RAM AC poor performance TWITTER/FACEBOOK

What do you need?

Are you sure about that or just saying it to convince yourself that it’s true. I sat in my truck for 10-15 minutes with a service tech and it just did get to 44 degrees. And that was at 8:00 in the morning. It haven’t even gotten hot yet. And he told me that my A/C was working in perimeters. I just looked at him like he was crazy. Listen I’m not stupid. This A/C has a problem, I don’t know if it’s the new type Freon or what but it’s not cutting it.

That seems to be the consensus at my dealership, the new eco-friendly Freon is not up to par. Even my 2 new Chevrolet's (both 2019 and use the eco-friendly) do not get icy-cold like my 2008 grand Cherokee and 2006 Tahoe did...

Well my wife's 2012 Maxima is 7 yrs old and puts my 2019 Ram's A/C to shame. They need to evac that new **** and put the 134 back in and that would fix the problem.

The heater core is bringing temp up to 58-60. The AC evaporator and current refrigerant will deliver 42 degrees or possibly colder vent temps if heater core coolant flow is bypassed/reduced. There are several ways to improve your cooling in these threads until proper blend door fix is available by Ram engineers. Several members have improved their temps. If you modify with a clamp or add a valve (or valves), understand that you do it at your own risk. Don't cut factory hoses so you can return to factory with no trace. The current R-1234yf refrigerant may not reach 28 degrees like R-12 or R-134A but close to 40 should be good enough to cool our big cabs.

My 2019 built in May seems to have no a/c issues, and it was 25c outside today. We'll see what happens when its 32c outside.

This seems like when they switched from r12 to r134. R12 provides better cooling than R134 and now the newer stuff may not be up to the task yet to provide the same level of cooling as R134. It may take a redesign of the a/c system to make it work better.
As pointed out in this thread it appears there is to much coolant flow to the heater core. But I also wander if the running temp is also to high if the thermostat is let's say a 200* one the radiator might need an upgrade and put a 180* thermostat in while restricting the coolant flow to about 50-75% of the oem flow and see how that does.

Hi Sbroussard69,
We do understand your frustration. If you, or any of your fellow forum members, would like to have a case escalated in regards to this A/C concern, please send our team a private message. Case escalations are used to track the volume of a concern as well as alert the appropriate parties.

I have AC issues. I have to blast the fan (on the low setting) to keep it moderately cool at best, and Atlanta summers are no joke. I've taken it to my local dealer and left it for a day, only to be told that perhaps it came from the factory with slightly less than the factory required freon. They topped it off, but it STILL isn't cold as it should be. This is pretty frustrating!

Hi Newguy,
Your dealer does have the ability to reach out to the STAR team. Having a case escalated ensures your dealer is using all resources available to them.

Hi Sbroussard69,
I do apologize. I did find the public post where you provided your VIN. We do not recommend posting VINs publicly as they are attached to your personal information. I have documented this for you. However, I do need some additional information from you so we can have your case escalated for further investigation.

Thanks Alex for responding. I'm assuming one of the Ram owners has already had a dealer start a STAR case given how common this issue is (TSB not resolving the issue). Can you please check and let us know. If so, can you respond with the FCA response to the STAR? This saves us a great deal of time. Thanks.

Don’t forget to post this on Facebook/Twitter. Let’s make it public. Class action lawsuit if needed! That’s the point of this particular feed.

Not on any social media platforms to complain except for this site . I had the a.c. checked last yr after buying it complaining at the dealer it was poor at cooling they did something to it and said they are getting great readings on temp so i assumed it to be good. Fast forward its 87 out in WV where I'm working and I have the a.c. on 6 to keep cabin cool and it doesnt even feel like its all that cool now that I'm reading this and sitting in my truck. My wifes 14 suburban blows ice cold Antarctic temps at medium setting and its enough to keep that beast cool .. How do I get added to that list now

If you have a probe thermometer, read center 2 dash vents as well as the outside ambient temp. If you have like 58 on drivers center and like 46 on passengers center, the heater core is causing the poor cooling. If you put a temporary non damaging clamp on the "out" heater hose from water pump, within 15 minutes you should see 38-42 range temps out of both center vents proving actual AC evaporator is cold.

Hi Jhill,
As previously stated to your fellow forum members, the way we communicate internally is through escalating cases. The more cases, the larger volume of the concern, and the more internal parties are made aware. I do understand that it can be an inconvenience to visit your dealership, however, it is required to escalate cases as a dealer diagnosis is the only way to provide case specialists with the most current vehicle specs.

For the record, whether one party or many are aware, it shouldn’t come to this. If it’s just one person experiencing a problem with the A/C in the truck, that person should be taken care of ASAP by one party without escalating crap. If he bought a new truck under warranty and it’s malfunctioning, it needs to be fixed ASAP! Not after 5,000 owners have complained!

I did another test with mine. Left the house with hose clamped and let the temp get down to 42-44. I pulled over and removed the clamp and temp at the drivers vent immediate went to 50-52. Hard to tell exactly on my thermometer, but close enough. Drove this way for about an hour. Did some shopping and then put the clamp back on before heading home. Temps went back down to 42-44. I videoed the entire experiment so I can have proof when I take it to the dealer. They will probably say it's within spec, but there's no denying my video documented temperature swing with and without the heater line clamped.

I do not have one . about the clamp, what will this do long term ? Can this be kept in till they find a fix and it can be removed?

 

[GOATinstructor]

I would not recommend changing the thermostat to a cooler running unit.

This could cause, at the least, issues with the engine running the fuel mixture rich.

Also, running 20 degrees cooler on the heater core will not result in an improvement on AC.

Stick with the clamp or valve ideas.

Several members found a clamp set tool at Harbor Freight that pinches hose flow with minimal damage. I have not tried it, but I am hesitant to leave on long term as it may fatigue hose so it won't open back up. Maybe for short term testing and to prevent coolant loss if taking apart hoses to add valves. Any of these experiments are at your own risk. Don't cut your factory heater hoses so you can return it back to stock with no trace when Ram resolves issue.

At this point I'll deal with having to turn it on full blast just to cool . thanks for the info !

Does anyone know how to shut the blend door manually, or add a gasket to the "door jamb" so that the door can seal off a little better? Last that I want to do is dumpster dive into my HD RAM's engine compartment every time I do not want maximum A/C!

I want to know why there's any coolant flow when the AC is on? Seems like the 3 way electric valves on the 18 and older is the solution.
