It's more likely a short rather than a quirk. I would be looking at the multifunction switch, and the wiring from there to the wiper motor.

One of our imports (a Honda) had windshield wipers that would turn on when it started to rain. This was definitely a short in the wiring, but I found it amusing and saw it as a plus. Unfortunately the dozens of other major problems with the car were NOT so amusing!!

We have owned three Explorers since 1995, and found all three to be absolutely flawless.
