AC issues fixed for 2020???

[ldoh]

I wish people would quit acting like it's some grand FCA conspiracy to keep temperatures high in the specs so they don't have to do anything. We should hold companies to task when they are really trying to screw us but also call a spade a spade when it is on the level.

I pulled out my Genuine Nissan Titan service manual and opened it to the AC performance section. The recirculation to discharge temperatures, at 50-70% humidiy, is as follows:

Interior temp 77, vent temps 47-55
Interior temp 86, vent temps 55-62
Interior temp 95, vent temps 62-70
Interior temp 104, vent temps 73-83

Those specs are HIGHER than the Ram:
Interior temp 70, vent temp 45
Interior temp 80, vent temp 45
Interior temp 90, vent temp 55
Interior temp 100, vent temp 55
Interior temp 110, vent temp 64

The idea that the temperature specs are some kind of company conspiracy is laughable.

What's the source for your "Ram data?"

Those Ram numbers are lower than what some dealers have told customers. Some here report the dealer say ~70 deg vent output temps indicate the system is functioning as expected.

So, I'm kind of bored today. I looked at another Ram forum and there's a thread "What don't you like about your Ram" 15000 views, 24 pages of "complaints". One mention of a/c. No likes on that post and no one quoted it, good or bad.....
I'm thinking if it is a significant problem across the entire line with more than a year and a half of production now, it would get a bunch of posts in that thread. Just guessin

So why are there several threads with hundreds of posts on this very site concerning the AC performance? Probably because some of the trucks have an issue. Just guessin...

If you don't have a problem, that's great. But you and others spend an awful lot of time trying to convince us that there is no problem with the AC in any Ram.

My AC works great and I live near KY lake where we 90+ temps and 90+ humidity. I set it on 68 and never touch it. It might be a real problem for some but not on my longhorn

 

[Twister]

Hey man, have you actually measured your temps, or are you just saying we're all full of ****? People aren't stupid and can generally tell when something is different (AC performance being poor vs other vehicles). Hard numbers don't lie though.

I've had THREE 2019 RAM Limiteds, build dates of 5-18, 12-18, and 7-19. All of them had **** AC (driver vent temp was about 54, passenger temp was a few cooler). Two of these trucks I used the clamp method to dramatically reduce flow through the heater core (but not cut off entirely). IMMEDIATELY dropped temps in the 40s. Please explain how I had 3 trucks with the exact same issue across varying build dates, and they were all problematic?

I'll tell you. Because that's the way the current design functions, and it's not good. I don't care if you think most of the trucks are okay, because my unique experience (which is much more than you) says they aren't. I have a 2020 Limited being delivered to me today. Obviously won't be able to test the AC for awhile, but I highly doubt they've resolved the issue. Who knows though... between my 3 trucks I've also seen them change components mid model year to help with road and wind noise reduction, and add PPF to stop paint scoring from road debris on the front of the rear fenders. Maybe someone at RAM decided this needed fixed, but probably not.

and yet you bought three of them......lmao

I’ve had no issues with my AC. It does what’s intended and keeps the truck cool easily no matter what the outside temperature is. Been very happy with it.

Someone in the other thread posted the specs directly out of the Ram service manual. A dealer saying that would be lying unless the ambient temperature in the truck was well over 100 degrees. A good dealer should test the system in at least two different ambient temperatures to be sure it meets specs both ways. That should be easy to do in the summer, take a morning reading and an afternoon reading.

Not sure how y'all meant that to come across... Forums have plenty of informed members. It's just that forums are the "go to" place to complain which skews the actual overall satisfaction / quality of any vehicle. There are many members that join because they are gearheads/enthusiasts, as I am, and then others that troll or are only on to belly ache or find out about some kind of problem and then disappear.
When this a/c thing became an issue that some would never let die here and I have a truck that keeps me comfortable in the heat (I just moved from central Florida that averaged 120 days of 90°+ per year) I decided to ask the service dept writers what they were encountering. I know writers in Daytona Dodge and Fields Sanford. Neither have had a/c complaints to speak of. And the 3 dealers I've used for recalls and oil changes haven't had many complaints up here in Michigan. So I don't think there is a design issue for the majority of the 100s of thousands of owners. Not saying trucks can't have a/c problems. All brands have a/c failures. Anyway..... I still say there is nothing wrong with the a/c system as designed.

Dear Sir . . . you've taken ONE sentence out of a paragraph ! The least important sentence in my opinion too !
FORUMS (plural) is a HUGE Quantity of People - "all sorts of Opinions, tidbits of factoids, what-nots of left over info. from last year . . . you get the idea ? Generally speaking, Just a Generalization, not one to intentionally "rile up" folks for any reason, well unless their being intentionally belligerent at ME ! It's occurred once or twice in the past 4 years or so I've been in the Vehicle Blogosphere ! I got suckered into that back then and I try VERY HARD to avoid "in-sighting" others who seem to have an axe to grind ! I assure you, and anyone else, I don't "troll" unless it's from a boat and I'm fishing . I used to be a "well known" member with a different "name" & photo, but when my computer Crapped out, I had to start a new . Based on that past experience I choose now to sort of just be more anonymous !
Been in the "Dodge / Chrysler / Plymouth / Fiat Family ALL my Life . . . well, except for 9 years that I owned a Nissan Stanza - 1st new car since my Very 1st Car (also new), a 1971 - dare I say it?, Fiat 850 Sport Coupe . Loved that Fiat, by the way . Note . . . much of my writing skills I learned from a Navy Journalism C-School, well + some College writing classes - not my major though . Strictly amateur enjoyment . Take Care and lets all have a Happy and productive 2020 !
ps; Case you haven't noticed I can get "wordy" and the sarcasm intended to be humorous can be misconstrued . I "work at it" .

I recently posted that my 2020 Laramie ac was working great. Yesterday it was a warm 82 degrees here in Los Angeles. I took a 15 mile drive and I had the ac blowing on the lowest temp setting at 6/7 speed and it was just keeping the cab cool. It was kinda ridiculous that I had to pretty much max blast it to keep the cabin cool. I only have 2600 miles on the truck also. I placed my hand on the vent to see if my hand would get uncomfortably cold. Nope, just cool air, not cold. If I lowered the fan to lower than 6 it just got too warm in there and it was only 82 degrees outside!!!!

We will see with my A/C black truck and live in S. Florida, have yet to go through summer with it. I did have the A/C compressor replaced last month under warranty but have not gone through the heat of summer with this truck yet. Time will tell.

Hi Beatle9999 & Tender,

Please be sure to let us know if this is something you end up addressing with your dealers. We are more than happy to have this documented and connect you with a specialist who can provide an extra layer of support for that process.

I just traded out of a 2018 Jeep JL Rubicon into a 2020 Ram Rebel, and I can tell you that on the Jeep side of the house, there were also a lot of complaints regarding the AC in these units, however ultimately the problem was a result of the actual performance of the A/C system, but rather the fact that there was a flapper vent under the dash that would randomly let in outside air. This became an issue for people living in extremes of temps, either cool or hot for a large portion of the year. It was also an issue for those living in high humidity areas as well.

Some of the folks went through the process of actually disabling this flapper because the other issue, as in my area is that it would also let in the dust as well when offroading. I live in Phoenix, so we have the temps, and the dust as you could imagine. I'm not sure if the Ram also has this wonderful feature, but figured it would be worth mentioning.

Otherwise, I've tried my AC briefly, though temps are cooler now here in Phonix, so no real need to use it now but the AC did seem to perform well the little it's been on, but I dont have the "auto" temp selection, just a rotary dial as per the "old style" type of adjustment.

I can tell you that I did have issues with the AC in the Jeep, while very strong, it seemed like the temp senor was not in the right spot, because it was always either way too cold, or too warm. I never seemed to be comfortable with the auto adjustment just leaving it set at 72 degrees, for example. Anyhow, just my 2 cents worth.

Will do. My A/C compressor was replaced not because it was not working well, it was replaced because it was not working at all. Still don't think the compressor was the problem. I'm pretty certain it was electrical since they still had to have it for another 2 days before after they installed the new compressor.

Someone mentioned problems with cold mornings. They said even with temperature set high, cold air blew through the vents. I observed that this morning while driving during engine warm-up. It was only low 40F's but still felt cold air flowing through the vents while temp was set to high. That made me wonder if there are at least 2 blend fail modes. 1) allowing outside air to flow through the vents without normal cabin temp control. 2) improper control of hot engine water flow through the heater core. If so, the first fail mode is much more subtle than the second.

 

[Firepower2010]

My 0.2 cents worth. I have a 2019 Laramie with the 12" U connect, and have NOTHING good to say about the HVAC system. My dealer says cannot duplicate concerns, yadda yadda, however the A/C side I can say is lackluster at best, the heating side another issue, and on top of that "Auto" is useless. My truck will not heat the cabin unless it is on max heat, even if it's 40 degrees outside, and I set temp to 80 degrees inside, it still blows ice cold, only until I crank it to max heat, and if I back it off by even one degree, it's back to ice cold for me. After about 10 mins at max heat, and turning the fan manually to 1, I try and back off the heat to 75/76 degrees, and it simply will not hold it goes cold to hot, etc., it's as if it cannot read the interior or exterior temps to figure out how to keep temp in the cab. This is complete and utter BS, why even have temp control? why have "Auto"? makes not sense, but dealer says it's normal... NOW, I got a 2019 Rebel to drive for a week as a loaner, it had the 8.4" screen with the more basic HVAC system, and it was FLAWLESS, set the temp in "Auto", and it was completely doing it's thing the way it should.. I think it boils down to something to do with the 12" screen system, I don't know, but hard to argue with the fact that this Rebel with 8.4 screen worked perfectly..

Well I thought I would follow up with the AC thing. The AC on the new trucks is terrible in S. Florida. I had a black 2012 an never had a complaint about the A/C but my 2019 leaves a lot to be desired. Both trucks were black.

On the really hot days the A/C seems to take almost 20min to cool off, usually I am where I need to be before this thing starts blowing cold air. This was not the case with my 2012 and not the case with any Fords I have ever driven. The A/C on the new trucks leaves a lot to be desired for sure.

 

[Timeless]

Definitely struggles in high humidity areas.

It is amazing the difference in performance in different conditions. 95+ with 90% humidity and you will go 15 mins before being comfortable if not remote starting it first.

Drop that down to low humidity or 10 fewer degrees and it takes more like 5 mins.

Drop down both and you will be turning the vents away from you after 5 mins.

I also suspect panaromic roofs don't help. You can put your hand up to the roof cover and still feel a lot of heat.

Live in Fort Lauderdale. Oven-like with high humidity and heat index.

I run my A/C on Auto/Low - and haven't had any issues. Initial cool-down in a hot cabin is something I expect. When everything gets to stable operation - I'm 58 degrees out of drivers side/center console vent.

It frequently runs so cold, I end up bumping it up to 67-68 to not freeze myself out.

So I guess I'm one of those who got lucky (if luck it what you want to call it) and have no issues with my A/C that I can complain about.

Humidity is non existent where I live and the AC is still sub par, so I wouldn’t blame it on humidity. For me 90 deg or over I use the valve to shut off flow to the heater core, under 90 deg I keep the valve open.

58° out of the vent is terrible compared to most vehicles on the road! Further proof that most stating they got a good AC are simply satisfied with higher temperatures.
