My 04 GT blows warm air out the vents even when the outside air is cool. I talked with Hoffman Ford and they said "that's they way it is". Does everyone have this problem? Is there a way to fix it?

Mine will do that. Considering where the vents pull the air from, it's pretty much expeced.

Unless you have the AC turned on, it will do that. Think about where its pulling that air from and how much heat is coming off of your motor.

Mr.~G

The air for the vents comes in from the grille between the hood and the windshield. It should be outside air temp (or close to). Some one was telling me that Ford suts off the heater (hot water flow) after it passes the heater core vs. before it gets there. So, the heater core gets warm therefore warming up the oustide air. I have not yet had the time to validate that. If it is so, I think it is an engineering snafu. I'm contemplating shunting the heater core to see if it makes a difference.

Mine is the same. Yes, you can bypass the heater core but im sure it wont make a difference.

Try it with the A/C on and if its still warm/hot then its the blend door in the core box under the dash. With the A/C off the air should be about the same as the outside air as it is pulled in through the cowl openings. Turning the **** all the way to the cold side ( blue ) closes the door so no heat should get through, good luck.

Mr.~G

With the A/C on the air is cold - Good. But having the A/C on robs power from the engine and burns more fuel.
When put on Vent (no A/C) and the button all the way to blue, the air is always several degrees warmer than outside air - say it's 72 outside (nice) its 82 at the vents (not nice).

All gaskets and vent doors in working order.
