What are windshield washer jets?
Windshield washer jets, also known as washer nozzles, are small components of the windshield washer system of a car. They spray washer fluid onto the glass in a thin, fan-like pattern when mounted on the hood or wiper arms near the windshield's base. When engaged, washer fluid pours from the reservoir through hoses and into the jets, clearing dirt, debris, and other contaminants from the wiper blades and ensuring a clear view for the driver.
Regular maintenance, including jet adjustment and cleaning, is critical to ensuring proper coverage and effective functioning, lowering the risk of reduced visibility and enhancing overall driving safety.
When should I adjust the windshield washer jets on my car?
If you observe any of the following problems, you should consider adjusting your car's windshield washer jets:
Uneven spray pattern: If the washer fluid is not dispersed uniformly across the windshield, certain areas may receive excessive fluid while others remain dirty. This can limit visibility, particularly in rainy or dirty situations.
Inadequate coverage: If there are spots on the windshield that don't get cleaned by the washer fluid, it can make it hard to see the road clearly. You might notice streaks or spots on the glass after using your washers.
Over- or under-spraying: If the washer fluid is sprayed too high or too low, it may end up on surfaces other than the windshield, such as the roof or the hood—or it may fall short of actually reaching the glass.
Clogged nozzles: If the washer jets get clogged with dirt or debris, the spray pattern may be affected, leading to insufficient cleaning.
If you've just replaced your windshield
, the washer jets might need to be adjusted to fit the shape and position of the new glass. It's usually a good idea to have your windshield washer system, including the jets, checked during routine maintenance
to verify everything is working properly. How often should windshield washer jets be adjusted?
There is no set number of years or miles that windshield washer jets are supposed to work, so just keep an eye out for any strange spray patterns, if the jets are missing your windshield, or if they stop working altogether.
Can I adjust my windshield washer jets myself?
It’s possible to adjust windshield washer jets at home—but if you aren’t confident in your DIY skills, you should definitely take your vehicle to the professionals to make sure the job is done right.
