The mode to allow fresh air only to enter the passenger compartment is often referred to as economy or simply “ECON.” The temperature can be controlled using the temperature lever. This would allow some of the air to pass through the heater core on the way to the inside.
The position where the air enters the vehicle also is adjustable so it can be directed to the floor, dash or the defroster vents and often in combination of two or all three positions.
If air conditioning is wanted for cooling, then a button with a “snowflake” icon or the letters “AC” on it needs to be depressed to cause the A/C compressor to be engaged.
The air entering the cabin enters at the base of the windshield and first travels through a cabin filter where pollen and dirt are removed. The air then flows though the ducts to the interior.
Ask a knowledgeable salesperson to explain how this is achieved on the vehicle you are considering purchasing.
