Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Temperature Control Selector
Temperature control selector regulates temperature of air entering passenger compartment through an electric motor mounted on blend-air door. In cold position, air by-passes heater core to provide maximum cooling. In hot position, the door routes all air through the heater core, providing hot air. By moving the temperature selector to any position between hot and cold, a mixture of hot and cold air is blended, creating warm air.
