Anyone else's AC not blowing cold?

Mine hasn't been feeling cold so today I compared it to a GMC. There was a 20 degree difference.

It must be the fan clutch, my 2012 was the same way but would cool down while driving.

It's a proven fact that the new refrigerant does not blow as cold as R134A. It think it's R1234yf or something. It's a scam, because Dupont's patent ran out on R134a, so all of a sudden they found out it's really bad for the environment (like R12), but they just so happen to have developed this new patented one that's much better for the environment. This is the crony capitalism that we need to get rid of in this country. I'm a capitalist, but not a fan of this corruption. /rant

Being a Commercial and Industrial air conditioning man since 1980 I feel the same! It is all a scam in my book just like R-22 and now 410A on your house unit. Scam so you'll have to buy new equipment.

Call your dealer....I read somewhere on here or another forum....that there is a TSB out on the 19's for not being cold enough...something to do with the blend door not opening or closing as much as it should and they fix it with a flash....BCM I believe.

Thanks! One of the first things I noticed on my 2019 was the slightly warmer AC. It still does the job, but it is definitely not as cold as my 2016 was.

I lerk around here because I'm always hoping to come back to the Cummins family.

That said, my 2019 Toyota Tacoma has the coldest AC I've ever had in a vehicle. It's amazeballs. I was idling for 30 minutes in Florida heat a couple weeks ago, and it kept the temps cold as ice.

I don't mean to rain on your 'new dang-fangled democrats-suck rant,' but it is what it is.

OP, if your AC aint blowing cold, either something's wrong, or that's just the way it is in these new Ram trucks.

Wow, what an imbecilic post. "Amazeballs?" LMFAO.

Let me ask you - how many years have you worked in the HVAC industry?

Further - "democrats-suck rant?" If you knew anything about politics you would have easily recognized that it would stand as an attack on both parties - the fake science/climate change-loving left, and the crony-capitalism-loving right.

I will ask my dealer about the TSB. Something must be wrong. Refrigerant conspiracies aside, if other vehicles can blow cold, my Ram should be able to also.

While at the Ram dealer today getting my tire fixed on my dually I checked out a 2019 dually 4x4 8ft bed CC Aisin. Black leather interior with heated cooled seats. I started the truck A/C on high recirculate. Let the truck run for 20 minutes while looking over the outside features and engine and really killing time BSing with the sales guy. Got in the truck and it was still hot inside and was very disappointed. I didn't care for the truck anyway because I like rubber floors and don't use my truck for mall hoping. Anyway my 2015 dually would have been plenty cold so the new ones have a issue that's for sure. I also notice it didn't have the leg room my truck has. This truck was supposed to be set up exactly like mine but at Larimie trim level. They definitely changed the interior up with a lot shorter leg room. I'm tall so that is another issue besides a messed up A/C to boot.
