"Oh well, I will take care of that when the weather warms up" I said to myself. Bad call...
Now with a new belt installed I can only get AC if I manually apply voltage to the pump wires. Otherwise, the pump never engages. I have voltage to the monovalve no matter where the switches on the dash are set to.
Where should I go from here? I really don't want to replace that switch unit...

Usually the compressor won't engage if there is not enough pressure on the system. Jumping the wires is not usually a good idea, it cuts out to protect the compressor. Get yourself some pressure gauges and you can rule that out.
