What to Do When the Windshield Washer Spray is Weak?

[DiGabriel]

Solutions for weak windshield washer spray: 1. Determine whether the issue is on one side or both sides. If only one side is affected, it is usually caused by a clogged spray nozzle. There are two solutions: first, use a sewing needle, pin, or very thin steel wire to poke the nozzle; second, empty the remaining washer fluid, then use an air gun to blow into the clogged nozzle. 2. Check the motor and its wiring. Have one person operate the washer button inside the car while another listens for the sound of the washer motor under the hood. If the sound is very weak, the motor may be faulty. If there is no sound and the wiring is fine, the motor itself is likely the issue. 3. If the problem lies with the washer motor, first check if the filter screen is clogged. A clogged filter screen can be repaired by removing the hose connected to the spray nozzle, opening the washer fluid filler port, and using an air gun to blow through the hose. This will force water from the washer reservoir out through the filler port, carrying any debris stuck to the filter screen. If the issue is something else, the motor will need to be replaced.
