Tell me about it. I think its the refrigerant used and the compressor.Hello everyon,
I’m still waiting for my TRX to arrive as a replacement for my 19 Rebel, I loved everything about my Rebel fine truck i took it everywhere & done everything with it my only downside was the AC performance i had to do the AC hack and only then it became acceptable, I live in a hot country and the AC is a dealbreaker, Appreciate all your input thanks.
The TSB fixed this. I have a 2019 also.Tell me about it. I think its the refrigerant used and the compressor.
Wow, so it's a simple as flashing the ECU ?The TSB fixed this. I have a 2019 also.
Cheers,
It's a little more involved than that...Wow, so it's a simple as flashing the ECU ?
I have a unlocked one from Diablo hope it doesn't hinder the process.
My 2020 Big Horn is plenty cold. 98 degrees here in Minnesota! I think people just like to complain on here. People complain about squeaks & rattles, this & that. How about being grateful u have a car & don't have to walk 10 miles every morning for fresh water ?!
Well good for you for having a truck that blows cold and has no rattles.My 2020 Big Horn is plenty cold. 98 degrees here in Minnesota! I think people just like to complain on here.

Well 52c in Kuwait sure feels like Arizona mid July, but man 40s here feels like a tropical area, which somewhat helps the A/C cool faster.I live in Kuwait the hottest country on earth today was 124F almost 52C without a proper & well functioning AC I can’t even drive a car so AC performance is the first thing i ask about when buying a new car, My 19 Ram Rebel had a real AC performance issue that Ram Officially addressed! The only one complaining here without reason is you!

Parts are in back order from dealer, everyone complaining on how poor the A/C functions during summer.
Traded in my '19 Longhorn and didn't bother to switch out the KCRay hack back to OEM, and I even told the dealership I traded it in to that it's now their problem to either go back to the crappy air, keep the hack or do the fix, lol. Just ordered a '22 TRX and I am confident my air will blow a lot cooler than the old truck.I understand how people keep complaining about AC in summer specially in our region thats not unusual, But my 19 Rebel had a real issue my 16 Rebel was so cool even in July so far same goes with my 21 TRX.
Jtr my Rebel was a fine reliable truck took it to the desert, mountain, beach and daily drove it to work my only issue was the AC and KCRay hack saved me during tough summer, Congratulations on your 22 TRX I’m sure you’ll be satisfied i love the AC on my TRX and thank god no issues so far.Traded in my '19 Longhorn and didn't bother to switch out the KCRay hack back to OEM, and I even told the dealership I traded it in to that it's now their problem to either go back to the crappy air, keep the hack or do the fix, lol.

I just figured out that freon is a registered trademark and not the scientific name of the refrigerant.I believe that the freon was changed from 134a in 2020 to 1234yf in 2021 which would require a complete AC redesign.
USA law requires elimination of R134a in new cars by 2021, Proposed rules will also affect Medium/Heavy Duty vehicles (includes Medium Duty trucks, 250-350or 2500-3500 pick-ups, and Heavy-Duty vans).
The automotive air-conditioning industry changeover to low global warming R-1234yf involves a lot more than new fittings and a more robust evaporator to prevent leakage of the mildly-flammable refrigerant.
An initial group of new A/C-related SAE standards was developed. link
What was the “AC hack”?Hello everyon,
I’m still waiting for my TRX to arrive as a replacement for my 19 Rebel, I loved everything about my Rebel fine truck i took it everywhere & done everything with it my only downside was the AC performance i had to do the AC hack and only then it became acceptable, I live in a hot country and the AC is a dealbreaker, Appreciate all your input thanks.
KCRay AC hack just search ‘KCRay‘What was the “AC hack”?
Awesome, thank youKCRay AC hack just search ‘KCRay‘
Traded in my '20 Laramie CC on my '21 TRX. Had it about 2 months and even my passengers notice a difference in the A/C temp. I've had several people comment on how much colder the A/C is in the "new" truck vs the "old" one.
