Housing Assembly HVAC: Description and Operation
Air Delivery
The climate control unit controls the blower motor and supplies a 5 V DC reference voltage to the air mixture control motor.
The air mix and mode control motors each receive inputs from the control unit. The air mix motor regulates the mixture of cold and hot air by varying
the position of the heater-evaporator door. The mode control motor controls the direction and volume of outlet air. Use the MODE button to select the
vents the air flows from. Some air will flow from the dashboard corner vents in all modes. Each time you press the MODE button, the display shows the
mode selected. Press the button four times to see all the modes. Both the air mix control motor and mode control motor are grounded by the control unit.
The recirculation control motor receives battery voltage through fuse 3 when the ignition switch is ON (II). It regulates the position of the fresh / recirc
door, and is controlled by two position inputs from the control unit ("Recirc" and "Fresh").
