How often should wiper blades be replaced on a new car?
2 Answers
Wiper blades on a new car should generally be replaced every two years. Wiper blades are devices used to sweep away raindrops and dust attached to the vehicle's windshield, improving the driver's visibility and enhancing driving safety. Wiper blades are blade-like structures installed in front of the windshield, consisting of components such as an electric motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. Their primary function is to clear rain, snow, and dust that obstruct the view on the windshield. The power source for the wiper blades comes from an electric motor, which is the core of the entire wiper system. The quality requirements for the wiper motor are quite high, typically using a DC permanent magnet motor. The wiper motor installed on the front windshield is usually integrated with the worm gear mechanical components.
I've been driving for years, and there's no fixed rule for how often to replace wiper blades on a new car. When I drive a new car, I usually check them every six to twelve months. The wear rate depends on your driving habits and weather conditions: if the car is often parked under direct sunlight or you experience frequent rainy seasons, the wiping performance deteriorates faster. Listen for sounds—if the wipers squeak or leave streaks and blurred vision, replace them immediately. Don’t skimp on this; poor visibility while driving is dangerous. Before replacing, try cleaning the wiper blades with glass cleaner—sometimes dirt buildup can temporarily improve performance, but it’s not a permanent fix. Always check before the rainy season—safety first. Remember, wiper lifespan also varies by quality; buying higher-end blades can last longer. Parking in a garage to minimize rain exposure can help extend their life.
