MIX (Floor/Defrost)
WARNING: This page is about a different car, the 1995 Ford Pickup, 1995 Ford F-Super Duty, 1995 Ford Cab & Chassis, and 1995 Ford Bronco. However, it is still accessible from the selected car via links, so may be relevant.
In MIX mode, outside air is allowed into system. Vacuum is not applied to outside/recirculation and panel/defrost vacuum motors. The floor/defrost vacuum motor has partial vacuum, allowing equal outlet airflow. Blower motor speed and temperature can be adjusted to desired settings.
