Before snipping the wires to the tstat so you can join the red and white from the wall end to end (which is the "two blues" AFAIK), I would try the whole thing with that 2a fuse jumpered. You cleaned it up, but just to confirm. You said that was the culprit last time.
Also I would undo that wire nut on the reds in case it is all corroded in there.
Then if that didn't help, I would snip the wires as mentioned before, leaving lots of wire out from the wall to connect your new (as might be needed) thermostat. (but also long wire from the tstat to rejoin with) If the furnace and AC run by the wires from the wall, then the tstat is not acting as a switch anymore.
