Well, no wonder folks are having issues. Three people said turn on Auto.

Keep it out of damn Auto mode. Works Fine in Manual mode.

All Auto seems to do is control the Fan, which I rather do. Auto works poorly. It didn't take more that 30 seconds to realize Auto is stupid and I didn't even wait for it to cook or freeze me. It always wants to run fan at top speed. And I'll have none of that. But in Manual mode it works as well as any other car I've had, probably better.

I suspect most people that "Don't have a problem" also so happen to prefer Manual mode.

First of all if I pay for a feature it better work, your just taking the dealer approach by saying just don't use it. Second of all "manual mode" works even worse than auto mode in my wifes jeep, if you live through the cookout it provides it works decent, in manual mode it cooks you no matter what until you turn it down to 64 or lower, if you want it above 68 forget it, anything above 68 rounds up to 140 to jeep.
If you don't have the problem that's fine, but to say that it is the owners fault because they are using auto mode isn't exactly helpful.

The answer to the issue is not "dont use auto mode" auto mode has worked just fine in every other car i have owned. They need to fix it so that auto mode works as it should. If your fog lights were broken would the answer be just dont use your fog lights your headlights work just fine.

Re: Problem With 2014 Grand Cherokee Heater

For over 20 years (with the exception of an '07 Liberty) I bought a vehicle, set the temp at 68 and left it there until I got rid of the car. A few of those cars could blow warm air on your feet and cool air out of the dash at the same time. That was great on bright, sunny days in the winter.

While I have only had the overheating problem a couple of times, the Jeep system does not seem too sophisticated. Hopefully it is another programming issue that will be corrected.

I absolutely concur: your description matches my experience as well.

The problem is WORSE in "manual" mode, and it's a pointless distraction to opine that it is the user's fault the Jeep HVAC doesn't function appropriately.

One thing I find strange is the heat coming out of the dash vents. All my other cars when set to full auto sent heat out the floor vents and cool air through the dash. You had bilevel as an option.

mine comes out the floor for heat..(most of the time that is)

1) it does NOT work fine in manual... im either too hot or too cold and keep turning the fan up and down. In my 2005 scion Tc I can leave the fan on 2 and se the temp in the middle.. and leave it.
2) Auto... in every car I have owned (including the 2011 GC) worked perfectly. I dont think this is a solution. If they have the feature, it should work

The auto does suck as well but we are all having this issue in manual. The issue seems that there is no manual mode, the temp control behaves like auto would. Only car in 20 cars that does not have a manual mode.

Re: Problem With 2014 Grand Cherokee Heater

what a total PITA this is on top of piss poor engineering my jeep. And I agree with the folks that refuse to go by "don't use it" as a solution to a poor design.

I'm in Houston, so I feel bad for the guys in really cold climates. Hell, in 2 months, it'll be unbearably hot here, and I'll never take my a/c off of 60 for 6 months.

As long as that works, I'll wait for others to see if there is a fix.

Ok I finally decided to to post on Chryslers and. Jeeps official twitter page yesterday stating that people should not purchase these vehicles due hvac problems and jeeps unwillingness to help. We'll guess who already sent me 4 emails this morning asking for all the details and that they will put there top team on this problem. I am currently in discussion with a top corporate guy. FYI

Great work. Too bad Jeep wouldn't station an Engineer on this forum to track details on issues we see and report to build resolution.

Re: Problem With 2014 Grand Cherokee Heater

It would be great if this gets resolved. I really hope it is just some bad programming that can be fixed with a flash.

One reason I am so upset about this is that after surveying the market I decided that the JGC EcoDiesel was the only vehicle available that satisfied all the criteria I wanted. I could have bought almost any vehicle on the market. I don't want to lemon, I don't want compensation or a rebate, I just want it to work correctly because I don't want any other vehicle.

This problem just seems like such a trivial oversight, and it is compounded by the fact that the system is "too clever". If it just allowed me to actually control the temperature of the air coming from the vents then it wouldn't be so bad. As it stands, neither I nor my passengers can get comfortable. That makes people not want to ride in my Jeep.

Re: Problem With 2014 Grand Cherokee Heater

FWIW, I heard this morning from my Case Manager, who said she has been working with Chrysler's tech team and their climate control group.

They are aware of this problem, as it is also manifesting itself in their minivans in addition to the Grand Cherokee. She said the problem is both in the software and in the hardware, and she said they ordered a new head unit. Not sure what that means.

Will keep this thread posted on whether it works. No fix yet for the intermittent functioning of the keyless entry (not via the fob).
