Default AC Compressor Squeaking

For the last couple days I have noticed when the AC is turned on I have some squeaking going on around the compressor somewhere. Belt has not been recently replaced so I have ruled that out as a cause. I figure its either the compressor or pulley...crossing my fingers its the pulley after seeing the cost of a new compressor....ugh

We have owned the vehicle for about three years with routine maintenance done meticulously. Vehicle is very well cared for with only 49k on her.

Anyone want to chime in with some thoughts and suggestion I would greatly appreciate it.

Thanks all!

Not exactly ruled out. New-ness has nothing to do with a belt squeaking or not. Is it a constant squeak while the engine is running or only when the a/c is turned on?

Still can be belt..... Actually it is more like the contact of the belt and the pulley. If the pulley is glazed, then even a new belt can squeak, especially if it's a cheap belt. An inexpensive way to figure out if it's a belt problem is to bet some belt dressing. If you get a change (even if not completely fixed) then go out and buy a gator back or other such high end belt.

Belt recently replaced?
Is the belt loose, check tension by pushing inward with your thumb between crank pulley and A/C compressor. Should be max play of your thumbnail. If loose - tighten.
If its ok, spray some silicon lubricant (WD40,CRC) on the belt and see if the squealing stops. If stops - the belt or pulley is bad.
If it doesnt stop squealing, get a screw driver and place on the A/C compressor (non moving part) put your ear to the handle and see if you can hear any grinding. Any loud noise is bad.
