Q: AC not working

asked by on

The air conditioner in my car is not working.

The most common cause for AC not working is a leak. Once the refrigerant pressure gets low enough, the system will not work. The vehicle has pressure sensors that keep the system from starting so that you do not damage the compressor. There are other things like a bad compressor clutch coil, burnt compressor clutch, or a bad relay that can also keep the ac from working. A technician, such as one from YourMechanic, should be able to help you diagnose your air conditioning issue.
