Hey there, sorry your having problems. If the fuses are all fine then you likely just have a faulty washer pump motor. This pump is located on the bottom exterior of washer resevoir.
Since the column switch provides the ground the best way to test the pump is just remove it and apply power and ground to the pump terminals. When the pump does not activate then you know its a pump failure.
If you have further questions just let me know please. thanks.
