AC vibration

I recently had a new AC compressor installed; the thing vibrates the whole car at idle. I thought with some miles it might break-in, but I've put about 3000 miles with no change. Before I take it back to the shop, perhaps one of you AC gurus could give me some idea what's going on. Thanks.

Re: AC vibration (Curveit)

Did you put the oil in it before installing?

An AC shop did the work; good history on them, so surely they did. I want some info to back me up when I take it back. Buzzes the whole car around 800-1100 RPM.

Had the same problem when I went to headers and they forgot to put the brackets back on.

Re: AC vibration (Curveit)

My '86 does it too, and I put two more compressors on to try and fix it. I also disassembled the brackets for the accessory drive so I could see and check everything, still no luck. I gave up on the problem for now, I have brackets for the '88 and up Nippondenso compressor in storage, so when I do my motor rebuild I might change over to the newer style. After looking at bothsetups more closely, it looks like it won't be easy though. :rolleyes:
