How often should the wipers of a new car be replaced?

[VivienneLee]

The wipers of a new car generally need to be replaced every 1 to 2 years. The replacement time varies depending on the quality of the wipers, usage environment, and maintenance level. The standard for replacing wipers is: when the wiper blades leave water streaks, scratches, or make unusual noises after wiping, and fail to achieve a clean and streak-free effect on the windshield, it's time to replace them. Wipers, also known as windshield wipers, are devices used to remove rain and dust from the vehicle's windshield. The power source of the wipers comes from an electric motor, which is the core of the entire wiper system. It typically uses a DC permanent magnet motor, often integrated with a worm gear mechanism. The worm gear mechanism serves to reduce speed and increase torque, with its output shaft driving a four-bar linkage mechanism that converts continuous rotational motion into a left-right oscillating motion.
