What is the reason why the wiper cannot move?

[MargaretDella]

The reason why the wiper cannot move is that the motor is damaged, and replacing it with a new motor will solve the problem. The wiper is a blade structure installed in front of the windshield, consisting of a motor, reducer, four-bar linkage, wiper arm spindle, wiper blade assembly, etc. Its main function is to remove rain, snow, and dust on the windshield that obstruct the view. 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 relatively high. It uses a DC permanent magnet motor, and the wiper motor installed on the front windshield is generally integrated with the worm gear mechanical part.

There are many reasons why wipers may stop moving. The most common issue is a malfunctioning wiper motor, such as burning out or failing to turn, often caused by prolonged use or unstable voltage. Secondly, the wiper linkage mechanism may rust or get stuck, especially in rainy or humid winter conditions. Additionally, a blown fuse can cut off power to the entire circuit, so you need to locate and check the corresponding fuse in the fuse box. Wiper blades freezing or being obstructed by debris can also prevent movement—clearing snow, ice, or leaves promptly can resolve this. Regular maintenance, such as lubricating the linkage and checking the motor's condition, can prevent unexpected failures. This problem is particularly dangerous when driving in the rain, so it's crucial to address it promptly to avoid risks.

It's really frustrating when the windshield wipers suddenly stop working while driving. I've encountered this issue several times, mostly due to the wiper arm being jammed by small branches or ice—simply disassembling and cleaning it usually solves the problem. If the wiper motor is aging, it's prone to burnout, especially with frequent use. Fuse issues are also common, and a quick replacement with a new fuse can help diagnose the problem. Additionally, malfunctioning wiper switches or poor wiring connections can interrupt operation. Regular maintenance is crucial—avoid dry wiping the windshield or using the wipers unnecessarily in rainy conditions. DIY repairs aren't complicated, but if you're unsure, it's best to visit a professional shop. Safety comes first to prevent accidents on the road—clear visibility ensures peace of mind while driving.

The reasons for wiper failure can be divided into electrical and mechanical aspects. Electrical issues include blown fuses, motor failure, or switch damage; these can be detected using a multimeter to measure voltage. Mechanical problems involve rusted or deformed linkage arms causing jamming – try disassembling and lubricating them. When wiper blades are frozen or blocked by leaves, simple cleaning may suffice. Follow this troubleshooting sequence from easy to difficult: first check fuses, then inspect switches and wiring connections, and finally evaluate the motor. Regular maintenance can prevent issues and keep the wiper system operating smoothly.

When windshield wipers fail to move during rainy weather, it poses a significant danger and can compromise driving safety. Potential root causes include a burnt-out wiper motor, a stuck linkage, or a blown fuse. If the wiper blades are frozen to the glass, forcing them to move can easily damage the mechanism. It's crucial to test the wiper function before driving in the rain, and if any issues are detected, stop immediately to repair or seek assistance. Regularly inspect the wiper system's condition to prevent rust or aging problems. Ensuring clear visibility helps reduce the risk of accidents.

To prevent the wipers from getting stuck, daily maintenance is key. Regularly clean the wiper arms and glass grooves to avoid debris jamming or rust. Before winter, check if the wiper blades are frozen stiff and replace them with anti-freeze types if necessary. The wiper motor has a limited lifespan, so avoid continuous dry wiping to protect it. Fuses can easily blow, so replace them with spares promptly. If the wipers get stuck, turn off the switch and try manually shaking them. Maintaining the wipers in good condition year-round can save you from unexpected troubles on the road.
