Common Car Air Vent Problems
Several issues can affect your car’s air vents, ranging from simple blockages to more complex mechanical failures. Identifying the root cause is the first step towards a successful repair.
Weak Airflow
Weak airflow from your vents can be caused by a clogged cabin air filter, a malfunctioning blower motor, or blocked air ducts.
Incorrect Air Direction
If the air isn’t blowing in the desired direction, the problem likely lies with a broken blend door actuator or a damaged vent control.
Strange Noises
Unusual noises emanating from the vents, such as clicking, rattling, or whistling, can indicate a loose or broken component within the vent assembly or ductwork.
