What Causes Insufficient Windshield Washer Spray Height?
2 Answers
Low pressure in the windshield washer spray may be caused by clogged nozzles or blocked washer fluid hoses, resulting in reduced pressure and insufficient spray height. Adjusting the spray height: The windshield washer spray height can be adjusted using a large needle. Be careful not to apply too much force during adjustment to avoid damage. The washer nozzles have a flat opening, so a flat-head screwdriver can also be used. Solutions for weak or no spray: 1. Check if the washer fluid (windshield cleaner) is depleted, preventing the pump from drawing it. Simply refill the washer fluid. 2. Determine if the washer pump is working by listening for its sound when activating the spray switch. If there's no sound, the pump may be burned out. 3. If washer fluid is present and the pump is working, open the engine hood to inspect the washer fluid supply hose for leaks.
I just dealt with the issue of weak windshield washer spray last month. At first, I noticed the washer fluid reservoir was nearly empty, but after refilling it with washer fluid, the problem persisted. Upon closer inspection, I found the spray nozzles were completely clogged with tree sap. It took me quite a while to clear them out using a needle. Additionally, I noticed the spray angle was off, shooting up into the sky. I spent half an hour adjusting it by inserting a paperclip into the nozzle and bending it left and right. This job requires patience; haphazard poking can easily damage the nozzles. If you can't manage it yourself, it's better to take it to a repair shop—they can clean it out quickly with an air gun. By the way, when using concentrated washer fluid recently, it's important to dilute it properly; adding too much can also clog the nozzles.
