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.
Control Panel Settings: Floor
With control lever in FLOOR position and interior temperature below temperature setting, blower operation is delayed by the thermal blower lock-out until engine coolant reaches about 120°F (49°C).
When blower turns on, outside air is directed through evaporator core to heater core. The blend door then directs airflow through heater core to floor ducts. Some air is directed to defroster ducts. The compressor does not operate in FLOOR mode.
As less heat is required to maintain interior temperature, blend door moves to direct only a portion of air from evaporator core to heater core.
