Okay, try connecting a temporary jumper wire from the light blue wire terminal to a good ground. With the key on, that should cause the motor to run on high speed.

Similarly, using temporary jumper wires to ground both the light blue & black wires should cause the motor to run on low speed. And temporarily jumpering the dark blue wire to ground should cause the solenoid in the washer pump mechanism to click (and engage the mechanism to start pumping if the motor is also running).

If it still doesn't work using the jumper wires (and you have power to the motor via the yellow wire) then the problem is something inside the motor itself. But if you can make it operate using the temporary jumper wires, that would point to a problem with the switch or wiring.
