2007 Mazda 3 Five Speed
Had my AC Compressor replaced last year. Now when i turn on the AC while parked or
idle at the stop light I hear a strange scratching/clicking sound. If I rev the engine above
1500 rpm it goes away. As long as I am driving there is no noise could it be a pulley
Its the clutch getting stuck. Try checking the refrigerant if its low add some oil and conditioner.
