2013 sentra AC problem

[ecphotoman]

Over the past two months I've noticed an odorless steam/vapor coming from my AC vents. Its happened a few times and sometimes it takes a while, like 30 minutes for it to stop. My engine temp is fine and no radiator leaks anywhere. I'm stumped, I purchased my car from Carmax back in December. I took it in for warranty service and they say there isn't any leaks anywhere, but this doesn't seem normal. I've owned several different cars before and I've never seen steam come out of the AC and been told it's normal.

Anyone had this issue?
Thanks.

It could be humidity or heater core issue. Does it smell like coolant?

There is no odor to it at all, it only comes out of the center vents and dissipates really quickly.

Just temperature conditions causing issue.

Sounds like humidity, happens here in Florida all the time to all the car's I've owned. Looks like a fog thing coming out of the vents and then disappears after a short time. It's no big deal. Try starting the car with the AC recirculation on, that works for me.
