Your 94 Aerostar is similar to my 93 explorer (uses same shop manual) The
heater duct is operated via a cable (like a bicycle gear ****ft cable). It
may have come off the lever or the duct door. DO you feel resistance and
hear flaps operating when you move it. No need to run the car to pump up
pneumatics, it is not.
You probably need to remove the main bezel of the dashboard to expose the
screws for the heater controls. I picked up a control panel in a pick and
pull last year for only $20. I needed the fan switch. These tend to burn
out the contacts so keep it as a spare if you get a new part. When the
fan
switch fails, it will either stay on full or off but nothing in between.
