RE: Nothing but hot air.
I don't know sheeehyat about the heating systems on these cars, but I'm sure that the heater core has got to have some kind of vacuum operated control valve that either allows or cuts coolant to the core thereby giving you hot or cold air throw the Evaporator box (just like the good ol days). It's also possible that there is something amiss with this heater control valve or with the control switch that feeds it vacuum or possibly an electrical circuit if it is electrically operated instead. The problem could be anywhere from the heater core up to the control switch which is the temp **** ya'll are talkin about. Just my 2cents.

In these types of cars, the temperature lever operates a flapper door that blocks the heater core from the air flow when you want cold air and puts the heater core in the flow of the air when you want hot air.
It opens various amounts depending upon where the temperature lever/**** is set to.
In this type of car if you move the lever/**** real fast from end to end, you can hear the flapper door opening and closing as it hits the stops.
I'm not certain how the Mustang operates, but I have seen both types used on various different cars.
Follow the smaller hoses from the radiator, or wherever it feeds from to the firewall and see if there is a diverter valve in the hose.
If there is one, check to see that the vaccum line is connected or the wires if it is an electrically operated valve.

Yes, you are correct, either way aixtreme is gonna have to do some digging around and hunt for the control valve source, probably a vacuum hose but who knows.
Aixtreme,
You could spend hours digging around under there or take it to the dealership and pay them 85.00 for 1 hour to diagnose the problem.....then go fix it yourself if they want 800.00, an arm, a leg and your first born to fix it. Which is usually the case.

Some cars send coolant through the heater core all the time and have no diverter valve.
