That is a cool sheet. The park is electronic so I would suspect that
let the smoke out. At least it is easy to test.

Imho, it's a mechanical switch, of the type that only parts rebuilders seem
able to find. :^( I have not had the pleasure of owning this model, but on
other vehicles that I have owned, the fix is a rebuilt wiper motor. Up here
in snow country people flip the blades into the wash position before leaving
a vehicle for the night. If your vehicle manufacturer was short sighted
enough not to include this feature, then three or four replacement wiper
motors will convince almost anybody, even women, to remember to let the
wipers park before shutting off the vehicle.
