    Electric fan options, what?s the difference in the settings inside HPT?

    2002 411 PCM from a truck/suv. It has a no-fan option, of course, which I understand, but the other options I am not sure what they mean (what’s the difference in them)? The two I’m asking about are “Aux Fans” vs “2 Fans”.
