Why is there still airflow when the Elantra's internal circulation is turned on?

The reason why there is still airflow when the Elantra's internal circulation is turned on is related to the cabin ventilation system. Switching to external circulation can resolve this issue. Here's an explanation of internal and external circulation: External circulation introduces fresh air, while internal circulation blocks out polluted air. External circulation mode uses a fan to draw outside air into the cabin, creating airflow between the exterior and interior. The air from the fan comes from outside, so even when the fan is off, moving air will still enter the cabin to replenish fresh air. Sometimes you may feel airflow even with the fan off because external circulation is activated. Usage guidelines: Use internal circulation in heavy traffic and external circulation on highways. The use of internal/external circulation should be coordinated with air conditioning or heating. External circulation allows you to breathe fresh outside air. During long highway drives when cabin air becomes stale and uncomfortable with windows closed, activating external circulation brings in fresh air. If winter heating feels too warm, you can turn off the fan and activate external circulation to maintain cabin temperature while getting fresh air for improved comfort.
