Air conditioner

I have a 2002 Chevy Venture minivan 3.4L with 55,000 miles. The air conditioner is blowing warm air. I checked the compresser and the clutch is running. The system was low in refrigerant so I charged it up to 37 psi. The chart on the refrigerant can said the normal pressure was from 25-45 psi. The air conditioner worked great for about a day but now it is blowing warm air again. I checked the pressure and it is down to 30 psi. There is obviously a leak. The refrigerant I added says is has stop leak in it but this did not seem to stop the leak. Should I charge the system again and if I do will it just leak out again? Please help! Thank you.

Do you have oil on the compressor clutch pully or the serpentine belt? If so then there is a seal behind the compressor pully that is leaking. The kit is $45.00 and clutch tool $30.00 and you have to take cooling fans out to get a/c compressor out. There is a c clip that is in front of the seal remove it split the compressor push the seal out remove green outside seal 'o' ring
that is on the outer of seal[ can't see it till you get seal out] reverse order to reassemble. Mine was leaking and only way I found it was the compressor oil
