No I don't have a stethoscope. I appreciate the offer, very nice. Thank you, but if be afraid of wasting your time if we could not get it to make the noise while you were helping. I went ahead and ordered a new AC Compressor. Couldn't pass up the deal for a new Delphi for $100.00. The current one has been on the car for close to 400K. Pretty sure it's the clutch/ bearings making the noise. Hope I'm right, but if not at least I'll know that part is new.
