Anyone else having this problem? (2005 GT) When I have the air vents on with no air cond, I get very warm air through them at all times, even when its not warm outside! Is there anyway that outside air can be vented through without it picking up so much heat from the engine compartment?

Just wondering if it has anything to do with the position of the thermostat (red/blue **** control. Try turning it to the blue (cold) side even though the heat or air is not on. Maybe that has something to do with it.

I have noticed this too - mostly only after the car has been running a while and it gets hot (which we know these Stangs DO run hot).
Closing the vents pretty much solves the problem for me.

It's happening to me as well. I've noticed that after turning on MAX A/C for about 5 seconds you can then switch back to the vents and turn the A/C off. The air is then much cooler and does not get as hot as is was before the A/C was briefly turned on.

Do you mean all '05s?
Because it definately doesn't happen in my current car. And as far as I can remember hasn't happened in any other car I've ever owned. So if you mean all '05s then yes maybe I don't know... but if you're referring to ALL cars I don't think so.

maybe its a ford thing then? the last 2 fords+my girlfriends last 2 fords did the same thing. its heat from the engine compartment. what it may be though it that you are only feeling it now because its getting hotter outside so even on a "cold" start, the car is already hot as heck from the sun with stagnant hot air. car starts moving, that hot air gets pushed out.

Yeah I have the same hot air problem. It makes it nice when there is a slight chill in the air because I can still drive with my windows down. Now that it is hot all the time it really doesn't make much of a difference. I'd rather find out why the darn air compressor clicks all the time.

There's a thread about heat and the catalytic converters, that may have ID'd your problem. The stock converters produce a lot of heat that is transferred to the passenger compartment. If it is heating up the air in the floorboards, it may be warming up the plenum chamber for the ac/heater?
The V8 owners seem to be having heat all the way across, and a V6 owner noted above that the heat is on one side (converter side?).
I can't do any testing yet, since my car is just a VIN and a build date at this point.
The thread starter installed aftermarket converters, and the heat problem in his floorboards disappeared.

My last 3 Mustangs have done this after the engine is at normal running temperature. All you can do is close the vents.

If you look at the way the outside air comes in you'll get your answer. The inlet vents are actually under the hood. A small bead of weatherstripping (molding) seals the under hood from the slots in the vent intakes. I took temp measurements of the metal between the engine compartment and the inlet vent box. 125F at idle in the summer. The flow is better into the car when moving because of the 'cowl induction' type effect at the bottom of the windshield in the center. That's where the air enters. Also the effort by Ford to seal the additional seams and spaces of the fresh air inlet vent is very poor . Lots of places for engine compartment air to enter..as I'm sure it does.
