WARNING: This page is about a different car, the 2005 Mercury Mountaineer and 2005 Ford Explorer. However, it is still accessible from the selected car via links, so may be relevant.
When OFF is selected:

- The defrost door vacuum control motor is at full vacuum and the panel door and floor door vacuum control motors are at no vacuum, closing off airflow to the passenger compartment outlets.
- 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.
- The A/C request switch is disabled.
- The blower motor is off.
- The auxiliary blower motor is disabled, if equipped.
