What is the reason why the wiper cannot move?
2 Answers
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.
