A/C Issues? Anyone else

[flan]

Does anyone with knobs that control the climate system (tradesman like mine) have any ac problems or is it more the touchscreen climate guys having the issues?

 

[OuachitaAdventure]

Mine has knobs.

Mine has knobs.

I think it's a design issue. From my testing on my 2019 3500, the high side pressure from the compressor is lower than it should be. I verified it had proper system charge, per the label capacity. I fully reccoved the system, evacuated for 44 minutes and charged it with an added an extra 0.2lbs of refrigerant over label capacity. When I did a performance test after that, the low and high side pressures initially got close to where the should be and the low side went back down. I believe the body computer monitors and control the compressor clutch circuit and it is disengaging the clutch at too low of a pressure. I am also trying to find specs on the expansion valve because it has a different part number than the one on my 2016. I want to replace it with one with a different superheat rating and see if that makes any difference as well.

You are way above my expertise...lol.

I have been certified in R-12 and R-143a service and repair for 20 years haha. I've seen a few things and own all the equipment for it haha.

So new issue to go along with subpar AC on hot days...I was driving into work around 7am today. The outside air is in the low 60s. Too cold for the AC to be blowing right at me, I changed the blower to the windshield. The manual temp was set to 62, and the windshield started blowing HOT. I had to revert back to the face vents because it was unbearable. These HVAC issues have completely sucked my enjoyment out of this new truck.

I had that happen on my 1500 one time. I had to turn the truck off completely for it to correct itself. It was blowing ac in the middle of winter. It did actually seem cold then though, lol.

 

[RamCares]

I have 2019 Big Horn Crew cab and noticed the A/C not cooling as I would expect, I basically have to turn it to max to try and keep up even on mid 80s days. I noticed it right away when I received the truck.

Hi ramblinman,
If you plan on having this addressed by your dealer, we would be happy to get you connected with a case manager to assist throughout this process. If this is something you would be interested in, please send our team a private message!

Hi- I mistakingly created a similar thread linked here:

A/C issues

Hello All! First post here in the forum. I recently purchased a 19 2500 w/ the Cummins and have been very displeased with the performance of the a/c system. I live in Texas and the a/c just can’t keep up with the heat it seems. I returned the truck to the dealer last week and they said they...

hdrams.com

My situation is similar to a lot that are previously mentioned, terrible A/C performance. Dealer evacuated/recharged the System and said it was working to spec. I was unable to notice any discernible difference.

Super bummed about the a/c performance, my 17 1500 hemi would freeze me out of the truck.

My effort for RAM to help the ac pretty much ended today. Been with the dealer almost two weeks. Reached out to RAM executive they were very responsive however was called to pick up the truck today they said the ac was fine to roll down the windows during hot days to let out the heat, dont use max ac and set fan on 4. Drive around a bit then roll up windows. They said they were able to get the cab cold. I tried it truck behaves the same to me. Its cool but not cold like I think it should be. Nothing else I can do will prob trade it in for one of the new f250 coming out and take the loss. Thought you would want to know how my journey ended.

Thanks for the info. I am supposed to have a conversation with someone from Ram over the next few days. I went out on a limb getting another Ram after my issues with my 2019 1500. Sorry to hear they couldn't get your issue resolved.

That’s really stinks! I am still hoping Ram will come out with a fix. There is no way they can expect us to pay 70k for a truck with piss poor a/c.

Agreed. I've been eyeing the new GMC hds. Got me thinking....Duallys aren't out yet, but I saw a 2500 denali with a payload of 3k and change. That's considerably more than a Ram 2500.

Well if the F-250's have the same A/C as the F150's I still think you are going to be disappointed as my F-150 hasn't had cold A/C since day 1 of ownership! I have to do exactly like the quote above to cool off my truck. I have a 25-30 min commute home from work and the A/C finally gets cool about 3/4 of the way home.

I talked to Ram today. I was contacted by a customer service specialist after talking to Ram Cares through PM. They contacted the dealership and got all the details of my case then called me to discuss. Long story short, everything is "in spec." I told the rep that I agreed that it was probably "in spec", but that I wanted them to reevaluate the "specs". He offered for me to get a second opinion, but I don't think it will be any different than the first time.

I told him my main intent for contacting him was to put this issue somewhere in writing. I asked if there had been any trends or other instances of people having this same issue. He said there was not. I told him that I hoped by documenting this issue and that if others did the same it could possibly lead to FCA making a change. I referred him to this thread and told him that I didn't think this was unique to my vehicle.

So, for now it's not an issue to Ram. The only thing I can suggest is that more of us with this issue speak to. customer rep to properly document the issue. Maybe, somewhere down the line FCA will issue a fix.

@RamCares, lying is not a good look. A sad turn to say the least.
Hopefully it's just one bad employee.... but sadly he was trained to answer that question by someone higher ranking. There are so many documented cases of poor AC performance in the 2019+ Rams, HQ ignorance to it has not been possible for many months.

Well, I can't say whether the particular employee I spoke with was lying or not. It is possible he was unaware, which is why I referenced the forum. I am on several Ram forums, as well as many of you, and it seems like there are many of the 2019s in 1500s, 2500s, and 3500s that are experiencing similar issues. Hopefully, this and all the other threads in conjunction with a documented claim with FCA can help lead to a resolution. It seems like there are a lot of examples , but people on forums are probably a small percentage of actual truck sales.

That's a good point.... it is unprovable. FCA/Ram Corporate Customer Service Teams use a centralized database for vehicle issue tracking though. Maybe he misspelled AC when entering your case info. I kid I kid Joking aside, Ram Customer Service is fully aware of the reputation its 2019+ AC's are building out in the customer wild. Even if one was to turn a blind eye to all the active and inactive customer case numbers for AC performance in the system, the wording in the Ram cable shared by Savaytse66 is another lens onto Ram's awareness of AC performance issues. Pasting down for convenient ref: "Engineering is working on improvements for the performance of the
vehicle HVAC system at this time. There is no ETA on a system update or release at
this time."

It's awesome that you are methodically following the steps to ensure continued documentation of the issue. Ram Owners like you will be the key to getting a factory sanctioned fix that will benefit everyone. It seems like RamCares has/is also trying to help keep visibility on the issue by ensuring case numbers continue to be created for the many Ram Forum Users experiencing AC problems. It is also valuable for RamCares to know corp CS reps getting pulled into the process by virtue of the RamCares spotlight are at times pleading ignorance to the existence of AC perf issues on Gen5 & 4.5 units. With Ram forum participants who have likely seen the many AC performance cases created throughout the year, it only hurts their credibility. It's also good training improvement scenario to use with that particular employee.

This guy found a solution to weak AC.

 

[IronByron]

I have been following this thread with concern that this is something I would be dealing with on my 2500. For those having issues, did it work then degrade over time or never work? My AC is working great currently and obviously hope it stays that way.
