What Causes Weak Wiper Performance?

[DeJuliana]

Weak wiper performance is typically caused by excessive friction between the wiper blade and the windshield. It could also result from a malfunctioning wiper motor or increased resistance due to insufficient lubrication in the linkage mechanism. The wiper system is an essential device for every driver during rainy conditions, ensuring the front windshield remains clear of water to maintain visibility while driving in wet weather. The power source of the wiper comes from an electric motor, which serves as the core of the entire wiper system. The quality requirements for wiper motors are exceptionally high, as they utilize DC permanent magnet motors. The wiper motor installed on the front windshield is generally integrated with a worm gear mechanism, which functions to reduce speed and increase torque. The output shaft drives a four-bar linkage mechanism, converting continuous rotational motion into a side-to-side oscillating movement.
