If your car's AC blows hot air for too long after sitting in direct sun in Ann Arbor, it may indicate low refrigerant, poor air distribution, or an HVAC blend door issue that prevents cool air from reaching the cabin quickly.
- Customer reported symptoms: “AC blows hot air,” “only hot air from vents,” “no cold air after sitting in the sun.”
- Local conditions: Parking on exposed campus or downtown lots heats the cabin quickly, so any weakness in the AC system stands out once you start driving.
- Possible causes: Low refrigerant, failing compressor, stuck blend doors, or weak blower not moving air through the evaporator fast enough.
- Repair: A full system inspection, including AC system pressure tests, temperature checks, and control function testing.
