Why Doesn't the Windshield Wiper Spray Water?
1 Answers
The main reasons why the windshield wiper does not spray water are as follows: 1. The nozzle or water pipe is clogged, which can be cleared manually. 2. There is a fault with the motor, water pump, fuse, or wiring. 3. The windshield washer fluid has run out. If the windshield washer fluid is empty, simply refill it. Below are the solutions for a windshield wiper that does not spray water: 1. If only one side of the wiper has a problem: (1) Use a sewing needle, pin, or very thin wire to poke through the clog. (2) First, spray out the remaining windshield washer fluid, then use an air gun to blow into the clogged nozzle. 2. If both sides have spraying issues, it may be due to low windshield washer fluid, a problem with the water pipe, filter screen, or motor. Follow these steps: (1) Check if the windshield washer fluid is low and refill it if necessary. (2) Inspect the water pipe for damage or loose connections. (3) Check the motor and its wiring. Have someone operate the spray button inside the car while another person opens the engine compartment to listen for any sound from the spray motor. If the sound is very weak, the motor may be faulty. If there is no sound and the wiring is fine, it is likely a motor issue. (4) If the problem lies with the spray motor itself, first check if the filter screen is clogged. A clogged filter screen can be repaired, such as by removing the water pipe connected to the nozzle, opening the windshield washer fluid filler port, and using an air gun to blow through the pipe. The water in the washer fluid reservoir will be blown out through the filler port, and any dirt on the filter screen will also be expelled. For other issues, it is best to consult a professional at a 4S shop.
