Why is my car AC not cold enough on hot, humid Ann Arbor days?

When your German auto A/C blows cool but not truly cold on hot, humid Ann Arbor days, the A/C system may be slightly low on refrigerant, have a weak or defective compressor, or suffer from restricted airflow due to a dirty condenser or cabin filter, or have a radiator fan problem.

• Customer reported symptoms: A/C not cold enough; blows cool but not cold; takes too long to cool; A/C is poor in humidity.
• Michigan humidity: High humidity forces your car's A/C system to remove more moisture, which exposes marginal components and a low refrigerant charge.
• Common causes: Minor refrigerant leaks, worn A/C compressors, dirty condensers, weak blower motors, or a clogged cabin filter that reduces air volume through the evaporator.
• Solution: A performance test that measures vent temperature, A/C system pressures, and airflow is the best way to determine whether you need repairs or simply an A/C recharge.
