Default Hot air coming from vents?

Hi I'm new here and have a question. I have an 05 GT 5 speed and I've noticed that when driving I am getting warm to hot air coming out of my air vents, primarily out of the 2 center vents. It only does this when I have the air shut off. If I put the a/c on it blows cold and blows hot when I put the heat on. The temperature gauge reads normal as well. Is there anything I should be worried about?

Sounds like the normal fresh air from the outside.....coming past the rear of the hood into the vents.

Fresh air coming in is hot, that's all.

Trick I learned on the '05: The trick to close those fresh air vents when driving with the windows down is to simply turn the MAX AC on for a couple secs... just long enough to have cold air coming through then turn off the AC. Viola, no more hot air... atleast until you power off the car and get back in... Then it will reset for some strange reason.

Why does it have to be my first car? No other car I've owned has done this and I've owned my mustang since 08 and it just started doing this this past winter.

It's pretty normal. Every single car I've ever owned had this happen in one way or another. I had a friend with a 96 Z71 truck that blew hot air through the floor vents horribly, which he called his "free heat" lol. I honestly think it comes from aging seals or mechanisms on the blend doors, which would explain why max A/C would temporarily alleviate the problem (recirculation mode, blend door shut). You're doing better than my co-worker, his windshield freezes from the inside in the winter, and no combination of climate settings on the dash can fix it as long as the truck is moving - and it's a 2011 model lol.

It was sarcasm, lol.
Nuke is known to indulge in it since this past winter at least.

To stay on topic, check and see if your cabin air filter is OK or hasn't shifted.
That could be an issue, if not, the members already answered your question pretty much.

I am super **** about everything in my Mustang.
when the AC isn't on, i close the vents.
when the vents are closed they all must be perfectly horizontal.
in my honda civic, warm air comes in too. unless i switch the vents to circulate instead of outside air.
that is just like what another post said about switching to max AC for a second, then turn it off.
Max AC is recirculating the cabin air and closes the outside air vent.
