My 2000 Honda CRV with 200K miles has a repetitious knock only when idling with the AC on, apparently the compressor clutch engaging and disengaging. The AC is cooling OK. I’ve had the compressor, dryer, and expansion valve replaced - twice - and the same knock continues. Please advise?

Has the tensioner pulley ever been replaced? Its bearings could be making the noise with the extra stress of the compressor engaged.
