Open the hood. Turn the wipers on. Can you hear the noise coming the wiper motor, signaling that the motor is operational? Try this for all speeds.
If you hear the sound, the motor is good. If you do not, then check power coming into the wire harness of the wiper motor. Use a test light or digital voltmeter, positive to yellow and negative to black.
