Donnie: Your new shop is looking GREAT! Too bad I live in Austin, Texas. Anyway, you were absolutely correct. I jumped the two wires at the low pressure switch and on came the compressor, however, no cool air. The window on the drier shows nothing, but I'm almost sure it needs R-12 freon. I installed R-12 many times in the early 80's and I have access to a good R-12 gauge set, but where am I to find the freon???

What is your opinion about the newer replacement freons for R-12 such as "Freeze 12"? Will they work in a 1988 Mercedes? What must I do before I install Freeze 12? Can I still buy R-12?

Again, Thanks! mscotta
