2002 Chevrolet Tahoe. One owner vehicle, bought new. Flutter/rattling sound when accelerating with air conditioner on. Does not rattle when compressor is off. Rear air stopped blowing cold. Mechanic states several people with the same problem. Replaced tensioner pulley. Belts. Still rattling/ loud. Now states compressor/condenser need replacing before seizes up. Mechanic states this is a know defect of this model, but not aware of recalls. This needs to be addressed since it seems to be a mechanical defect.

I just bought a truck from a used car dealer, who said nothing was wrong with the vehicle. There is a problem with the heating and cooling. When I turn off the A/C it still blows air out of the vents, and the truck needs U joints.

The fluttering/grinding noise actually began around August '06. I had to drive without ac with windows down to survive the heat. I asked a local auto repair station about the noise, since it was out of warranty, and he said he had worked on several Tahoe with the same problem. He said that the Chevrolet dealership knew about the problem because they instantly told him what had to be replaced. They told him the average repair bill for this issue would be approx $1500 at the dealership. Since then I have heard other Tahoe with the same noise, especially at stoplights when they accelerate. Not everyone can afford that kind of repair, and if chevorlet knows about this issue, why hasn't there been a recall. This is not the typical and routine wear like oil changes and tires.

Flutter/rattling compressor like sound when accelerating. Appears to be from A/C compressor. From my research, other owners have reported similar complaints. Dealer say this is not a equipment failure issue.
