I know there's some sort of TSB or recall for brake lines rattling against the firewall or something, not sure about suction lines though.
Obnoxious vibrating!
I just bought a used 2013 LTZ through a private sale. The seller told us the a/c needed to be recharged, as it was only blowing warm air. We still purchased it knowing it would likely need a compressor... which it did.
We replaced the compressor with an original GM part. Now, there is a horrendous vibrating sound heard only inside the car (or outside of you listen verrrrry carefully) when revving the car or when the a/c is on. We fiddled with a few things and found that the suction line (larger line entering fire wall) is what is vibrating against the wall and causing the sound. If it is manually pulled away, the sound is gone.
I have tried a couple different "padding" there today. It helps a little, but not much. Is there anything I can do to rid this sound?!

I checked again today, and it is definitely the ac lines. I held the line in many spots between the compressor and the fire wall, and all stopped the sound. I watched the compressor carefully and did not notice it shaking, but the lines coming out are definitely vibrating quite hard.
Makes me wonder if there is debris from the old compressor failing in the AC lines or expansion valve or something. Or a broken mount for that line somewhere?
I am having the system vacuumed tomorrow. I have never heard the car with working a/c before now, but I have an Impala as well, and my grandmother drives the exact same car, so I feel I can confidently say I know it's an unusual sound. I will have the a/c guy check the mounts tomorrow and let you all know if we are successful.
Fingers crossed!

Yeah, I think a blown compressor usually calls for the whole system to get cleaned out - and maybe even other parts (accumulator?) replaced for just that reason.Makes me wonder if there is debris from the old compressor failing in the AC lines or expansion valve or something.
Where would I find an accumulator?Yeah, I think a blown compressor usually calls for the whole system to get cleaned out - and maybe even other parts (accumulator?) replaced for just that reason.Makes me wonder if there is debris from the old compressor failing in the AC lines or expansion valve or something.
Also called a receiver/dryer. Round metal canister connected near the AC lines. Unfortunately (fortunately?) I don't have my own Cruze here to look at.Where would I find an accumulator?
