What are the consequences of not adding windshield washer fluid for a long time?

Not adding it doesn't have much impact, but when the windshield gets dirty, you can't turn on the washer switch. Using the washer function for a long time without washer fluid can burn out the washer pump motor, as the fluid itself provides lubrication and cooling for the pump motor. Secondly, not having washer fluid poses a significant safety hazard while driving. Without washer fluid, you can't clean the windshield promptly, which can affect visibility. Below are the functions of windshield washer fluid: Anti-freeze performance: Windshield washer fluid should have certain anti-freeze capabilities. Most commercially available fluids can withstand temperatures down to -20°C, with the lowest anti-freeze temperature reaching -115°C. Anti-corrosion performance: The fluid contains various corrosion inhibitors that protect metal components, car paint, and rubber from corrosion, thus safeguarding the paint and pipelines.
