What Causes Windshield Washer Fluid Not to Spray in Winter?

[JuniperAnn]

In winter, the most common reason for windshield washer fluid not spraying is that the added fluid lacks sufficient antifreeze capability and freezes. For example, in winter temperatures around -10°C, a washer fluid with a freeze resistance of 0°C is typically used. Other causes include clogged windshield nozzles, damaged washer pump or electrical faults, leaks in the washer fluid lines, or insufficient washer fluid levels. It is recommended to choose a washer fluid with antifreeze capability of at least -25°C or -40°C based on the winter driving environment. Here are the correct ways to use windshield washer fluid: 1. Spray it on the area to be cleaned, let it soak for 2-3 minutes, then wipe with a soft cloth or directly apply the cleaning solution with a soft cloth until the area is clear. 2. For heavily soiled areas, repeat the cleaning process and rinse with clean water, then dry thoroughly. 3. After dilution, it can be directly poured into the vehicle's windshield washer reservoir for use while driving.
