I can take a shot at the jumper as a final check though I could see the switch change states on my multimeter, both via continuity and voltage. I've used my cell phone to take Picts of the wire runs and they (fans and switch wires) all go to a bundle zip tied into a bundle attacked to the back of the fridge and can't really see the ends. Of course it is half way between the vents too.
