Q: Air conditioner blows warm air

asked by on

The air conditioner blows warm air.

There are many reasons for poor AC performance, from low refrigerant, to a failed compressor. I suggest you have an AC performance test performed on your vehicle to determine the cause. This test involves hooking up gauges to the A/C system, and using the gauge readings to diagnose the lack of AC. A trained technician, such as one from YourMechanic, can inspect your AC system, and conduct this test for you.
