Heater/AC blowing hot air at 60 or higher

[Hootbro]

any updates? ...any resolutions?

It's still cold winter in most places and I would not expect the issue to be pushed until it warms up and is a more annoyance again.

Might as well jump in too. Picked up my ordered JT rubicon on Jan 31st. Here in Southern California we do get summer hot days now and then even in Feb. and I like driving around with cool air blowing in my face from the AC. Never had a problem with this in any of our other 5 new vehicles we have gone through over the years (yes I am an old fart). My very first experience with the AC in this beast was a blast of Death Valley hot air to the face. Man! I couldn't get to the controls fast enough. I set them all the down to the coolest setting and finally something cool hit my face. I dare not set the temp above the mid 60s for fear of getting baked again. Something isn't right with this AC system. How this can be an issue in these times is beyond me. I mean automotive engineering has come a long ways and I thought they figured out vehicle AC systems a long time ago? This is definitely a step backwards.

I've read though all 12 pages of this thread and think the best course of action is not to do nothing and just wait for the TSB. There won't be a TSB unless we all take our problem to the dealers so our complaints can be recorded. Of course we are up against it, no car manufacturer wants to be responsible for repairs on their buck, it affects their bottom line, especially with FCA scandals and with the company's income sliding the last three years. You don't want to be the executive writing up a recall and causing a major expense at this time. So, its incumbent upon us to be somewhat of a pain in the rear to them and keep harping to them about this. I mean to not get the AC right? In this day and age?

It would be helpful if you could repeat the experience - close the dash vents first to prevent the burn- and document exactly the circumstances and dash settings so we can all verify if the same conditions are present on our JTs. Cold start? Or after warm up and been out driving for a while? Blower speed, temp setting, dual mode, auto engaged?

Mine is: blower speed doesn’t matter, whatever it is; dual mode is on; auto is not engaged.

Mine will often blow baking hot at 60-degree setting. After a while, in under 40-degree outside temps, it will settle in so that the 84-degree setting blows cold.

So, when doing long highway driving in cold-to-moderate temps, in order to make it comfortable, I am in the following four settings 95% of the time: HI; 84-degrees; 60-degrees; and LO. Usually, 60-degrees to 84-degrees is either way too hot or way too cold.

So, I usually am either toggling most of the time from HI (too hot) to 84-deg. (too cold) or LOW (too cold) and 60-deg. (too hot).

There obviously is an error in all of this. I have driven hundreds of rentals and owned many vehicles and never had it be this difficult, including many other recent FCA vehicles, and dating back to my bad-ass 1974 Monte Carlo.

I’m not in despair, but it is a defect. On any other vehicle, I could turn the heat up or down gradually in temps below when AC is needed; you pick one; and it stays comfortable for a while.

For this one, when it’s cold outside, the lower temps start out burning hot, and then cool down until, eventually, the 84-deg. setting is blowing outside air at outside air temp (e.g. < 40-.deg.), and then I have to switch between HI (near welding-torch temps) and 84-deg. (< 40-deg.) in order to keep from freezing or burning up.

Hey, it keeps me awake and active on long road trips—constantly pushing climate buttons. So, it may have saved my, and many other, lives.

But it’s annoying.

Just took delivery of our 2020 Gladiator last week and absolutely love it!

Has anyone had issues with hot air blowing out at settings of 60 or higher? If we bring it to Low and begin feeling cooler air and then increase to 65 it's fine for a moment. Then, hot air begins to blow and it feels the same if we have it set at 65 or 80.

Dealer looked at it and told us no codes showed up when analyzing and that there have been no issues reported, however this doesn't seem right. They recommended we drive it for a bit and see what happens.

Any thoughts on this would be appreciated. Thanks!

I had a 2018 Wrangler a 2019 Ram and now a 2020 Gladiator. They all have the same strange HVAC gremlins. I swear they are possessed sometimes. They all heat and cool, with the exception of my old 2013 that heated the passenger and froze the driver, but that’s a story for another day. Anyway, the newer HVAC systems, I believe, are functioning properly, or as designed. I think it’s just some strange programming. Probably something to do with longevity, economy or some other nonsense. You get used to it after a little bit and learn how it reacts.

I regret to hear of this concern so soon in ownership, BajaDrifter. Have you brought this to the attention of your dealer yet for diagnosis? If not, we suggest doing so at your earliest convenience. Please let us know if you need any assistance.

Thanks for the comment, Kate. The challenge with this behavior, as many of us have described on this thread, is that it takes a specific set of steps AND pretty much requires that we drop our vehicle off and the dealership AND hope someone there is interested in following the steps to reproduce AND hope for the right weather conditions to reproduce the behavior.

I get that Jeep wants to reproduce these issues before they can issue recalls and fixes, but in my case, my vehicles have spent far too much time at CDJR dealerships only to have them say, "sorry, we can't reproduce it, so we're not going to do anything." In the meantime, I've done without my vehicle for days, most times without a loaner.

I believe if you all really did care, you could get a few dealerships in the south to follow these steps:

1. Set the HVAC to manual.
2. Set the AC to on and leave it on.
3. Wait for a cool morning (somewhere between 30 or 40 degrees F).
4. Take the Jeep for a ride with the temp set between 68 and 73.

What I'd expect in that scenario is that the vehicle maintain a temp of 68 to 73. Instead, what I get is full blast heat, as hot as the vehicle can muster, until the vehicle engine comes up to full operating temperature. At that point, the HVAC system starts to recover. Note that if you lower the temperature to LO, it will blow cold air, but as soon as you even bump to 60, the full heat effect comes back, until the engine comes up to operating temperature. On certain mornings I have to jump between LO and 60 just to keep things comfortable until the system straightens itself out.

Most of the solutions here have been some combination of the following:
1. Use the Auto, you moron, that's what I do. To that I say the manual setting should work. It does on my 2006 Jeep, it should on my 2020 Jeep.
2. Turn off your AC, you moron, it's winter time. To that I say, live in the south for a while where we have humidity all year round. There are many times when you need the dry air AC provides to keep your windows safely cleared.

I believe if Jeep really cared enough to follow these steps on a set of vehicles you already have, you would find you could reproduce this issue. Then I'd hope your wiz kid programmers could reprogram the HVAC system to not require the HVAC hokey pokey in the mornings.

Eloquently described. Jeep Cares replies... yet nothing happens except a referral back to your dealership that doesn’t care to duplicate the findings.

I would like to take a moment to clarify for you all that JeepCares is the Social Engagement Team for FCA. We monitor forums, as well as social media platforms, to assist customers who are currently experiencing vehicle concerns as well as get them connected with a Case Specialist to work with their dealers throughout the repair process. We also track trends so that the appropriate parties are made aware of what concerns our customers are experiencing. That said, we are not trained technicians and I am unable to provide repair steps to customers or dealers for concerns. With this in mind, if anyone would like assistance getting their concerns resolved, I am just a private message away.

I appreciate your response and I recognize your limitations, unfortunately it baffles those of us experiencing problems that there can be 12 pages of people complaining about the same issue yet all of us who have brought our Jeeps back to the dealer have been met with a shrug and sent away unsatisfied. Clearly there is an issue, we’d hope that jeep cares could communicate with whoever needs to know so a problem could be fixed, instead of just going through the motions.

My thoughts exactly. We appreciate your input, but unfortunately there's a perception that Jeep doesn't proactively address these issues. From my perspective there is zero motivation on Jeep's part to address this kind of concern until it becomes an issue that they may become a litigation issue. The perception is that Jeep doesn't care until they're made to care.

Just chiming in here because I have the same issue. Hot HVAC at any temp other than low. Is there some sort of petition or something I should be signing? What a pain...

 

[Duke56]

I’ve found that “Auto” seems to work best and is more consistent. I had more issues in manual and with heat directed to dash and floor.

 

[WJTR]

Jumping into this thread with the same exact issues that everyone else is reporting. Piping Hot Air is a constant. Our Gladiator is a recreational vehicle that we dont drive much so we haven't yet felt the necessity to contact our dealership. Hoping someone on this thread can report a solution.

 

[Duke56]

I have had the same issue and found that if I leave it in Auto mode it doesn’t happen. In my case if I use manual mode then I get the problem and ONLY if I direct the air to the dash vents.
It seems if you use only the floor vents in manual then it’s OK.
So the conditions I’ve found wherE it occurs is:
Manual Mode, with Dash Vents or Dash and Floor Vents = TOO HOT.
