ambient air pump: when is it turned on?

[Kneale Brownson]

I think the aspirator fan runs whenever the climate control system is 
on.  For sure, it runs when the requested temperature on the CC head is 
greater than the ambient outdoors temperature.  Once the temp setting on 
the CC head is reached, the aspirator fan MAY cycle (someone suggested this 
possibility in an earlier discussion wrt replacing the fans with a GM 
product to avoid the Audi $$$$$ pricing).
