2000 Ford Mustang Conv. Heater issue

Thomas2 · 01-16-2007, 02:40 PM

I have strange problem (or is it normal) with the heater on my Mustang. It blows cool air when turned on to blow hot air. When I turn it off and wait a minute or so and turn it back on it blows hot air for like 10sec then cool again.

Also it seems to blow hot air when I drive at least 30mph - when I am stuck in traffic I just get cold air from the heater.

What could be the problem?

More info: its a V6. Heater works when accelerating, after few seconds it blows hot air, then when one stops air starts to cool down.
