Weak Airflow with Bad Smell from AC
The AC is not blowing cold air, has a bad smell, and airflow is weak. This combination suggests a clogged or dirty cabin air filter, a failing blower motor or resistor, or a contaminated evaporator core. The issue is constant, indicating a persistent blockage or component failure.
