Why Doesn't the Windshield Washer Fluid Spray in Winter?
2 Answers
Here are the reasons why the windshield washer fluid doesn't spray in winter: 1. Clogged spray nozzle: For example, waxing or washing the car may block the spray nozzle, or frequently using inferior windshield washer fluid or directly using tap water. 2. Damaged washer pump or circuit failure. 3. Clogged filter screen, etc. Additional Information: When purchasing windshield washer fluid, pay attention to choosing products with clear production dates, neat packaging, and no strange odors. Ensure there are no sediments in the product. Otherwise, injecting unqualified windshield washer fluid may cause your car to freeze. Especially note that the product should have a labeled freezing point. Depending on your needs, you can choose windshield washer fluid labeled for -20 degrees, -25 degrees, or even -40 degrees to ensure it doesn't freeze under corresponding extreme cold conditions.
The most common reason for windshield washer fluid not spraying in winter is that the water is frozen. After all, when the weather is extremely cold, water can freeze directly and block the nozzles. I've encountered this issue several times, especially in northern regions where temperatures drop below zero in the morning. Pressing the button yields no spray, leaving the entire windshield blurry and making driving particularly hazardous. Actually, aside from freezing, the nozzles might be clogged by dirt or residual fluid, or the washer pump motor could be stuck—it simply won't operate when it's too cold. It's advisable to use winter-specific antifreeze washer fluid and not skimp on the small cost, as regular water will definitely freeze below zero. If it's already frozen, avoid forcing the spray. Instead, you can drive the car into a warm garage to let it thaw or pour warm water over the nozzle area to melt the ice—but avoid using boiling water to prevent damaging the components. During regular maintenance, have a technician inspect the system to prevent minor issues from escalating.
