Weak AC Airflow with Bad Odor
The AC system is blowing weak air and emitting a bad smell, likely due to a clogged cabin air filter or debris in the evaporator case. This reduces cooling efficiency and air quality.
Diagnosis Details
Possible Causes
Clogged cabin air filter restricting airflow and trapping moisture/mold causing odor
Mold or mildew buildup on the evaporator coil due to lack of drainage or infrequent use
