What does it do

Under normal driving, your engine creates vacuum. The Comanche uses vacuum to control many things, like the HVAC blend door, as well as the central axle disconnect. Under wide open throttle, the butterfly on the throttle body is open, reducing available vacuum. So think of it like a reservoir for vacuum pressure in times of high demand/low supply.
