Found a thread over a Matthew's Volvo Site where someone suggested jumping the pressure sensor pigtail to keep the compressor running in order to suck in the coolant. You (Klaus) had actually suggested that too.

I did it, and the compressor started running. I was able to drain another 1 & 3/4 12oz can into the system and it started blowing cool air nicely. I restored the pressure switch and couldn't get the compressor going again until I pushed it with a broom stick. Then it sprang to life and ran for quite a while. I put the windows up and enjoyed the cool air pouring over me.

I had to "manually" start it twice this way, but both time it ran until I shut it off.

I'm guessing that the heat causes the clutch to move just far enough away to keep it from re-engaging when it gets hot...

So... gonna re-do the clip fix. All the clips were gone, so I'm going to use some adhesive this time and then give the car go in the AM.

I guess a combo of the two issues was killing the system effectively.
