Random hot air through vents.
 
I have a 2014 6.7 power stroke. Absolutely love my truck. One thing is bothering me though. As I live in CA, I usually drive with the climate control off and the windows down a bit. Every once in a while, with the climate control off, I will feel hot air coming out of the vents. Hot as if I have the heat turned all the way off. The way I get it to stop is by briefly turning the climate control on and then off. The hot air then stops coming out of the vents. I have mentioned it to the dealer and they said they haven't heard anything about it and to pay attention to what the truck is doing when it happens. There are no lights or anything abnormal about the truck when it happens other than the hot air. Anyone have suggestions on what I should check? Any help would be appreciated. It bothers me a lot when things aren't working they way they should.

Iíd just leave the climate control on with the temp turned down or adjusted so it is the same as outside temp. Just remember anytime you turn on the defrost by default it engages the ac as well. So, floor or vent setting is probably what you want

I usually have the temp in the cold position. The problem is that regardless of where the temp was left at, the air that comes out is hot no matter what.

This is with the system off? So turn it on. If the cold setting isnít cold enough put it on defrost/floor. That will turn the ac compressor on a bit.
