2006 XC90 A/C Compressor...solutions?

I tried recharging my A/C, same as I do every year. I used A/C pro (http://i.walmartimages.com/i/p/00/04/81 ... 00X500.jpg [1] ).

I attached it to low pressure port. The pressure gauge on the canister showed it steadily increasing from 10-25PSI, but right as it got into the green zone, I heard what I thought was my A/C line go. I checked all necessary parts with UV light/leak detector, but didn't see anything.

I tried recharging again a few weeks later and the same thing happened...rose from 10-25PSI and lost pressure. I turned car off and tried it again....same thing.

I think it's a compressor problem...

Does anyone have any ideas?

Put dye in system and find out where it leaks.

Was the fan on radiator running when you were doing this?
If your fan doesn't run to pull air across the condenser then the high pressure gets excessive and the pressure relief valve dumps refrigerant.
