A defective AC compressor clutch assembly can cause excessive noise or vibration when the air conditioning is on. Improved parts are available. Replacing the faulty clutch assembly does not necessitate replacement of the complete AC compressor or evacuation and recharging of the air conditioning system.

The A/C blows cold air for a little while, then begins blowing outside air. It sometimes goes back to cold for a little bit, but always goes back to blowing outside air. I took it to be looked at & was told by my mechanic that it was a known problem with my Kia model year (Sportage, 2006). The clutch on the air compressor goes bad & that a lot of dealerships will replace the compressor, but not the clutch. This does not correct the problem though. Kia (where I currently am) has been giving me a hard time about it & said that they don't keep the product in stock & that it will take several days to get the part in. I don't have time... I am moving in 36 hours & need my car fixed now!

Constant whine, getting worse. Dealer said it is the A/C "hub" (basically the A/C clutch assembly) Warrenty covers the compressor - but not the "hub". Can't buy the "hub" or clutch assembly from local parts stores - they only sell the entire compresser (clutch included)and dealer wants over $500 to just replace the A/C "hub". Can't afford to get this fixed.
Same thing, a whining vibration when ac is on, even after a freon charge.
