OK Jeff, bear with me. I idled the car, put it on max A/C, and connected those connectors. I heard a distinct whirring of the compressor. I assume this means it works?

So my next step is to have it checked for leaks I assume? Which switch may be bad that you referred to? Can I test it, or is it cheap enough that I can just pop another one in?

I am almost positive there is low, or no refrigerant in the system. At least the monovalve and pushbutton assembly seem to be OK, as well as the compressor.
