What Are the Reasons for Weak Windshield Washer Spray Pressure?

Possible causes include low washer fluid level or clogged spray nozzles. Below is relevant information about windshield wipers: 1. Introduction: Wipers, also known as windshield wipers, water wipers, or rain wipers, are devices used to wipe away raindrops and dust attached to the vehicle's windshield, improving driver visibility and enhancing driving safety. Due to legal requirements, almost all vehicles worldwide are equipped with wipers. Rear windows of vehicles such as hatchbacks and SUVs also have wipers. Besides automobiles, other transportation vehicles like trains and trams are equipped with wipers. Some engineering machinery, such as cranes, also have wipers installed. 2. Structure: Composed of an electric motor, reducer, four-bar linkage mechanism, wiper arm spindle, and wiper blade assembly, its main function is to remove rain, snow, and dust that obstruct the view on the windshield.

The windshield washer spray pressure is low. I've encountered this several times. It's usually because the washer fluid reservoir level is too low, so you need to top up the windshield washer fluid promptly. Alternatively, the nozzle might be clogged with dust or small stones, affecting the water spray. You can gently clean it with a pin. Another possibility is a leak or aging/cracking in the hose, causing pressure loss. Sometimes, the water pump malfunctions, and its operating sound becomes weaker, requiring replacement. Also, a dirty filter needs cleaning. Remember to regularly check these areas to prevent sudden issues, avoiding situations where you can't see the road clearly during rain.

I always forget to add windshield washer fluid when washing my car, and I noticed the water spray pressure has decreased. The possible reasons could be an empty reservoir or clogged nozzles; air leaks in the hose or water pump failure might also be related. I once accidentally used tap water, which caused scale buildup inside. It's recommended to regularly use dedicated wiper fluid for antifreeze and anti-contamination purposes. Check if the hose connection points are loose. Replacing a new spray nozzle only costs a few dozen yuan. Addressing these issues promptly can prevent poor visibility of vehicles ahead during heavy rain, which is quite important.

Having driven for decades, insufficient washer fluid pressure is often due to clogged nozzles or low fluid reservoir levels; cracked hoses or aging pumps are also common causes. In my younger days of frequent car repairs, I'd recommend removing nozzles for warm water flushing; always use proper washer fluid instead of plain water, and remember winter antifreeze measures to prevent ice blockages. Maintaining system cleanliness is crucial.
