another wiper motor / switch question

The knob on the switch doesn’t have 3 positions, it has 2 and then you can rotate it more or less.

I can’t tell if the motor has 2 speeds without removing it from the car as it just doesn’t start up.

Regarding the pump near the dimmer switch, there was nothing on my car. But i can push on the wiper switch and the brown wire coming from it was going to the washer pump on the original harness.
