Your car's windshield washer is one of those things that you don't realise how often you use until you're without it. Not being able to use your windshield washer is a real inconvenience, but it's also dangerous to drive without a clear field of vision. If you find that your windshield washer isn't spraying cleaning fluid onto your windshield, it may be that one or both of the nozzles are clogged. Not to worry, it is fairly easy to unclog them yourself.
Check your washer fluid reservoir to make sure that it is not empty. If it is empty, refill it and try operating your windshield sprayers. It may simply be that your car is out of wiper fluid.
Stick a straight pin or a toothpick into the nozzle to dislodge any foreign objects that may be clogging it.
Open the bonnet of your car and locate the nozzle hose. Disconnect the hose from the nozzle and blow compressed air through it to remove any debris that may be in the hose and not actually in the nozzle. You may also try flushing it with water from a garden hose. Check to make sure the windshield washer hoses are not kinked, twisted, loose or cracked.
Open the washer fluid reservoir and check it for debris. If there is debris in the reservoir, flush it out with water so the debris will not be pumped into the hoses or the nozzles.
Inspect your car's nozzles for ice in winter months. Windshield washer fluid typically contains antifreeze to keep the fluid from freezing. However, snow or ice may accumulate on the bonnet of your car and get into your windshield washer nozzles, clogging them. Remove frozen clogs with deicer, a hairdryer or by simply letting your car engine heat the nozzles.
