I stopped by an auto store to get some freon but noticed the clutch did not move/engage with the compressor was on, I did not want to waste $70 to find out even though the sales rep tip toed around the issue saying it may be broken, or "maybe" it needs the oil in the can to lubricate it.
I wasn't about to let him play with my money until I did some research. AC repair is new to me, what are the most common failures?
I see a blue sticker with an "S" name on the chassis indicating it was converted/replaced at some point.
