Some noise believed to be from compressor

[Rexter]

Anyone had change their compressor before care to advise.

Recently when I drive I notice some very little *woo* sound which is quite constant coming from engine bay, which can be heard from cabin of the car. When I switch off the aircon there was no more sound. Any expert can advise? Tia!

Listen with a screw driver on the compressor. You can then determine if the compressor is the cause.
