Air Distribution - Front Control

MODE SWITCH
Use the MODE switch in order to change the air delivery mode in the vehicle. The air flow direction will sequence through the following modes:
^ MAX A/C
^ A/C
^ BI-LEVEL
^ VENT
^ FLOOR
^ MIX-BLEND
^ FRONT DEFROST

MAX A/C
MAX A/C mode is only available on vehicles with the C60 option. When the driver selects the MAX A/C mode, the blower motor and A/C compressor clutch are activated. The recirculation door is activated, bring air from inside the vehicle for maximum cooling. Air is delivered out the instrument panel outlets with a small amount out the floor outlets.

A/C
A/C mode is only available on vehicles with the C60 option. When the driver selects the A/C mode, the blower motor and A/C compressor clutch are activated. Outside air is brought in to be cooled. Air is delivered out the instrument panel outlets with a small amount out the floor outlets.

VENT
When VENT is selected, air is delivered through the instrument panel outlets with a small amount of air delivered to the floor. Vacuum is applied to the mode actuator through the Brown vacuum line, and to the defrost actuator through the Red vacuum line. The mode actuator will retract, opening the Vent Door. The defroster actuator will retract, closing the Defroster Door and open the Heater Door through mechanical linkage.

BI-LEVEL
When Bi-Level is selected, air is delivered through the instrument panel outlets and to the floor outlets. Vacuum is applied to the mode actuator through the Brown and the Blue vacuum lines, and to the defrost actuator through the Red vacuum line. Applying vacuum to both sides of the mode actuator will hold the Vent Door stationary in the half open position. The defroster actuator will retract, closing the Defroster Door and open the Heater Door through mechanical linkage.

FLOOR
When Floor is selected, air is delivered to the floor outlets. Vacuum is applied to the mode actuator through the Blue vacuum line, and to the defrost actuator through the Red vacuum line. The mode actuator will retract, closing the Vent Door. The defroster actuator will retract, closing the Defroster Door and open the Heater Door through mechanical linkage.

MIX-BLEND
When Mix-Blend is selected, air is delivered to the windshield outlets and the floor outlets. Vacuum is applied to the mode actuator through the Blue vacuum line, and to the defrost actuator through the Red and the Yellow vacuum lines. The mode actuator will retract, closing the Vent Door. Applying vacuum to both sides of the defroster actuator will hold the Defroster Door stationary in the half open position. The Heater Door will also be held stationary in the half open position through mechanical linkage.

DEFROST
When Defrost is selected, air is delivered to the windshield outlets. Vacuum is applied to the mode actuator through the Blue vacuum line, and to the defrost actuator through the Yellow vacuum line. The mode actuator will retract, closing the Vent Door. The defroster actuator will retract, opening the Defroster Door and close the Heater Door through mechanical linkage.
