Steps

1. Open the hood and find the reservoir. Have someone operate the windshield fluid spray button inside the car while you listen for the pump to operate. It will hum.
   a. If no noise, check for a bad fuse.
   b. if fuse is good, the pump motor is likely bad. These new reservoirs often come with a pump. If you have a voltage meter, you can disconnect the wires to the reservoir and check for power when the spray button is pressed. If you don't have a meter, you will just have to replace the reservoir/pump and hope that it is not a wiring issue.
2. If the pump is working, you can unclog a nozzle with a needle.
3. If that doesn't work, pull the hose off the back side of the nozzle and press the windshield spray button. If no fluid comes out of the hose, then the pump is likely bad
4. If fluid comes out of the hose and the needle trick didn't work, you can use a pair of pliers to unclip the nozzle from the hood. You can soak the nozzle in vinegar to clear the nozzle or just replace it.
