Electric Mode Door Actuators

Electric mode door actuator positioning is controlled by BCM. Feedback signals are input to BCM for each electric mode door actuator position. When desired climate settings are selected at HVAC control panel, BCM processes selected climate setting information and positions mode doors accordingly. BCM positions airflow mode door, blend/temperature mode door, or recirculation mode door for selected climate settings. Position of mode doors in A/C-heater housing will control air source from either fresh outside air or recirculated air, temperature of airflow and routes airflow accordingly for desired air outlet mode selected at HVAC control panel.
