The AC compressor pulley where the belt is connected to should turn. The face of the pulley is what does not turn unless you turn on the AC. The switch engages an electromagnet which sucks the face (AC clutch) in towards the compressor and then the spinning clutch, through friction causes the insides to spin and compress the refrigerant.
