Thanks! That will help quite a bit. Here's another link that might help anyone else that finds themselves in this situation:

After chasing down all sorts of information regarding the a/c control system this afternoon, I've narrowed my problem down to the clutch. I've confirmed 14VDC all the way down to within 12" of the compressor, yet the clutch isn't engaging. I suspect that there is a fusible link located either on or closer to the compressor. Hopefully it's just a bad fusible link and not a toasted compressor or clutch. I have a bad feeling that "Black Death" might have finally paid my car a visit though.
