WARNING: This page is about a different car, the 2004 Mercury Mountaineer and 2004 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
When PANEL/FLOOR is selected:
- The air inlet door vacuum control motor is at no vacuum, admitting only outside air into the passenger compartment.
- The panel door and floor door vacuum control motors are at full vacuum and the defrost door vacuum control motor is at no vacuum, directing airflow to the floor duct and the instrument panel A/C registers. A small amount of airflow from the defroster duct and side window demisters will be present.
- The heater control valve is at full vacuum when the temperature selection is in the full COOL position, preventing the flow of hot coolant to the heater core. Otherwise, blended air temperature is available.
- The A/C request switch will be enabled. The A/C compressor will operate and the indicator will be illuminated if the A/C request switch is selected and the outside temperature is above approximately 6°C (43°F).
- The blower motor is on.
- The auxiliary blower motor is enabled, if equipped.
