Yes, A/C is fully charged. I was able to run the A/C full blast for up to 45 minutes at a time on early mornings, but the minute I drove it, it would stop, that was the ongoing issue! 3-4 days ago, I did remove the spacer/washer in the clutch, and the A/C has not stopped once! Safe to say the issue was the clutch spacing...thanks for everyones help!

Pulled the A/C clutch out this afternoon and removed the only spacer/washer that was in there. So far so good, but since the ambient air temp has gone down some, i'll have to see if the new clutch clearance will fix this problem once and for all!

Just checked that gap clearance it is .027-.030mm. 2004 Subaru service manual quote "Compressor A: INSPECTION 1. MAGNETIC CLUTCH CLEARANCE Check the clearance of entire circumference around the drive plate and pulley. Standard: 0.45 - 0.15 mm (0.0177 - 0.0059 in)

2004 Outback Limited, purchased used in 2014 w/107,000 miles, currently with 135,000. A/C clutch started to fail in fall of 2015, and eventually froze. Replaced full A/C unit with a Used Unit Spring of 2016... What's been done: 1) Used a/c compressor unit installed. 2) Full evac of a/c system. 3) Leak test - passed (-25 atm held for 45 mins) 4) Refill with using 2oz red dye, 3oz oil & 17oz R134a. 5) installed New Expansion Valve. 6) Installed New Receiver Drier. System runs smoothly, clutch engaging, cold air blowing for the first 15-30 minutes, then it goes warm. If I turn a/c off for a few minutes and turn back on, will blow cold again for about 1 minute. This was happening when the outside air temp was in the 60's, below 80's (not sure if it's relevant?). When the outside air temp was 89degrees and the car was up to temp, a/c wouldn't blow, clutch wouldn't engage. I've swapped A/C and Blower relays, same results. A/C clutch gap @.027mm -.03mm. Pulled glove box out a week ago to check cabin air filter...pretty clean. Did not see any blockage nor icing in the area. If the A/C is able to run in the morning for as long as 45 min, there clearly is nothing wrong with it...Is there some kind of a/c temp/thermosensor that I missed? Ready to pull my hair out!!! Any help would be greatly appreciated - Mel
