You may have a leak. At higher rpm's a/c compressor works better, that at idle, because it turns alot faster. Your level of R134 may be low in a/c system. Have garage check, how much R134 a you have in there.

Buy a Ford. That's what I had to do after the compressor locked up, broke the belt, at 61k miles. Customer No-Service wouldn't do anything even though the truck had been in the shop 5-6 times in 1.5 years for your same problem with no resolution. Cost me $700 and I told corporate I'd never buy another GM.

Your freon level is low, and not circulating on slow compressor speeds. Stop by any shop that has a sign stating they work on a/c and they can recharge it for you in a few minutes. Here where I live they charge about $20.00 labor plus a charge for the freon they put in, they sell it by the pound.

possibly low on freon. check for a/c oil stains/wet spots around all a/c connections. This will be where a freon leak would be.
Make sure cooling fans come on when the a/c is engaged.
Count how many times the clutch cycles in a minute. 4 to 7 is spec at 70 degrees F

No easy answer as it could be a lot of things from simple and cheap to difficult and expensive. The cooling agents used in air conditioing systems do not go bad or need to be replaced unless you have a leak in the system. Find a reputable independant mechannic to check it out.
