Hi There, I'm Clayso a certified master automobile technician with 30 years of automotive repair and diagnostic experience.

From your description most likely the wiper motor is at fault. Fairly simple circuit to check. With the key on and the wipers on low verify there is battery voltage on the brown/white wire at the wiper motor. If there's battery voltage and the wipers don't work the motor is at fault. If there is no power at the motor on low check the same brown/white wire at the switch. You can also swap the wiper relay with another like relay. I like using the horn relay so I can easily check the relay after swapping. If the horn works after swapping relays the relay is good.

The washer is most likely the pump, sometime you can tap on the pump to get it going. You can also check this circuit with a voltmeter connected to the 2 terminals from the pump. Operate the washer switch and there should be battery voltage at the pump's connector.

I hope this information is helpful. If you have any questions let me know. You can reply back to me through this thread at any time.
