When your car A/C blows hot air, it usually means the system needs more than a quick button check. The cause could be simple, but proper diagnosis matters.
Common causes
- Low refrigerant from a leak
- Compressor not engaging
- Condenser or cooling fan issue
- Electrical fault or pressure sensor problem
- Blocked cabin filter or weak blower airflow
If the system is low, there is usually a reason. Topping it up without finding the leak may only work temporarily.
