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