That's the bearing in the clutch on the compressor making the noise. If the
compressor is engaged then the bearing is not in use, that is, the shaft
inside that bearing is not turning with respect to the bearing. Not sure at
all if you could add some lube to the bearing, but running the AC will stop
the problem only when the pressure calls for the compressor to run.

> I drove my car 300 miles yesterday....stereo on and windows up. When I
finally pulled into my garage and opened the door (engine still running), I
heard a load screeching noise...I don't know how long it had been there but
it was not loud enough to drown out the stereo while driving and there were
no performance issues. I had been driving with no AC and decided to turn it
on in the garage (as a test) which caused the noise to go
away.....compressor kicked in just fine........turned it off....the horrible
> With the car cold today, I just went to start it and noise was not
there....AC could be switched on and off without any concerning sounds...it
wasn't silent mind you
> Anyone care to guess what is going on? How long before my AC clutch
completely packs it in? Can I drive this car long-distances worry-free
(with the AC on I suppose?)? What needs replacing? The car has about 165
000 miles on it.
