The clutch isnt engaging on my A/C. There is juice to the canister thingy on the right inner fender. What is that thing? I've been told it may be a pressure switch? Im guessing there is no refrigerant left. I dont want that gawdy newer compressor, so I'm going to go with a restoration, probably this winter. Im just wondering what is wrong with that switch-thingy, and why it isnt engaging. Thanks!
