Hi all,

 

So I replaced my AC compressor clutch and coil about four months ago. The AC works great and blasts cold air. However, ever since I did the maintenance, I've been getting a grinding sound coming from the pulley whenever the AC is on. You can view a video of it

 

Any clue what this is? I took it apart and put it back together again...made sure all of the clips were in the right place. The gap is correct and there is no sound when the AC is not engaged (see the video).

 

Thanks all!

That was some b/s I just went through clicking on your link.

Wtf ?

It's just a YouTube link. Shouldn't be any b/s.

 

AC compressor be shot.

Right but it caused my phone internet to start doing the boogaloo. My apologies if it's my phone.

You might have some malware on your phone. It went straight to YouTube for me. No boogaloo.

GeneralDisorder - you sound pretty confident about that. Are you sure? Is it worth having someone drain it and refill it?

Well if it blows cold it's not low on refrigerant - which can cause noises due to the lack of oil circulation because the oil dissolves into the refrigerant and is moved around the system by it. This also indicates no clutch slip.

 

And if it stops when the compressor stops then it's not the clutch bearing.

 

So the compressor is on it's way out.

 

There really isn't much else to it unfortunately.

Ok. Thanks for the explanation. Guess I will just keep using it until it goes.

Not really the best idea as that will just foul the oil in the system and pump metal shrapnel through the condenser and possibly plug up the receiver/drier and expansion valve creating a more expensive repair. I would unplug it till you can get a compressor for it.

Agree, most likely the compressor is going bad. Also, agree on not using the A/C until compressor is replaced. Maybe you can score one from a wrecking yard. Buying a new one is expensive.
