1. A vehicle, comprising:
a body;
a cabin that is defined by the body; and
an air delivery system, the air delivery system comprising:
a blower;
an air register positioned within the cabin;
ductwork that extends between the blower and the air register;
an intake module positioned upstream of the blower, the intake module comprising:
a housing that defines a cavity;
a first cabin air aperture defined by the housing;
a first cabin air door that is movable between an open position and a closed position relative to the first cabin air aperture;
an external air aperture defined by the housing; and
an external air door that is movable between an open position and a closed position relative to the external air aperture; and
a controller that adjusts a speed of the blower as a function of a speed of the vehicle, wherein the controller decreases the speed of the blower as the speed of the vehicle increases, and wherein the controller gradually decreases the speed of the blower as the speed of the vehicle increases such that the speed of the blower reaches a minimum speed that is greater than zero as the vehicle reaches a threshold speed, and wherein as the speed of the vehicle exceeds the threshold speed, a position of the external air door relative to the external air aperture is adjusted.
