Temperature Control Knob
WARNING: This page is about a different car, the 2001 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
Temperature control knob uses a cable to control temperature blend door. Temperature blend door motor provides a variable number of temperature blend door positions. When temperature control knob is in cool position, temperature blend door shuts off airflow to heater core. When knob is in warm position, air is directed through heater core. When knob is in intermediate positions, heated air is blended with cooler incoming air to achieve desired temperature.
