Inconsistent Airflow

This could mean that one side of your car feels warmer or cooler than usual while another area remains at a constant temperature. You may also hear strange noises under the dashboard when adjusting the temperature settings. If these symptoms persist over time, they can significantly impact your driving experience and make staying comfortable on long trips more difficult.
