Why is half my car blowing hot air?
A car A/C blowing hot air is often the result of a refrigerant leak. Refrigerant is a liquid that circulates through your car’s A/C system, expanding and contracting as it removes heat and humidity from the cabin. None of the other A/C components will function correctly without proper refrigerant levels.
