See that white box I am smashing with a crowbar, which is behind the 
firewall?  That where the fresh air enters the HVAC system.  It is drawn 
from the high pressure zone at the rear of the hood/front edge of the 
windshield.  And it is, or should be, sealed off from the engine 
compartment.

This is the case with many if not most cars and trucks.
