AC York Compressor Clutch Acting Up!!!

[Kneale Brownson]

If it blows cold when operating, you probably just need a new clutch.  
I've had a clutch go bad on a 200q20v compressor that, after 
replacement, the compressor returned to "normal" operations--at least 
for a while. Got maybe one more season out of it. I think it's kind of 
like the clutch MC/SC.  If you need to replace the MC, you probably also 
need a new slave.

From the get-go, I have to tap in the AC clutch in order for it to engage.
