My '01 Taurus has developed an hvac problem. When the AC is on for a while the air stops blowing out of the vents. I can here the blower doing its job but air will not blow from the AC vents or defrosters. This creates a really unsafe condition when the windshield is fogged up. If I play with the function knob by moving from funcion to function it will eventually start working again. I do not hear a vacuum leak, before or after. It sounds as if the heater door is closed and then opens again for some reason.
I don't even know where to start. Any Ideas?
Thanks
