The most common cause of an AC failure is low refrigerant. Though that is what I usually find, this vehicle also has a history of compressor and relay failures. I would typically start by checking the pressure in the system with a pressure gauge. If the pressure is low then I would add some refrigerant. If it is fine then an electrical diagnosis will need to be done. If you want to have this diagnosed, consider YourMechanic, as a certified mechanic can come to your home or office to determine the cause of your AC issue.
