If your A/C cuts off after 10 minutes then works again after you switch off the car and back on again then it is likely to be a Kilma relay or loose connection. My take is a bad Kilma relay with a bad comparator circuit ( dry joints). You can try to jump the switch at the Recv/Drier to eliminate the high side pressure but I would doubt it is the issue.

When it does provide cool air, it was often inadequate - so when I found that both aux fans were out, I suspected the problem was there. The no-cooling situation (apparently caused by the compressor cutting out) has grown progessively worse.
I don't think it is the Klima as I replaced a bad one a couple years ago and cured the problems I was having then. That's not to say that the used one I replaced with isn't now bad itself, but I'm inclined to think it might be a problem elsewhere. (famous last words) The AC doesn't necessarily come back on if I turn the car off and then on again.
I will try jumping the reciever/drier to see what happens. I did hook up the gauges prior to the aux fan fix and both low and high sides were reading high - IIRC it something like 45/275. I will try it again though. Thanks for the input.
