What are the reasons for windshield wipers not spraying water?

The reasons for windshield wipers not spraying water are: 1. The wiper nozzle is clogged or the pipeline is detached. It is recommended to check the spray nozzle; 2. The fuse is blown and needs to be replaced. The power source of the wiper comes from the motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high, using a DC permanent magnet motor. The wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part. The function of the worm gear mechanism is to reduce speed and increase torque. Its output shaft drives the four-bar linkage, which converts continuous rotational motion into left-right oscillating motion.
I've been driving for decades and have encountered the issue of windshield wipers not spraying water several times. The most common reason is simply that the washer fluid reservoir is empty. Quickly refilling it can often solve the problem. Nozzle clogging is also a frequent occurrence, where dust or mud blocks the holes. Gently cleaning them with a fine needle usually does the trick. When the washer pump fails or makes no sound, it might be due to a blown fuse or loose wiring connections. In winter, frozen washer fluid can be more troublesome—switch to antifreeze instead of pouring hot water. Aging and cracked hoses are also common, so it's important to check for leaks in the piping. Regularly inspecting the fluid levels and pipes helps prevent small issues from becoming big ones. Driving with poor visibility in the rain is too dangerous, so get it fixed as soon as possible to ensure safety.
Last time my new car's windshield wipers wouldn't spray water, which really worried me. I thought it was just out of fluid, but refilling didn't help. Upon closer inspection, I found the nozzles were clogged with insect remains - they worked immediately after cleaning. Cracked or detached hoses can also cause leaks, while another common reason is a blown fuse or motor failure in the washer pump. Last winter I forgot to use antifreeze and the tubes froze, preventing water spray - I almost damaged things trying to fix it myself. Now I've learned basic maintenance: regularly checking fluid levels and hoses. When wiper spray fails while driving, dirty windshields reduce visibility and increase accident risks, so it's crucial to address the issue promptly.
When using the car daily, if the windshield wipers aren't spraying water, first check if the washer fluid tank is empty. Refilling the windshield washer fluid usually solves the problem. The nozzles are prone to dust accumulation and clogging, so use a cotton swab or soft needle to carefully clean the holes, being gentle to avoid damage. Loose tubing or a faulty pump could also be the cause—if there's no sound when spraying, it might indicate a serious issue. When the weather turns cold, switch to antifreeze windshield washer fluid in advance to prevent the hoses from freezing. Ignoring these issues can lead to impaired visibility while driving, which is very dangerous. Handle simple faults yourself, but leave more complex problems to a mechanic for quicker resolution.
