Moving Right Along...
While I was waiting for further inspiration, I went ahead and shorted those two wires running to the dryer. To be safe, I used a 15A fuse to do the job. Lo and behold, the compressor kicked on, the vacuum pot opened, and I had air flow through the center vents.
I am assuming, baring further enlightenment, that the switch closes when there is sufficient pressure in the AC system, and in so doing, supplies voltage to the other lead going to (from?) the pessure switch.
I guess all I need is a recharge of the refrigerant, and to see where the leak (if there is one) is located. Correct?
