The AC is blowing out hot air when on the cold setting.
Hi, there are a few things that could be happening. The compressor for the A/C system may not be working properly due to the electronic clutch not engaging fully or the compressor not producing enough pressure for the system to work. There also may not be enough refrigerant in the system which usually means a leak has developed somewhere. Do not add more refrigerant as it will just leak out again. A certified technician, such as one from YourMechanic, would be able to pressure test the system for leaks and make sure the compressor is working properly in order to determine why your AC is not working.
