Sounds like the clutch on the front of the a/c compressor unless the actual a/c compressor is locking up and causing the belt to slap.
the clutch would make a rattle like noise.

Either the belt has stretched, or the tensioner is not keeping it tight.
Or it has oil on it.

Ac makes loud chatter on acceleration been throuhg


hi, there is a published technical service bulletin about this problem for these vehicles and the tahoes. the compressor sitting so low in the system, gets over-run by the liquid freon banging internally and actually locks up on and off during operation. this is the noise you are hearing. apparently there is a screen kit to install in the low side suction line to prevent this from happening, but GM also states the compressor needs to be replaced and the new compressors from GM at least, already have this modification done. So, i replace them when they come into my bay with the complaint you speak of, and the tensioner for the belt, likely the belt too. but it looks like you already know all about that. hope i could help.

90's buick (unsure of model) clicking noise


Have you checked to see if the tensioner pully bearing has frozen up? They have to be changed every now and then. The bearings can be replaced without replaceing the whole tensioner pully and spring assembly.

03 suburban ac problem


Put a new belt on it and spray the condenser coil in front of the radiator with a hose when it gets up to temp or the sound starts and see if it stops. Thats what I did today. Flapping/clacking stops for about 10 minutes until thing get hot again.A/C blowing cold air the entire time.

Same noise


Just change the compressor it is easier than changing the clutch if you do dont forget to change the reciever dryer and the orfice tube and have a evacuation done on it.

Serpentine belt slips off idler pulley


The A/C pully is supposed to spin freely until the AC is activated to run.. The cranshaft pully does not. Replace the tensioner pully. The belt has to fit in between the grooves on the pullys.
