The noise seems to come from the compressor , but I am sure that it isn't. I have replaced the compressor, the power steering pump, the tensioner idler and the noise still comes and goes. When I force the power steering pump with a screwdriver placed under it and raised, the sound practically goes away. Sometimes, it does go away , but aways returns, usually the same day

By the way, the a/c does not work, but i think that is a leak in the lines.
