Odd A/C noises! Concerning?
2002 WRX, on its second A/C compressor seal (I rebuilt the existing compressor, rather than replaced it).
Two issues:
On the first time that the compressor kicks on, I hear a metallic GZZZZK sound just as it spins up. It doesn't seem to do this after the A/C cycles on and off, as I am off and running, but I hear it a few seconds after I start in the morning.
Every 20 minutes or so (though it is really random, I might go a day without hearing it) I get this crazy slide-whistle sound - that is the only way I can describe it. Sometimes it goes up (low note to high note), other times it goes down! The A/C blows VERY cold (I only need it on "2" to cool the entire car) and cools down very fast when I start the car, so I have enough pressure to actually cool the car, but what the heck is causing this crazy sound?

Ugh, not looking forward to rebuilding that thing again... The clutch is still the factory original. Any ideas on the slide-whistle sound? I need to record it w/ my phone, no one believes what a crazy sound it is.
