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.Google+

Kia Sportage Failure of AC Compressor Clutch
Kia Sportage Problem

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.

A/C just went out completely. A/C Clutch and Compressor.

First it blew cold air, then outside air, then back to cold air, then stopped all together...mechanic says it is the a/c clutch coil... I really liked my Kia at first, but it seems there is always something happening to it, the gear shift lock release broke, I can't get it out of gear now without a pen to push the button in and out, but since it was so hot this summer I am choosing to fix the a/c first...not to mention other little things that seem to break...I personally will never buy another Kia, and when asked by others I will not recommend it either.

air compressor clutch is rattling and making noise. of coarse my warranty just expired at 5 years. I think if this is an ongoing problem (from what I have read) the company should recall it and fix it. hopefully the clutch can be replaced without replacing the entire compressor. ive been a kia sportage owner since they first came out, never had a problem until I bought the 2008 but was treated very poorly at the dealer. it was kind of yeah yeah yeah what do you want to us to fix, at full cost to you....no more good word of mouth compliments from me.....

Ac clutch went at about 100,000 miles. I have to fix it, even though everyone I know who has same car is having the same problem!!!!!!
Same thing, a whining vibration when ac is on, even after a freon charge.

whining noise, took to mechanic and told me AC compressor needs to be replaced. Seems like a common problem in this vehicle!! not happy with the repair cost!! luckily he charging $500 instead of $900 the dealer wants.

The noise comes and goes and is very annoying. I had it checked out at the dealers and found that the a/c compressor has an internal fault and needs to be replaced.

this has been happening to my car since I bought it. Kia dealership told me it was normal.
