How Often Should You Replace Windshield Wipers?
It's always best to replace wiper blades as soon as they show any signs of wear or lack of performance. All wiper blades will eventually wear out with use and over time. The wiper assembly consists of the rubber wiper blade insert and bracket which is connected to the wiper arm. The wiper arms are powered by the windshield wiper motor, which is controlled by the wiper switch, wiper relay, and one or more fuses. This means it's possible to have an electrical component failure in the wiper system as well, which is usually indicated by the wipers not activating or failing to operate at the selected speed.
It’s a good idea to regularly inspect your wiper blades, especially before spring and winter, and replace them when needed to ensure optimal visibility and safety while driving. It's also recommended that you replace wiper blades in pairs, as they experience the same conditions and usage and are likely to fail around the same time.

What Causes Wiper Blades to Fail?
When wiper blades fail prematurely, one of the most common reasons is harsh environmental factors, such as prolonged exposure to heat or cold, which can weaken the rubber blade and lead to a cracked or partially-detached blade insert. Once the rubber is weakened, the blade becomes more susceptible to damage. Overuse or contact with ice or debris may cause the rubber to split and begin to peel away from the wiper bracket. Early signs of wiper failure usually include noticeable wear along the wiper blades' rubber edge, creating a streaking effect or squealing noise caused by the rubber no longer maintaining proper elasticity for consistent windshield contact. In this case, you can either replace the pair of wiper blades, or if necessary for your specific vehicle or wiper blade design, install wiper refills.
If your wipers are slower than normal, only operate at certain settings, or will not activate at all, then there is likely an issue with your wiper’s electrical system components. Replacing your wiper blades will not fix a malfunctioning wiper system, and a new windshield wiper switch, windshield wiper relay, or windshield wiper motor might be required for a complete repair. Always inspect the fuse, wiper relay, and wiper switch before replacing a wiper motor, since those smaller components can exhibit the same signs of failure.
