Well Im just about out of ideas for you.
Seems strange to get a heater error due to an air leak but I guess I would turn towards looking for that.
10.45 volts seems a little low but you have covered the basics. Since you are already under there compare the pin 1 of the other secondary O2 sensor to see if it is 10.45 also. I know you are laying in the mud and cold and you qualify for the tough guy award, I know that is NO FUN! You could try ohming out the other heater wire that goes back to the ECU to make sure that is connected. That is in the schematic I noted earlier.
That's about all I can think of for now sorry.
