The A/C compressor is in charge of sending cool air into the vehicle's cabin. The component forces coolant and uses pressure to turn it from gas to liquid, and back into gas form.
A/C compressor functionThe AC system is important as it provides the vehicle with cool air, and without the circulation of the refrigerant cool air won't be distributed throughout the cabin. The A/C compressor is the central part of the system as the refrigerant pumps fluid throughout the hoses and pipes. Without the A/C system, it would be impossible to push out any cold air, only warm air would be generated.
As for the compressor, it is controlled by the belt that is linked to the vehicle's engine. The compressor is by the electromagnetic clutch so it adds resistance when in use. And when the clutch is engaged, the refrigerant travels to the closed-loop system of the vehicle.
Common issues with a bad A/C compressorA bad A/C compressor can lead to a lack of cooling and strange sounds.
