What is the difference between AC compressor with clutch and without clutch?

Clutchless means that the compressor no longer has an electromagnetic clutch. This means that the compressor is permanently driven via the pulley and works even if the air-conditioning system is switched off. However, in relation to this, the power is regulated down to a few percent.

How do I know if my AC compressor is clutchless?

Start the car and turn on the ac. Using the clt, raise the input level until you see three or four dots on the clt. This will open the solenoid on the rear of the compressor allowing refrigerant to enter the pump; you will then see some movement on your gauges.
