Which switch is for spraying windshield washer fluid?
2 Answers
The windshield washer fluid switch button is usually located on the outermost part of the left/right control lever on the steering wheel. Pressing it down will spray the washer fluid, and the wipers will also operate simultaneously. Some car models do not have a physical button and require the lever to be pulled toward the driver and held for a while to activate. Below are the functions of windshield washer fluid: 1. Cleaning performance: Windshield washer fluid is formulated with various surfactants and additives. Surfactants typically have functions such as wetting, penetrating, and solubilizing, thereby removing dirt. 2. Anti-freeze performance: The presence of alcohol and ethylene glycol in the washer fluid significantly lowers the freezing point of the liquid, preventing freezing and quickly dissolving frost. 3. Anti-fog performance: The washer fluid forms a single-molecule protective layer on the glass surface, preventing the formation of fog droplets and ensuring clear visibility. 4. Anti-static performance: After cleaning with washer fluid, substances adsorbed on the glass surface can eliminate static charges, providing anti-static properties. 5. Lubrication performance: The ethylene glycol in the washer fluid has high viscosity, providing lubrication to reduce friction between the wipers and glass, preventing scratches. 6. Anti-corrosion performance: The washer fluid contains various corrosion inhibitors, making it completely safe for all metals, car paint, and rubber without any corrosive effects.
After driving for so many years, the switch for spraying windshield washer fluid is usually the end button or small lever head on the left-side wiper control stalk. When operating, you gently push forward or press it, and the fluid sprays directly onto the windshield to clean stains. Remember not to spray when the reservoir is empty to prevent burning out the washer motor. I check the washer fluid level every month, especially during the rainy season, and top it up with antifreeze type for added safety. Some car models have slightly different button placements, but it's always linked to the wipers—press it, and water sprays out, ensuring clear visibility for safer driving. Developing this habit also saves money on repairs, and it's super practical for clearing dust and bugs.
