Finally got a chance to look at this again.

I pulled the cowl cover and the wiper arms are connected. I moved the motor around a bit and the wiper arms pivots now move. The motor was seized.

However....even without a key in the ignition, the wiper motor comes on when I turn on the headlights. So the motor is getting power even without a key. I’ll trace back from the wiper motor and see which wire is hot. The wiper switch has no effect on anything.
