How to Determine When to Replace Windshield Wipers
2 Answers
Signs indicating the need to replace windshield wipers include: 1. Aging or cracking of the wiper rubber due to prolonged use; 2. Squeaking noises during operation; 3. Streaks or marks left on the windshield; 4. Wipers skipping or chattering during use. Windshield wipers, also known as wiper blades or windscreen wipers, are blade structures installed in front of the windshield. The components of windshield wipers include: motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade. Their functions are: 1. To remove raindrops and dust adhering to the vehicle's windshield; 2. To improve the driver's visibility and enhance driving safety.
Having driven for over 20 years, I've summarized a method to determine whether wiper blades need replacement, focusing on practical performance and safety. On rainy days, activate the wipers—if they leave streaks, smudges, or blurred vision after wiping the windshield, the rubber has aged. At this point, pinch the wiper blade; if it feels stiff or shows cracks, it’s time to replace it. Otherwise, driving in the rain poses significant risks, as poor visibility could lead to accidents. I recommend checking every six months, especially before seasonal changes, as summer heat and winter cold accelerate aging. If the wipers make noise or skip while driving, don’t ignore these small signals—addressing them promptly avoids bigger issues. Remember, replacement is simple and inexpensive—don’t gamble with safety.
