One reason for the A/C clutch not engaging is low pressure in the system . It's not always the compressor , could be "who" doesn't send the signal to the clutch and "why"
I think is just one idler pulley and one tensioner .Check out the one that bounces .
I have some chatter and grinding noise too , the chatter comes from the hydraulic lifter , I can hear it better from inside , sometimes at the light while idling I think I drive a diesel car :) , also when the oil needs a change the chatter becomes louder . I have especially noticed after a couple of hot track days , then I changed the oil and everything calmed down .
