What is a common cause of insufficient airflow through vehicle A/C vents?

Insufficient airflow through vehicle A/C vents is often caused by a clogged cabin air filter. The cabin air filter is responsible for trapping dust, pollen, and debris from the outside air before it enters the vehicle's ventilation system. When this filter becomes clogged, it restricts airflow, leading to reduced ventilation in the cabin area.

As the air struggles to pass through the obstructed filter, passengers may notice weak airflow from the vents, which can make the A/C system less effective in cooling the interior. Regular maintenance, including replacing or cleaning the cabin air filter, helps ensure optimal airflow and improves the overall efficiency of the vehicle's heating and air conditioning system.

While a low refrigerant charge, a faulty blower motor, and a damaged ducting system can also impact A/C performance, they typically manifest differently. A low refrigerant charge can lead to poor cooling rather than reduced airflow, a faulty blower motor may cause no air movement at all, and a damaged ducting system might result in leaks or incorrect airflow direction rather than the overall volume of air.
