Bi-Level

Bi-Level:

When Bi-Level mode is selected, air enters the module and passes through the evaporator core. Depending on temperature knob position, some air may pass through the heater core. This air will mix with the cooler air and then he discharged through the instrument panel and heater outlets.

Air flow design characteristics of the module will divert most of this tempered air out of the instrument panel outlets, with the air from the heater outlet being slightly warmer.
