air conditioner noise on 2003 Chevrolet Tahoe

When I first cut on the air conditioner in my car, it makes a very load grinding noise. I have had the compressor replaced twice before. Is that the problem and if it is, why do you suppose that it keeps going bad?

AC NOISE 03/TAHOE. THE SYMPTOM IS USUALLY RATTLING OR EXCESSIVE TENSIONER MOVMENT ON ACCELERATION. THE CONDITION MAY BE CAUSED BY AN A/C SYSTEM WITH LIQUED SLUGGING CAUSED BY A DEFORMED RETAINER GASKET.GM RECOMMENDS REPLACING THE A/C COMPRESSOR TO RECTIFY THE PROBLEM. A TEAC. SERVICE BUULITON TAB #01139B/C WAS ISSUED BY GM. THE TITLE WAS KW NOISE RATTLE INFO PART VIBRATION PERFORMANCE WARM COLD HVAC #PI01139C 5/7 04 THE #49276 TENSIONER HAS A LONG HISTORY OF FIELD PROBLEMS OR CONCERNS. GM SHOULD HAVE RECALLED AND FIXED THIS PROBLEM, MINE IS DOING IT AND TICKS ME OFF. GM SHOULD GIVE ME A NEW AC PUMP, WITH SO MANY PEOPLE HAVING THE SAME PROBLEM. LETS GET A RECALL GOING.

I agree this is BS. GM needs to do something about it.

I have a 2003 Silverado and have replaced the Tentioner pully (full assemply and both belts) As I reach 2000rpms I hear and knocking noise. I have trouble believing it's the compressor as I have Nice cold Air cranking through it and the A/c doesnt have to be on in order for this noise to accure. ANY suggestions? I will add Freon tonight and then ensure that the tentioner pully is tight not hitting anything. But I only have 74K mile on the truck and GM was more than happy to replace the Compressor for $966.00 I don;t have tha lay'in around PLEASE ANY SUGGESTION!!!!!

The AC will blow out cold air even if the compressor is going bad. You will hear a loud rattle noise under the hood during accelerations.
