If your problem isn't solved by the reservoir check or by check to see if your jets are clogged, you can try one more thing.
Those "wires" you talked about earlier are actually washer fluid tubes. They run underneath the heat shielding and end at a stop-valve. Once the fluid passed through the stop-valve, it'll come out of the jets. I've had the stop-valve clog up on me so bad that it quit spraying fluid altogether. That may be your problem.
