Your AC is blowing warm air because while the fan is operating, something is shutting down the cooling mechanism. Causes include simple things like thermostat settings and poor air flow, but also could be issues that can spell big trouble, like electrical problems and refrigerant leaks.
Why is my AC running but not cooling in my car?
The most common causes of broken air conditioning are leaks or compressor issues. If your air is blowing cool but not cold, the problem could be a clogged filter, cooling fan problem, radiator trouble, or it could simply be that you need to recharge your AC.
If your AC is blowing hot air, the thermostat may have been accidentally set to “heat.” If this is the case, it’s easy to fix on your own. Simply flip the thermostat setting back to “cool” and see if the air conditioner begins to blow cool air again.
