What are the reasons for the Touareg wiper not spraying water?

The reasons for the Touareg wiper not spraying water are: 1. Clogged spray nozzle; 2. Low windshield washer fluid level; 3. Damaged hose or loose connection; 4. Faulty spray motor. Taking the 2017 Touareg as an example, it is a compact SUV with body dimensions of length 4506mm, width 1809mm, height 1685mm, a wheelbase of 2684mm, and a body weight of 1600kg. The 2017 Touareg is equipped with a 1.8T turbocharged engine, delivering a maximum horsepower of 160PS, maximum torque of 250Nm, and maximum power of 118kW, paired with a 6-speed automatic transmission.
A few days ago while driving, I noticed my Tiguan's windshield wipers suddenly stopped spraying water, making the driving visibility blurry and quite dangerous. Thinking carefully, there could be several reasons for this. The most common one is the washer fluid reservoir being empty—meaning the windshield washer fluid has run out—since the car often drives on dusty roads, using up the fluid quickly. Secondly, clogged spray nozzles are also common; for example, sometimes I forget to clean the nozzles during car washes, and dirt gets stuck inside. A broken water pump is also troublesome—this part is responsible for pumping the fluid, and if it's worn out or has an electrical fault, the entire system fails. Leaks in the hoses or connections can also prevent the fluid from reaching its destination, especially in winter when the pipes age. Electrical issues shouldn't be ignored either, such as a blown fuse protecting other components under extreme current. Another major factor is the fluid freezing in cold weather—I learned this the hard way when I didn't add antifreeze while using the car. Suggested inspection sequence: first, open the reservoir cap to check the fluid level, then clean the nozzles, and finally inspect the fuse box—if you're a beginner, it's easier to visit an auto repair shop. Preventive measures like regularly adding proper windshield washer fluid and checking the nozzles can avoid similar issues.
Speaking of the issue with the Tiguan's windshield wipers not spraying water, I've tinkered with it a few times myself, mostly due to daily neglect. The washer fluid reservoir might be empty—forgetting to refill or it leaking out can cause this. Nozzle clogs are common; dust can block the tiny holes on highways, preventing water flow. A worn-out or damaged water pump isn’t unusual either, especially as vehicle parts fatigue over time. Leaky hose connections are another culprit, where loose or cracked fittings lead to fluid loss. Fuse blowouts often happen during electrical shorts, like when modules fry after getting soaked in rain. Winter freezing is even more annoying—water freezes without antifreeze. Troubleshooting isn’t complex: first, try adding water to see if it sprays; if not, use a needle to unclog the nozzle. For DIY fixes, check the wiper-related fuse in the fuse box and replace it with a spare. Remember to use quality washer fluid to prevent clogs and freezing. If that still doesn’t work, it might be a deeper electrical issue—best handled by a pro shop for a small cost. Always keep tools handy in the car for quick fixes without delays.
