Cold air without turning on compressor?

[Nathan4066]

Base model 2015 Genesis.

I have noticed since I bought the car a month ago that the air seems to be pretty cold when I have the AC off, the Auto off, the fan on, and have it set to bring in fresh air instead of recirculate. This weekend I took a road trip and never turned on the AC once, even when it was 88 degrees outside the air remained cold. I even have a black model with black interior. Is something malfunctioning and my AC is actually on when it says it is not, or does the Genesis have the ability to cool air through some other means?

The climate control will override your desire to have the AC compressor off. Depending on the interior temp and humidity, combined with outside temp and humidity, it will choose to kick on the compressor to prevent what the Kroeans think will be fogging up of the windows.

Just to make sure you are setting the control to turn off the compressor. You have it set to auto, then push the AC button. Then when it is lit, you push the AC button again until it goes off. On the first generation Genny, If at the top of the LCD display you see the word "auto" and the defrost symbol flashing, the AC compressor is not off. It thinks it needs to keep it running. You can leave it in that setting, and at some point it will kill the compressor with the right outside and inside humidity conditions. Typically cold and dry, or warm and dry daytime conditions it will kill the AC. The first gen Genny I have is a pain with this. The programming is bad, and no real way with the fan going and system in to override the compressor to off in all conditions. The 2015 I have also exhibits some of this nanny deal, but so far (this spring is first time since new warm) it works better.

My response may not help get you to the goal of having they system on, fans blowing air, and under all conditions, compressor off.

I have tried manual fan and air outlet settings with AC off on my 2012, it will still turn in the compressor when it thinks it should.

Lots of people went thru this routine when I bought my Sonata ten years ago. The "LX" model has the same controls.

Once you push the auto button - it is one major hassle to disable everything again.

Never use auto - unless that's what you really want

OK weird, I never touch the auto button, but even after you toggle the AUTO off and the AC off it can still be in auto mode? Crazy. I never touch auto but I do the remote start from my app with the AC on auto so I don't have to get in a hot car.

The mystery cold air that you are getting may be the air conditioner trying to defrost the window as I believe DRS said - something else to try and turn off if you can. I believe that is part of the "auto profile" that comes on when you hit the auto button.

Yes... In a way. And my 2015 does the same thing. When it senses certain interior and exterior conditions, it turns on the compressor. If driving on a dark damp night, the compressor will kick in, even with the roof open.. When o am able to get it off, then it's condenser sends humid air out to compound the potential window fogging.

I was driving in the rain and turned the compressor off a few blocks from home like I usually do to keep the mold smell from developing, and my windows had fogged up nicely before I got to the garage. I think I had pressed the Auto button, then the A/C button twice, once to turn the compressor on and once to turn it off.

The difference between the Genesis and other cars I've owned is when you turn the compressor off the air coming out of the vents doesn't get hot, but to about ambient temperature. Maybe it's running at a low compression so that you don't get hot, humid air blowing on you, just cooler, humid air.
