Prospective buyers beware

I tested mine a little while ago. 37F outside today. HVAC set on 60F, manual mode. Blew hot air until truck warmed up, then air cooled to normal after that. Ran temp up periodically as I drove and you could feel air getting gradually warmer. Seemed very normal to me.

Auto mode sucks, but at least it'll warm the cabin well.

I'm confused. In manual mode, set at 60F, the air temp changes instead of blowing 60F air? What you've described sounds like auto mode to me rather than manual.

Me too, on manual mode the car shouldn’t have to warm up to blow cold air. Heat... yes if it’s really cold, but for AC that doesn’t sound right.

how long did it take to start to get cold?

On the JT, just like every vehicle I've owned with auto A/C, there is no manual mode. "Auto" means everything is automatic. Hit the fan speed and the direction and temp stay in auto despite zero notification otherwise. Same if you hit the airflow direction, fan speed and temperature will still be automatic. Hit both and only temperature will be automatic. The only way to get temperature to do specifically what you want is to dial it to LO or HI, with nothing in between. Not saying I agree with it, just how it is.

I'll try to pay more attention to our 2015 FCA Dodge Durango Citadel, though I seldom drive it. Happy with the HVAC in that car, as is the Mrs (it's her car, really). Conversely, she really dislikes the system in our Toyota Venza, which also has an automatic system.

I’m glad you posted this. I think it describes what I have felt almost exactly. The only difference is it doesn’t take 30 minutes. Maybe 10-15. Not sure where you are located. I’m in North Jersey maybe its just a matter of the local temp. Also, mine does seem to go back to warm air eventually but it takes a while. It almost feels like the computer pumps out hot air maybe 80 degrees to warm the cabin up to the set temp of 70. Then when it gets to 70 it stops pushing hot air but instead of putting out 70 degree air to hold it there it puts out 60 degree air. It is cold enough that the vent I had pointed at my hand made my hand so cold I had to move my vent. Raising the temp a few degrees got the air hot again but in a few minutes it was cold. It’s very annoying but I have only drive the truck a few times since it is new. This seems like poor tuning of the brain of the system. Hopefully, there will be an update.

I have noted one thing so far, maybe two, unsure of that though. One thing I DO note for sure - I leave it on auto most of the time. And it does a good job getting to temp. But once it's been running for a while, say I've driven over 30 minutes and it's warm in there, it kicks down and then you feel cold air blowing in and it doesn't warm back up again. Say it's set at 70 degrees, it does a good job of getting there, then settles down and maintains, then after a while it's like it kicks off and my wife even commented, I feel cold air now - and we checked the temp setting and it was at 71 at that time - yet you could tell it was cooling off in the cabin.
Choose defrost like I had to this am because the windshield was getting iced over fast and it kicks the fan on high, air gets really hot out the middle of the defrost, then you put it back to auto - and it doesn't get up to the temp you had it set at. Seems auto works fine at first, then kicks out and doesn't maintain that temp once it reaches it. When I hit defrost on part of our trip this am and then set it back to auto, it didn't stay at the 71 she had it set at and we both looked at it like what the heck? Why are we feeling cold air - the heat isn't even really on.
In short, auto works best, works fine until you change something and go back or until it's been on a while, then it drops back and doesn't maintain. You can manually manipulate it and get it warmer in there like she did, but auto did not maintain temp today.
Short runs under about 30 minutes it works great.
I originally thought it was working great, but after today and after realizing - hey she's right - it's not KEEPING it warm once it gets there... like it ramps up and kicks out hot air until it reaches temp, then back off and can't heat up again, like something sticking.

Hard to go to dealer with it because so far it's "just a gut feeling" that something isn't right. I need to actually track it better.

Since the temps here have been winter since I picked it up, never a need for AC and have run heat every time I've driven it I can't say how it would act outside of a cold day.

On mine, I have noticed the cooler air also. Not ready to say mine is bad. On a long road trip, I felt the cooler air after the temp was set. But, it never let the interior temp go cooler than what it was set at. The wife had her side set warmer than my side. I reached over and could feel the warmer air coming out while my side was still cooler. Maybe that is why mine was cooler. When alone, I keep the temp the same on both sides. I think the temp setting is for the interior temp. It warms up by blow super hot air, then cools down the air to maintain temp. Just my opinion. Maybe right maybe wrong. I have never used the Auto feature, only manual mode. But, I have not seen anyone post that they have used some type of thermometer to measure temperature of the air coming out of the vents. I currently do not have that capability, otherwise I would check it out myself.

Please read your manual before you spread incorrect info as you did in your above post.

Please refer to page 72 of your manual and it will describe the manual mode in which you INCORRECTLY claim doesn’t exit.

It’s simple, set your temp to desired temp, and it should be that temp. Set your desired blower and it should blow at that speed.

Our vehicles aren't working as described in the manual. This is the point of this thread.

You beat me to it and said it better than I would have.

Auto is auto - it controls the air mix, heat OR cool depending on need, it controls and CHANGES fan speed, etc.

- manual is manual, you set the fan and it stays there until YOU change it in manual mode.
Set the temp and it stays there, but it's manual for fan and heat or AC choice.
In manual mode if the temp skyrockets to 90 degrees outside you have to change it to AC to cool off.

With my Chevy, and I suspect the JT - I don't KNOW - but suspect, in auto, it will change from heat to AC as needed if you set the temp to 70 and it's cold, it runs heat, if it's hot out, it runs AC, automatically.
That's how my Chevy did it - I set the temp and left it all year long, left it in auto mode and one day the heat would run, the next the AC might be on, depending on outside temp.
In manual mode I had to choose heat or AC and I controlled the fan speed.
Auto mode did all of that for me. With my Chevy literally it would run the heat in the AM then in the afternoon, it would run AC because it was hot in the cab from the sun shining in and the outside temp had jumped (it's Iowa, too cold for you, stick around a few hours)

Now I'm suspecting that's how these JT systems work as well.........

Those specific pages are covering the manual, single zone a/c system in the base Sport model not the automatic, dual zone a/c system on every other model.

Granted, I've only had my JT for three weeks and it's spent almost all of it's time in auto. I tried this experiment in my Honda on the way home from work today (and had previously done it on my old Canyon) and will try it on my truck tomorrow. Put it in auto, adjusted the fan speed to knock "Auto" off, then crank the temperature up or down and see what changes. In the GMC and my Honda it would keep the fan locked but adjust the temperature and direction automatically. Then flipped it back to auto and adjusted the air direction to kick it back out of "Auto" then crank the temperature up or down and see what changes. In the GMC and Honda, the fan speed changed and the air temperature coming out of the vents will change but the direction won't. If I can find my thermometer I'll dick around with that as well to see if and how much the vent temperature changes.

Also, like I said here or in the other thread: I'm not agreeing it's the best way, just seems to be the common way and if it's still blowing warm/hot air at 72 degrees but it's clearly above that in the cabin, something isn't right.

The manual mode is still the same I described on the 7 and 8” models. The manual mode is still (per the manual) supposed to do as I described. The only difference is When your in auto mode, you push the auto button, to turn off the light off which then goes into manual mode.

Just to clarify- when you push your auto button or change the blower speed, this “kick it out of auto” you described is putting it in manual mode.

Can you clarify your comment “the fan speed changed and the air temperature coming out of the vents will change but the direction won't”?
how I’m reading it your saying somehow in manual mode the fan speed is changing the temperature. That should be the case. In manual mode the blower controls the blower speed and the temp controls the temp, this being in manual mode. In auto mode you choose the desired temp you want to the cabin to be. If the cabin temp is close to the desired auto set temp, the blower and temperature coming out won’t be as extreme. Compared to setting it at 82 when it’s 30 out, the air should be blowing pretty hot and the fan speed should be high to move the air to accommodate the large variance.

Its on page 72 of both manuals. I have attached the other manual for your educational pleasure.

When I'm saying "kick it out of auto' it's kicking it out of full auto where it's controlling temperature, fan, and direction. My previous vehicles have had just varying degrees of auto with no fully manual mode and I'm assuming this is the same (but am planning on testing it tomorrow). What they have done is that if you adjust the fan speed, the auto light turns off but the temperature and direction are still in auto despite there being no notification of such. Same thing if you changed the direction, the fan speed and temperature were still automatic and if you changed both, the temperature was still auto with LO or HI being the only way to force it to something, which seems to be what the complaint is here.

Please read my above post. There isn’t a “full auto” and then a “partial auto”. When you push the auto button off it should go into manual mode, as the manual states. I’m not sure why you keep assuming things contrary to what the manual says.

You can’t change the blower speed in auto mode. In auto mode you only set the temp, that’s the only variable. You set the desired temp to what you want the cabin temp to and it does everything else.

Here are some examples because I’m not sure your getting it. In auto mode, the following should happen:

1) it’s cold in the morning, let’s say 30 degrees. You set auto to 75. The blower speed will be high and the temp coming out will be fairly hot because the variance between the actual and desired temp is 45 degrees.

2) your car is parked outside and it’s 77 degrees. You set auto to 72. Cool (not cold) air should blow our fairly light, trying to drop the temp the small variance of 5 degrees.

3) your car has been in the sun and it’s 100 out. You set the cabin temp to 65 auto. The variance is 35 degrees. The air should be cold and blower should be high trying to accommodate the large variance.

If you press the auto button OFF, you can adjust the blower at any speed 1-7. Blower doesn’t affect temp. Only temperature controls control what temp is coming out. If you set to 80, 80 should be coming out. If you set to 61, it should be cool/cold air coming out.

Hope this helps, happy new year all!

I realize it's called "manual mode" but I don't think it's full manual. I did get a chance to mess with both it and my other vehicle on the way home from work Tuesday and yesterday. The JT does not have the partial auto that my other vehicles have had where it'll still control whatever hasn't been manually adjusted between fan speed and location, where if you adjust fan speed and it'll no longer control distribution either. Admittedly, I couldn't find my thermometer to pull quantitative data but it felt like the temperature didn't go to a temperature and stay there (set at 80 and it blows at ~80) in either vehicle, more that it followed the same logic it would if in auto. The "Auto" button description in the manual also doesn't say anything about changing how the temperature behaves just says it "adjusts airflow distribution and amount."

Please read the full thread. It’s not a “Jeep thing”. Does yours blast heat to the point your hand feels like it’s going to melt when it’s set on manual at 61 degrees? That’s not about perspective... that’s called something being wrong. Is it in every Jeep? No. Is it many people’s Jeep? Yes. It sounds like you’re doesn’t do. It’s NOT helpful when you respond to an issue you aren’t having and you CANT speak to. Your above post did not add any value to this thread.

“Minor issue” is all in perspective. I’m sure it would be a major issue if the furnace at your home pumped 90 degrees every time you turned it on. It would not be a welcoming nor comfortable home if that were the case.

OK, its coming out that hot, then 1: turn down the fan speed? 2: don't aim it at your hands? change where the air flows? My jeep has the same issue with the HVAC. Sucky HVAC isn't a jeep thing, most cars nowadays have under performing HVAC systems.

So my post about my personal experience with the issue the thread is about doesn't add value, but your post telling me that my post doesn't have value, does....? Cool.


If you really want to compare Jeeps to houses, ok. In my house, the one unit air conditioner doesn't reach one of the rooms in the back real well. Your equivalent is going out on the street on a soap box and yelling about how poor the design is, hoping the architect hears you. While im saying to you, "yea it suck, but maybe just put a fan or two in strategic places"

I agreed with you. The HVAC isn't great. But in MY PERSONAL EXPERIENCE I had no issue adjusting certain parameters of the controls to gain normal use of the errant system.

This click bait repost war rages every day in all corners of the internet. There was already threads about this. You could have easily added your experience to those. But you want your own thread? Cool, no prob. But then you make a trashy Click bait thread and are confused and defensive when it takes heat.

With your logic if my steering was backwards (left to right) you would be telling me to get over it, and to just turn left when I want to turn right.

But maybe I’m over reacting because this is just Jeep things we all should expect, right?

You won and made your point that you have very, very, low expectations of Jeep, I think we all get that now.
