What causes the blower on a ford aerostar quit working when you accelerate?

probably because of a vacuum leak. Also, air conditioned Aerostars have an "Economy Circuit" where the air conditioner compressor is cut off (turned off) during hard acceleration to remove the "load" on the engine and therefore, save on gasoline. Whether this circuit is malfunctioning and causing the blower fan to quit as well, is difficult to guess. Logically, the blower fan does not put any load on the engine so I still think it is a vacuum leak. I would check all the vacuum hose connections, including the black plastic vacuum Tank located above the blower housing in the engine compartment. These are just suggestions and not neccesarily the solution.

What causes the blower on a 2001 Chevy Silverado to work on high but not on low?
the blower fan rheostat usually located in blower box is like a resistor that draws energy from the blower fan supply to slow it down and there is a high speed fan relay for the fastest speed. So your rheostat is not working
