Disclosed embodiments include airflow systems, vehicles, and controllers of airflow units. An illustrative airflow system of a vehicle includes an airflow inlet duct, an airflow intake duct, an air intake door, and an airflow unit. The airflow inlet duct is adapted to draw ambient air. The airflow intake duct is adapted to receive airflow from the airflow inlet duct. The air intake door is positioned therebetween. The airflow unit includes a controller configured to close the air intake door and seal off the air intake duct from the airflow inlet duct in response to receipt of at least one signal indicating at least one condition chosen from 1) a presence of water in the airflow inlet duct, 2) a hood of the vehicle being in an open condition, 3) a presence of rain received from a precipitation sensor, and 4) activation of a predetermined speed setting of a windshield wiper.
