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.

I took my 2015 kia optima (4 cylinders, 20000k) for an oil change, they also recommended the cabin air filter, I was ok with the price so they did it for me. That same day my a/c was working perfectly fine. The next morning I turned my a/c on and I noticed that it was blowing hot all the time so I took it back to my mechanic, they told me that it wasn't anything that they did wrong that the problem was my a/c compressor clutch, it was locked up, that my clutch should kick on, spin and stop spinning multiple times when the a/c was turned on from the switch and stop spinning completely when is turned off from the same switch, when the engine was off they also told me that the clutch should be able to turn by hand and mine was totally impossible to turn like that. I'm not a mechanic and I have no idea if they are saying the truth. Can anybody help me please?

On long trips, the clutch works and A/C blows cold. On short in town trips, NO A/C!

When the A/C is on and I am shifting gears, as I let out of the clutch and accelerate, an awful high pitched squeaking noise comes from the A/C belt of the car. I am under the impression that it has to do with the compressor but am not yet certain. I've been advised that it could be other smaller problems. However, the compressor is the only one that fits all of my cars "symptoms." Having the A/C on also causes my engine to run harder and with much less power, as well as die if decelerating from a high speed by only pushing in the clutch and sometimes when slowly shifting gears.

Noise coming from A/C Compressor when A/C is on or when the Defrost is on, Defrost uses A/C compressor.
Noise coming from engine compartment when air conditioner is engaged.

This problem started just about the time my warranty expired, of course! Symtoms: 1. a/c takes long to get cold once car initially starts. 2. Only gets cold if engine is running at about 2000 rpms. 3. Compressor makes whining noise.

They replaced clutch hub in 2009 and its doing it again , but they dont hear it when i take it in , and say that it is just wear and tear .. But it makes same noise that it did before they replaced it .. its dumb blonde syndrome they have with me i guess .. They think i am being picky i'm sure .
