Wiper Blades: what it does & when to replace it
Wiper blades clear rain, snow, and debris from the windshield for visibility. The rubber edge degrades from sun and use; most blades need replacing every 6–12 months. Replacement signs include streaking, skipping, chattering, or squeaking across the glass. Blade length is specific per vehicle and the driver and passenger sides are often different lengths. This is the single easiest car-maintenance task — most blades clip on in under a minute with no tools — and a clear safety upgrade that is frequently neglected.
DIY difficulty: Very easy DIY (under a minute, no tools). Always confirm the correct part for your exact build by VIN before buying.
