you completely emptied the ac system and recharged it and used a vacuum pump? The pump you refer to you mean the ac compessor and its clutch operation? hissing from the compressor?

blew the compressor. metal chips everywhere. replaced and back on the road. I wish it was a less tedious and expensive problem but the car has 236,000 miles on it, i cant' complain over it's only breakdown so far.
