How to Determine When to Replace Windshield Wipers
2 Answers
If the windshield wipers show signs of cracking, aging, rusting, deformation, contamination, or discoloration, they should be replaced promptly. Here is some information about windshield wipers: 1. Function of Windshield Wipers: Windshield wipers are important accessories installed on the windshield, designed to clear rain, snow, and dust that obstruct the driver's view. Therefore, they play a crucial role in driving safety. 2. Types of Windshield Wipers: Windshield wipers generally include vacuum wipers, electric wipers, and wipers with electronic control units. The drawback of vacuum wipers is the unstable speed of the wiper blade, which can stop when the engine's vacuum pressure decreases (e.g., when the car is climbing a hill), leading to obscured vision for the driver. Vacuum wipers were phased out in 1972 and replaced by electric wipers.
As someone who drives long distances year-round, I know well that wiper quality is crucial for driving safety. Here's how to tell when replacement is needed: Focus on three main indicators. Poor wiping performance is key - if you notice streaks, water beads, or blurred areas after wiping during rain that obstruct visibility; listen for unusual sounds like chattering or squeaking caused by increased friction from aged rubber; inspect the blade itself for cracks, hardened spots, or deformed edges indicating wear. Seasonal factors matter too - winter and spring rains often expose problems. I make it a habit to test wipers quarterly by activating them with washer fluid. Replace immediately if any issues appear - don't hesitate. Clear visibility prevents accidents, while delayed replacement increases risks. Choose quality brands - DIY replacement is simple, and never compromise safety to save small money.
