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 Lever Operation
Temperature is controlled by a cable operated blend-air door in the plenum assembly. When the temperature control lever is in the "COOL" position, all air is directed around the heater core. When the temperature control lever is moved to the "WARM" position, all air is directed through the heater core. When the temperature control lever is between "COOL" and "WARM" positions, air is directed through and around the heater core.
