I have a 1997 Escort, the heater - A/C does not blow air, it does sometimes. The fuses look OK any hints where to start looking?

If you can hear the fan turning, then check the air duct valves under the dash. I believe they are vacuum operated on those.

You should be able to hear the fan running. (you dont have to have the car running to check this. At highway speed you should get air flow (not in MAX settings) with fan off or broke.

I can hear the swish of the vacuum and I do not hear the blower motot running again. I think the vacuum portion is working OK.

Could be the switch, the motor, or the blower resistor (or the wiring/plugs in between). If the blower motor is easy to get to unplug it and apply 12V to check it. If it works on high speed only, it's probably the resistor.
