1. What "should" be the difference between normal and Maximum, air flow wise?

2. Just test drove a Windstar and turned on the air and was blown to the back seat by the fan strength, my 93 aerostar doesn't even come close to that, assuming the fan motor is working correctly, and there is just that much difference between the two models, is it possible to put a Windstar fan motor in an Aerostar? WOW!!!

 

Hi,

normal position means outside air is coming in, max means the inside air is recirculated.
I take the fan strengh as "acceptable", I've seen better and worse.
