Tom, the Arduino website says the Nano has a pull up value of 100 megohms. I need to find a way to wipe and reset the processor to see if the pins go back to the original value.

That is interesting. Maybe the processor chip is an outlier, with an exceptionally high internal pull-up value. You could connect your own pull-up, like 22k ohms from +5 volts and the function switch, and see if that helps.
