Hello,

I'm trying to find the source of a noise (whining noise) that seems to be coming from the compressor unit of my 2007 Honda Accord Ex coupe.

1)I replaced the o-rings inside of the power steering pump assembly and afterwards the noise did not go away.
2)The noise starts to build gradually upon starting the car. When the AC is turned on the noise seems to go away. As soon as the AC is turned off, the noise returns.
2)The noise seems to be coming from the compressor, however, I'm not completely sure.

Any help would be greatly appreciated.
