Comfort Controls Air Conditioning with Electronic Controls Fan Knob The left knob regulates the amount of air coming into the vehicle. To turn the fan off, turn the knob to OFF. The fan must be on for the air conditioning compressor to operate. If the airflow seems very low when the fan knob is turned to the highest setting, regardless of the mode setting, your passenger compartment air filter (if equipped) may need to be replaced. See "Maintenance Schedule" and "Passenger Compartment Air Filter" in the Index. Temperature Knob The right knob changes the temperature of the air coming through the system. Turn this knob clockwise (toward red) for warmer air. Turn it counterclockwise (toward blue) for cooler air. With this system, you can control the heating, cooling and ventilation in your vehicle. The system works best if you keep your windows closed while using it. 3-2
