What to Do When the Car Washer Nozzle Has Weak Water Spray?
2 Answers
Solutions for weak water spray from car washer nozzle: 1. Determine whether the issue is on one side or both sides. If it's on one side, it is usually caused by a clogged nozzle on that side. Solution: Use a sewing needle, pin, or very thin wire to poke the nozzle, spray out the remaining washer fluid, and then use an air gun to blow through the clogged nozzle. 2. Check the motor and its wiring. Have one person operate the washer button inside the car while another opens the engine compartment to listen for any sound from the washer motor. If there is sound, the motor may be faulty. If there is no sound, the motor itself is likely defective. Solution: First, check if the filter is clogged. A clogged filter can be repaired by removing the water hose connected to the nozzle, opening the washer fluid filler port, and using an air gun to blow through the hose. This will force the washer fluid out through the filler port and remove any debris stuck on the filter. If the motor is faulty, it must be replaced.
Last time my car's washer fluid spray was weak, I also encountered this situation. Later I found out the nozzle was clogged with car wax, and gently poking it with a paperclip cleared it. If that doesn't work, it might be that the hose was deformed or twisted by the high temperature in the engine compartment—squeeze the soft hose to check if it's flowing properly. For older cars, it's especially important to check the filter screen at the bottom of the washer fluid reservoir; if too much dirt accumulates, it becomes hard to draw water. If the washer pump sounds hoarse, it’s likely about to fail—a replacement aftermarket part costs around a hundred bucks. Before winter, remember to switch to antifreeze washer fluid; otherwise, freezing and expansion can ruin the entire water supply system. Don’t underestimate this issue—dry wiper blades can damage the glass.
