a/c clutch stopped engaging. no power to green wire to clutch.

I would then do as GNRick said, and send a PM to Charlie F1.
I don't him personally, but I have read a lot of CharlieF1 threads and he is very knowledgeable with AC system.
Please post back of your finding as I would like to know the outcome. Thanks
 
This may help some in the future. It's how the compressor is wired on the car.
