I now have 14,000 miles on my 2014 Kia Sorento. While driving to visit relatives on Saturday (a two hour trip) the air conditioner was set on 69 degrees. About an hour an 15 minutes into the trip the air flow from the vents began to get weaker and weaker. I turned temperature down and blower speed to high and eventually the air flow completely stopped. You could hear the blower on high speed running but no air was coming from vents. I have video evidence of this if anyone would like for me to post video. Has anyone else had this problem? I have noticed the flow getting weaker on several occasions barely able to keep up with keeping cabin cool but had never had the airflow completely stop until Saturday.

unfortunately yes... what happens is that first the air coming to the car is being dried (A/C does it) and then warmed up. No matter what temperature is set it will always use A/C.
Now, there is a trick to turn logic off (logic is called automatic A/C when in defrost). However, I am not so familiar with auto setup. The way it works with manual systems - once the logic is off the A/C will illuminate when set to defrost. This allows you to chose - A/C is on or off. You manually turn it off and problem solved. No more compressor running no matter what temp you set.
If I find a moment I will look into manual, I suggest same to you
, and will try to find more info how to disable A/C.That's true, the A/C kicks on in (pretty much) all cars when defrost is selected to de-humidify the air. But, PLP... pulling the fuse? Dude, extreme.
But, there is no doubt that it is overly complicated to just have the fan going with no A/C or heater running in the KIA Sorento. If anything, the driver should be able to override any setting as long as it doesn't hurt the vehicle or compromise safety. And, getting outside air without A/C or heater should easily fall in that category.

Ok I was playing with the settings today to see what happens and it seems when in Auto modes, yes the A/C seems to run even if the temp is set higher like 80f and hot air is blowing out of the vents.
Oddly enough, most of the settings are in metric KM & Celsius for Canada, yet the temperature is in Fahrenheit. Weird...but I found that it can be manually changed by pressing two buttons at the same time - press Off and the Auto knob at the same time for 5 seconds.
I think I found out how to set this. It's called Defogging Logic and it uses A/C to dry the air (page 4|144). Press the Fan speed buttons to adjust the fan and Auto turns off. Then press the Mode button to select where you want the air to blow, setting it to Defrost. Then while holding the A/C button press the intake control 5 times rapidly within 3 seconds. It should blink to indicate defogging logic is disabled. Repeat to enable the defogging feature.
Cool...

A/C fuse only, dude.But, PLP... pulling the fuse? Dude, extreme.
Just to not allow the compressor to kick in.Yeah, I have done it in some "domestic" cars as I could not deactivate the logic.
Great. That is exactly same way you can deactivate logic in manual climate control systems. I did not know it would be exactly same procedure.
Yes, I found this out awhile ago that the compressor always runs with Climate Control on, even if the green A/C light is not lit. The "defrost logic" mode from the owners manual, will put it into manual mode, But, Defrost will not turn on the compressor, unless you do it manually. I've done this on my 2011 Sportage EX.

Maybe that is true on Sportage, but 2007 Optima, 2012 Sorento, 2007 Rondo, Elantra's (2004 XD, 2009 HD, and 2013 GD), 1997 Plymouth Neon, 2002 Dodge Intrepid, 2006 Dodge Durango - all of them would turn on compressor when in defrost.
Those are all cars I have owned or drove and Sportage is not there, so I will not argue.
Let me clarify, When set to "defrost logic mode" The A/C, compressor, & Defrost will not engage, unless you manually press the respective buttons.
Wow compatico! Thanks for finding that information in the manual and posting it. In my neck of the woods, there's no need to have the A/C running because our humidity is very low. I'm going to re-read that whole section to see what else I've missed.
What I don't understand is, why isn't a setting like this under the User's Settings? It's almost set up like a game cheat you have to punch in on your controller: A-A-B-X-X-Y... stupid.

I haven't read the paper manual...I downloaded the PDF from Kia and do searches for info when I need to figure something out. Much easier than flipping pages. Most of the stuff I figured out on my own, but that one issue needed clarification so I had to do some reading.
:lol:
I noticed that my 2014 Kia sorento ex while the heat is on, the rear vents blow cold air out while the front vents have warm air. Anyone else noticed this? I had the air conditioner problem as well.
I do. I looked in the manual and FYI they suggest closing the rear vents that blow at the face while using the heating system
Yeah I noticed this as well. Even after a 20-30 minute trip...still cold(ish) air.

now when you mentioned it - I am not quite sure, but I think they mentioned somewhere here that the upper vents are always cold... could it be?
look up in the manual or search here.
If I find a moment I might do it for you... only IF.
When we need heat, I make sure the fan is off until the engine temp is well past cold...if not at normal operational range. Then I turn on the fan and have the mode set to dual outputs...on the feet and out of the dash. It works well enough. And of course we turn on the seat bun warmers. We are toasty by the time we get to IHOP for breakfast.
But isn't that kind of ridiculous that we can't have hot air blowing out of those vents? Sometimes the passengers need a little hot air blowing on them if they've been in the cold for a while.

The rear passengers get hot air from vents under the front seats. The upper vents behind the front doors are just for A/C.
