I am pleased to report that the repair is complete. After soldering the wires going to the Climate Control Head back together (picking up a couple of burns along the way from working in that tight space) I turned on the headlights and had full control over all of the settings. As I hit the road before dawn to get to work (enjoying the heat coming from my new heater core) I was thinking that the real reward of doing this work myself isn't the money I save, but the feeling I get when I'm doing my victory laps. Although saving money is great too. 
Thanks again to all of my advisors here.

Okay. I feel stupid.
I found the problem. During my initial inspection of the wiring going to the Climate Control head, everything checked out as it went into an electrical tape wrap. As I worked in that area, the gray and white wire pictured above must have worked its way out of the tape wrap, throwing up a red flag. I unwrapped the rest of the wire bundle to find the other end and saw that not only was that wire severed, but my ground wire was frayed to almost nothing, right next to the power feed which was also frayed--all in pretty much the same place making me think that they've been rubbing against something that was sawing them off. It could be that they got moved around during the stereo install in a way that finished them off, so now I feel bad about putting this on the installer.
So, thank you all for the time you spent thinking through this, going through the FSM, googling and etc. Tonight I'll get busy repairing the wires and this weekend I'll put my dash back together just in time for winter weather.
The good thing that came out of it is that I fixed my heater core and lighter, and cleaned the contacts on my Climate Control head, all while learning a lot along the way. Thanks again to everyone who helped and to the Corvette Forum itself for being there.
