First 80 degree day here in Portland and it was having a hard time in my max steel overland w/ black interior. Kids were complaining in the back. Not only did the a/c seem weak, but the airflow to the vents in the rear was pretty low.

Re: 2014 Grand Cherokee Air Conditioning Problem

Mid 80's and humid here today. Now that I've figured out how to operate the a/c it keeps my vehicle quite comfortable. Select max/cool soft-key, and recirculate soft-key, and it cools down quickly. Also, on remote start, a/c turns on if outside temp is hot, it shuts off when you open the driver's door (hope for software update to solve this problem), but the vehicle was cooled down. I can live with this.

88 in NJ today and the AC was on auto, recirculating and it was terrible in the car. My 14 overland could not even keep up with getting it down to 79. My 2011 was a refrigerator compared to this. Did they change the compressor on the new 14? Ugh!

Re: 2014 Grand Cherokee Air Conditioning Problem

I don't think my recirc works in auto. When I press the recirc button, and it lights, the auto light goes off. That's why my post says recirc with max/cool. 85 outside, and after a bit I turned the fan down, as it was getting pretty chilly.

It's been in the mid 80s this week with high humidity, the AC has functioned perfectly for me in the front with plenty of room to spare (I'm sure my AC will keep me cool in the height of summer, even with my previous comments to the opposite), but I'm sure if I had guests in the back they wouldn't be happy, methinks someone needs to come up with an aftermarket fan kit doe the rear vents that allows for decent airflow.

Sounds like a great idea.

My experience with AC has been great up front.. But kids have complained a few times during first few minutes of a trip.. After a few minutes back seems to compare to temp in front.

I hope if I set the auto AC to like 60 when I have rear passengers I won't have to listen to the complaining, but sadly I have vocal complainers normally, grrr - like the family member who said "that means there is more to break" when I showed off the JGC....

Re: 2014 Grand Cherokee Air Conditioning Problem

AC report from Phoenix, AZ on 2014 JGC Overland:

Just returned from 30 mile non-highway trip. Temps midday at 106 to 108 degrees with blistering sun.
After initial start-up from garage, ran A/C at MAX, fan speed at 6. After 4 mins, got too cold, so reduced to normal and fan at 4. Front cabin very comfortable and my
"test passenger" in rear seat, agreed.
The A/C, at least in this 2014, has so far worked very well in AZ temps that have reached triple digits in the last two weeks. In my case, better than than our other vehicle, a late model BMW 740.

So I'm going to try to answer my own question as I was able to observer something very interesting. We went on vacation to Hatteras in North Carolina for a week. Temp outside high 70s low 80s but VERY sunny and car becomes an oven when parked out in the sun. During that weather AC seems weak. It seems like the cabin is just not cold enough.

Fast forward a week ahead and I'm back home to 90+ weather. Jeeps seems like a freezer!!! While driving I have to bump up the temp as people are complaining that it is to cold.

BTW: I always use Auto mode in my Jeep just play around with temp settings.

I do think that software is trying to do something funky. Guessing that when it is not hot enough outside it is trying to reduce AC usage or running it less frequently. When it is very hot outside it probably runs it 100% of the time. Just wild guess ...

Re: 2014 Grand Cherokee Air Conditioning Problem

What I have found is that the temp coming out of the center outlets goes about as low as 46F degrees in max setting with fan speed on 4. Doesn't seem to matter if it's 90F or 70F degrees outside. I never checked the outlet temp in my 2012 Overland because it always felt cold, but I swear it put out colder air than this WK2.

Quite a difference from the days when R12 was used as the refrigerant and it would put out 33F degrees. Now that was nice and cold.

This is exactly what happened to me. 78 going to Delaware the dog was panting, all the way down the AC was on auto recric. The other day 90 the AC, same settings was working great....what gives!?

I leave mine on auto, but if the car is hot, I drop the temp down to 60 to get the initial chill and then bump it up to the temp I want to maintain and it works for the front seats. I don't know if this helps keep the back seats at a decent temperature...
