Well, the fix was not long term. The foam was too soft and as it compressed, the noise came back. I have some 1" backer rod and I used it instead of the foam. It helped for a few weeks, but it has now compressed and the noise is back. Anything to look for regarding the compressor? The front a/c changes sound very little when the compressor comes on, but there is a big difference with the rear a/c. Can compressors be out of balance? I'm going to take the cover off again to see if I missed something.
FYI, both a/c's were replaced last winter under warranty.
