OK, so, despite warnings not to recharge the A/C in my 95 940t wagon, I did it anyway w/ the can of r134 that included a pressure gage. I was tired of 90º weather and I spent the 20 bucks, which has now leaked back out of the system and contributed to holes in the ozone as it hissed out from somewhere in / near the radiator...the system was equipped with a UV dye to easily detect leaks...but the hiss is coming from a place I can't see...it sounds like its coming from the center or passenger side of the radiator housing - about in front of where the low pressure tube from the A/C runs into it, but deeper inside. If it's not obvious, I don't know much about cars but this site has saved my life (and several hundred dollars!) What the heck is hissing in there and why? Thanks for any tips!
