AC not cold enough, help

[Eric2022]

Hi everyone have any of you had any issues with your air conditioner? The air conditioning in my 2019 RAM Limited just isn’t cold enough for some reason and I was wondering if this happened to you or if you have ever heard about it and what the solution was. It’s sort of cool but not cold, it doesn’t really cool the cabin, and the only way it becomes semi comfortable is when it’s on full blast. I have all windows tinted including pano sunroof the problem is with the air being simply not cold enough I can tell when I put my hand up to the vent as well. Thank you for any advice? I was thinking about getting the recharge cans they have at autozone does anyone think that will make the air colder when it comes out of the vent? Thank you very much.

There are multiple threads about this. There appears to be a lot of people experiencing it.

First, unless those recharge kits are specifically for R1234YF systems, as opposed to R134a (which I'm almost sure they are), you can't use them on your truck.

Secondly, it's customary on forums to try searching for your particular topic of interest before posting a new thread. We have no shortage of threads on the A/C problems, such as:

Air conditioning performance

Well, dropped my Ram off at the dealer for a couple of issues this week, one of them was poor A/C performance. I realized I've had my A/C on "lo" temp and recirc almost since I bought it, which is not normal. I've also noticed that the air coming out of the vents when on non-recirc feels a bit...

RAM AC poor performance TWITTER/FACEBOOK

PLEASE! All of you with AC issues I implore you to hit up RAM Trucks on BOTH Twitter and Facebook! My dealer performed the “TSB” update to appease me but my issues still remain. Today I posted on both Twitter and Facebook. Please do the same! Collectively we may have a better chance at a...

AC - does anyone have a truck that blows ice cold?

I know we've heard from those with AC issues but is there anyone that does not have an issue with the AC? Their truck blows ice cold air similar to other vehicles they've owned when it's warm/hot.

Potential work-around discussed here:

Air conditioning Hack

Today I was able to get 36-38 degrees blowing out of both the drivers side and the passenger side ac vents. Previously I was getting 44 out of the passenger side and 50-52 out of the driver side. I installed a water shut off valve in the heater hose going from water pump to the heater core. It's...

Cliff's Notes: There appears to be an issue with the blend door not completely sealing off airflow through the (always hot) heater core, resulting in warm air being mixed in. This usually manifests itself with higher vent temps on the driver's side compared to the passenger side - sometimes as much as 15 degrees difference.
Dealerships, by and large, are going by a manufacturer's spec. sheet that "allows" for these higher temps, pronouncing the system as "working according to spec.", and sending the owners on their merry way. Some members have taken it upon themselves to shut off the flow of engine coolant to the heater core, resulting in much colder vent temps. This is a viable, albeit temporary (some would say "hacky") solution to the problem in the hotter months.

Anyway, read up on the linked threads, have your dealership at least give your A/C a once-over (you may actually have a low charge in the system, rather than just experiencing the blend door problem), and go from there.

Thank you so much for this very detailed reply it gives me what I need to get this taken care of.

A member has developed their own "fix", but it's a do it yourself not FCA approved one.

So I decided I wasn't going to let the dealer rip my dash out for no reason and I came across this on Amazon. https://www.amazon.com/dp/B092YVQS7K or, you can find it by searching for "Muzzys A/C Hack Kit". For 20 bucks you really can't go wrong! I live in AZ and we're almost up to 100 degrees here already and this made a world of difference! I no longer want to get rid of my truck.

Im one of the people that put a valve on the heater core and it works pretty well. Not as cold as my last 2 rams, but much better than it was (~8 degrees cooler if memory serves me correctly).

Pulling a dash isn’t rocket science.

Sure, some folks have had damage from apes working on their trucks, but vast majority have not had any issues and have colder AC as a result, without having to jigger rig their warrantied trucks like it’s 1981.

Well worth getting the TSB. Done. I’d do it again in a heartbeat.

Cheers
