Weak A/C Airflow with Bad Odor
The A/C system is blowing weakly and has a foul smell, likely due to a clogged or dirty cabin air filter, or a buildup of mold/bacteria on the evaporator coil. This reduces airflow and causes odors.
Diagnosis Details
Possible Causes
Clogged cabin air filter restricting airflow and trapping moisture/debris, leading to odor.
Mold or mildew growth on the evaporator coil due to moisture, causing bad smell and reduced airflow.
Blower motor resistor or fan failure causing weak airflow.
