer is lying.

Like I said, it is very possible if FCA has put the parts on restriction.
But the TSB says that all that is needed is for the customer to make the complaint,
it says nothing about restrictions on parts being released.
It does not have to. Any manufacturer, when faced with a parts shortage and they have to make a decision between installing a part on new trucks vs releasing it for a TSB, they will pick the new trucks every time. They won't short their "money makers" and slow the lines down for a TSB on trucks already sold.
Safety recalls can be a different story, but this is not that, its a technical service bulletin (TSB).

Got the TSB for the AC performed on my truck last week. They put on the RO that the customer states AC on left side is not as cold as the right side or something to that affect. Anyways, got it replaced. It does seem colder and I believe it has made a pretty big difference. I have not measured the vent temperature myself. Seems like there is a slight smell of grease coming out of the vents. Maybe thats the new parts?

Got the TSB for the AC performed on my truck today. I had complained about the AC a few times before but they just checked it, added some refrigerant, and sent me on my way. This time when I dropped it off I also dropped a copy of the TSB which was provided in this thread. Thanks for that! AC doesn't seem to blow quite as hard as it did before but definitely cooler. We will see how it does in the hot Florida sun!

Well, I had my truck in a week ago again for AC, also failed O2 sensor (second time). Dealership ordered parts ref the AC TSB (24-001-20) and O2 sensor. Parts in today. I have an appointment on Tuesday for install: Shall report back. Temps in central TX here get to 110 some time, so ne better working will be appreciated. Sometimes, the vent temps on my truck vary by 12 degrees, and I haver to run truck hard for over an hour to get temps below 50 degrees, central vent in town stays at 57. So shall report back.

2020 limited here..... Living in Georgia the truck did fine. Now I live in Arizona... And I sweat with Max AC on and ceramic tint on every window and windshield. Very annoying. It's fine when moving but sitting still it's not good at all.

OK, since U in TX, U understand. Last year, I did the AC hack with the clamp, and was able to get my Drivers vent down to 44 degrees, it was like Xmas in July. SO shall see after done and will post.

Totally!
It’s only mid June and already in the upper nineties. At least it has been sorta low humidity in Houston these last few days.

So it's been pretty warm here in FL since my AC repair was done. Central vents measured a low of 49 on a 95 degree day. Previously measurements were in upper 50s and I would never take my AC off of full blast. Now I find myself dropping the AC back which is a good sign! Hopefully you get a similar result!

Glad to hear!
I used Tempe Ram. Sam Battaglia was my Service Advisor and was very helpful.

I hope so. Well turned in truck this AM. Truck not be ready till tomorrow. My central vent temps in town were 57 degrees, so ne thing in the 40's be great. I can still do the AC hack if I need it colder. I have the hose and the valve just in case and a clamp for temporary.

Hopefully you don't have to go the clamp route after the repair. It made my AC much better and should do the same for you.

WELL, here is my take on that: I have a "Ball Valve", proper size, and hose and clamps. IF this fix does not work, I will put a "Ball" valve in the Return line from the water pump to the heater core and stop it this way. With the clamp on this line, my temps went from 57 degrees to 42 degrees in town. The only bad thing is: Fully engaged, U have no warm air ref window fog and such. TRUCK still there from yesterday, hopefully done today. Truckers with Big Diesel rigs been doing this forever. Would be a shame to put $30.00 of parts on a hose line in a 50K truck.
ADDED: Been doing some reading on the 2021 Chevy's with the new "Duramax" 3.0L Diesel: Many have been blowing engines with less that 5,000 on odometer. I sure hope that is not a pattern, regardless of wat U drive, sounds like the ED's, though they lasted longer than 5K, LOL. WHY I got rid of my Gen 2 ED. I had ZERO issues, just did not want to be in the line of not if but when, LOL.
