Heater Done!

Got the control cables reattached and the inside of the car buttoned up. Fired up the engine and let it get good and warm and... nothing. No heat! I was dreading the idea of having to disassemble all of that stuff again, but then, suddenly, the air from the heater got hot! Only thing I can figure is there was an air bubble or something. Hopefully no need to disassemble again for a good long time. If I *do* need to take it back apart, we will be making some changes!
