Hey guys, just got my 2011 GC about 2 weeks ago and love it! I have the weirdest thing with the manual climate control happening and I wondered if this is normal with this system. Every time I start the Jeep the A/C is on automatically. Doesn't matter if it's 35 degrees outside or 75 degrees outside. I always push in the button to turn it off, but the next day when I get in the Jeep, same thing A/C is on. It really isn't that big of a deal, but I have the manual climate control and am not aware of any reason why the it would act that way. Any thoughts? Thanks!
I find that A/C comes on with the Recirc (to avoid excessive humidity buildup inside), but once it starts you can manually turn the A/C off and leave the Recirc on.

I keep mine in AUTO and 70 degrees and it seems to adjust itself accordingly. The A/C light seems to stay off for me unless I press it... I will check again tomorrow when I take it to get a TSB done on it...
Thanks for all the input. The recirc definitely isn't on and I've tried to see if it has anything to do with which vents are selected or something obscure like that. I'll definitely have to bring it to the dealer to check out, it must be problem with the HVAC, it's just bizarre. Thanks guys, I'll let you know how it goes in case someone else has any issues like this in the future.
mine (4 days old!) I noticed does this too. I assumed it was because I had the control on defrost... I thought it was usual for the system to use the A/C for defrost (drier air) At least that was the way in the 80s (when I last had a new vehicle
The system does turn on the A/C compressor when the defrost is running to help dehumidify the air, but it doesn't light up the A/C light on the contol panel when it's in defrost mode.
In AUTO, the climate control does a great job of keeping the temperature selected. Today it is warn and muggy in PA, and the A/C runs I'm AUTO with the light off. The light comes on only when I manually select it... When I'm not in AUTO, the settings stay where they are until I manually change them...
I have the same issue with the A/C being on when I start up and here's what the manual says:
"The air conditioning compressor operates in mix, defrost, or a blend of these modes, even if the air conditioning (a/c) button is not pressed. This dehumidifies the air to help dry the windshield. To improve fuel economy, use these modes only when necessary."
This makes sense for me because I usually leave the defrost or mix on (no recirc). I tested it by switching to the panel and when I restarted a few hours later, no a/c light. I personally would prefer the a/c compressor not default to being on during start up if I've left it in Mix mode. I'd rather select a/c then have to deselect it if this is in fact the way it is supposed to operate.
Thanks Dryfly, I'll have to try playing around with the vent modes again to see if it makes a difference. I guess it really isn't a big deal, just kinda strange that they would just program it to be on as a default in a non-automatic climate control system.
It sounds like the only difference between the manual system and the automatic system in regards to the A/C being on with the defroster is that the A/C light on the auto control panel doesn't light up while the light on the manual control panel does. The A/C is on with the defroster in both systems.
Well, I experimented with having the vents selected vs. mixed mode vs. floor only, and the A/C comes on with all. Probably will just bring it up with the dealer on my first oil change. No biggie. I appreciate all the input from you all!
