Q: Air is not working in car

asked by on

The car air conditioner is not working.

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.
