The AC compressor is the heart of a vehicle’s air conditioning system.
It is responsible for pressurizing and keeping the refrigerant flowing.
Signs that your car's AC compressor starts to fail:
1. AC no longer blowing as cold as it must.
2. Loud noise when your AC is switched on.
3. Compressor clutch is not moving. The clutch can seize or break so
compressor is permanently active or not running at all.
