The air is blowing hot air only.
There are many reasons why the AC would only blow hot air in your car. The most common would be a pressure switch or low refrigerant. Over time the refrigerant will leak out and once it is low enough it will no longer blow cold. The pressure switch on the other hand will fail and will not give the right signal to the electrical system which can keep the AC compressor from turning on. It may also be a blend or problem under the dash but that is not too common on this vehicle. I would typically install a pressure gauge set first to see if it is low. If the system is empty then there is a large leak that needs to be found. If it is low I would add some refrigerant to see if the system turns on. If not then further testing will need to be done of the electrical system. If you plan on having this fixed, consider using YourMechanic, as a certified mechanic can come to your home or office to diagnose your air conditioning issue.
