The only item that should/could be in the air box, is the resistors that allows the fan speed to be changed.
Some debris could have gotten on to the resistor as most are open wire type.
I don't think that is what it was. I think whatever it was occured somewhere near where the AC was drawing the cabin air. I have everything opened up but cannot find any overt wire that fried. When you cycle the switch I can hear and feel a rely type click but it is behind the fuse box. it is not any of the relays on the fusebox.
