***ALWAYS and I mean ALWAYS check for a broken or seized AC BELT TENSIONER wheel before you go giving alway tons of money to a pro for an easy fix. This is a very known issue with older GM trucks. It happened to my 2002 Suburban. GOOD LUCK!

@ innsac check the harmonic balancer if its wobbling, that the cause of your belt tensioner to make that noise when the compressor is activated to much vibration is happening at the time and so the tensioner is the weakest link so it will wobble and even break. I went through four of them already

So I too have the same issue but I believe its the compressor and here is why. My girlfriend bought it in the winter and wasn't sure if the AC worked or not. I tried charging it leaked out of the condenser so I cleaned the system and put it back together. It held vacuum fine but after charging it made that noise. I discharged it and it didn't. Charged it back up and it did it again.

The problem isn't the tensioner or belt. Its the oil inside the compressor. It gets sludged up and causes the compressor to drag. It has to be replaced with the updated compressor to fix the problem.

Open the hood and inspect the A/C compressor for damage and to see if the compressor is seized. Verify that the serpentine belt is not damaged or missing. If the A/C compressor is seized, proceed to step 5. 2.) Perform the A/C System Performance test. Refer to the Heating, Ventilation and Air Conditioning (HVAC) section of SI. Correct any performance concerns or refrigerant leaks that are found. 3.) Inspect the vehicle for other possible sources of A/C compressor noise or performance concerns. Refer to Corporate Bulletin Number 01-01-38-013 for more information. 4.) After all other possible sources of A/C compressor noise or performance concerns have been eliminated, only then should the A/C compressor be replaced. 5.) Remove the A/C compressor. Refer to the A/C Compressor Replacement procedure in the HVAC section of SI. 6.) Inspect the transmission cooler lines for damage due to contact from the serpentine belt.

Well sorry for getting back so late to everyone but the end result was the compressor that was causing the problems so I bout a new one off Craigslist for $80.00 ( it was brand new never installed huge deal lol). So I did another system flush. Installed the new compressor, charged it and now its doing just fine. Be sure before installing the compressor to make sure it has Pag76 compressor oil in it or you will be back to square one and destroy your a/c system. Also replace all the o-rings.

Update well i ruled out the compressor no issues installed a new one ran fine for two weeks started the problem all over again. Since there was not alot of information on this issue I decided to pay attention to the Harmonic Balancer I have notice some vibration from there little wobbling going on so i will be replacing the Balancer and so a video on it so hopefully this will solve the problem. on yes i did a complete A/C overhaul flush and all and still have the same results so we'll see.

Update, well come to find out the compressor is the issue that causing all these problems, so needless to say the compressor is causing the strain on the engine which in turn causes the tensioner to snap thanks to Scotty Kilmer for helping me with this issue.
