“Why Is the AC In My Vehicle Not Cold?” If your vehicle is AC is not blowing Cold Air, you probably are experiencing a cooling fan problem, a clogged filter, or even radiator trouble, but the most common is a refrigerant leak. If the AC system has a refrigerant leak, it means the refrigerant fluid instantly evaporates when it meets the air. “Why is the AC in my Vehicle Blowing Hot Air?” The AC in your vehicle may be blowing hot air due to various issues. Again, a refrigerant leak is the most common cause, as it prevents the system from producing cold air, or a malfunctioning compressor, which pressurizes and circulates the refrigerant, also resulting in hot air.
