Mode Door Control

Mode Door Control

The servo motor for driving the mode door is installed on the side facing the driver's seat of the heater unit. Operating the mode selector switch sends a signal to the servo motor. In response to the signal, the motor makes a clockwise or counterclockwise rotation to drive the mode door through a link.
When DEF position (1) or DEF/HEAT position (2) is selected, the air conditioner switch automatically turns ON and the recirculation turns OFF.
