Hi,
I have a 2004 Impreza TS and when the AC is on I get this whining noise when stopped and idling while the car is in drive. It's relatively loud since you can hear it with windows closed and radio on. It comes and goes like it's associated with the compressor cycling. It seems to only occur over a narrow range of RPM's since if you put it in park (RPM's go up a bit) it does not do it.
Does anybody else have this or heard of it?
Thought I'd ask before I go to the dealer to have it checked.
Thanks,
