Question on A/C growl/whine
 

I have a question for owners out there... I know that there is a TSB for the compressor growl/whine. My car's A/C compressor does make more noise than any other car I've owned, and is quite noticeable, but it is not too terribly loud. You can easily hear the difference with the A/C on vs off at pretty much any speed. Is that the noise covered by the TSB, or is mine just normal? It's done this since new if that matters. I would like to get it fixed if it is really a problem, but if it's normal I don't really want to bug my dealer for this. Thanks.

The noise is probably the mentioned TSB "whine".

To my knowledge (limited at times), the noise does not present a functional problem. But it does get louder. If you are under warranty, get it fixed and not worry about it. If not, discuss the issue with the Service Writer/Manager before committing to any work.

Generally, the parts need to be ordered before the work can be done.

So yours is basically quiet. I am under warranty and should have no issue with getting it covered based on past experience. I just wanted to make sure that my expectations were reasonable before bugging the dealer.

It sounds like the A/C growl problem.

I had the TSB work done last year. The A/C is quieter than it was before, but it still has a bit of a growl to it.

If you're still under warranty, get it done. If nothing else, you get your A/C system recharged for free.

As stated....

Yes the parts change, under the TSB, does reduce the while/growl considerably and noticeably. A SLIGHT noise, but not more than normal, will be heard after the repair.

MY OPINION.......it's worth the repair.

Guess what? I went from Honolulu to Las Vegas and not only do I get a growl but it smells like a wet rag. Parts on order to reserice the A/C but they are not R2 the compressor.:roll:

:eek: :steering: :scared: Musta been a heck of a ride... Any water on the passenger side floor? :rof:

:lol: Must have been tough finding gas stations! :roll:

Mine makes noise also
 

I took my 2006 LT2 in for the recall where they put the bubble rap in the head liner. I told them about the growl when I used the air in my car. They checked it out and found a leak in the front seal and replaced the compressor. It still growls just about as loud as it did before. Maybe it is something with those compressors.:confused:

Well, I finally asked the dealer about it when I took the car in for a dead blower motor. They agreed the compressor was too loud, and boy what a difference. I can't even hear the new one running. It's much much quieter. Anyone still in warranty with a noisy compressor, get it fixed. It's worth it.

AC now 'cool', not 'cold' after compressor was replaced
 

Hello...

My 2006 HHR with ~4200 miles had the noisy AC compressor noted in this discussion thread.

The dealer replaced the compressor the end of last week. The noise is now gone. However, the unit now blows cool air, not cold. I took it back today and the dealer said everything is "normal". He said it was fully charged and blowing ~40 degrees. If it is 40 degrees now, then it must have been 10 degrees below zero before. :-)

I did see in this post or another one, that someone mentioned the noisy compressor may have been related to the AC system being overcharged. So I don't know if this was the case on mine and I was just spoiled have really cold air before.

Has anyone else experienced this after having their compressor replaced?

Thank you,

David

If the system is overcharged with freon it will not cool as well and normally will not contribute to noise. Too much compressor oil will also cause insufficient cooling.

I had mine repaired in 2006 under the TSB. Never had a problem after that.
