How to fix windscreen wiper?

To repair a car's windshield wipers, targeted measures should be taken based on specific issues. If the wipers do not clean the windshield properly, first use a damp cloth to remove dust or gravel from the rubber blade surface. For minor wear on the rubber blade, use 1000-grit sandpaper dipped in water to gently sand both sides and the edge for about 5 minutes to restore wiping performance; if severely worn, replace the wiper blade (starting from approximately 79 Malaysian Ringgit). When wipers fail to move, first check for blown fuses, then inspect motor plug voltage or potential disconnection in the linkage mechanism. Always disconnect power and place a protective towel to prevent glass damage from wiper arm recoil during service. Select vehicle-specific attachment types (e.g., UNI-V's dedicated clip design) when replacing, and verify wiping performance and noise levels post-installation. Conduct bi-annual rubber blade inspections and perform pre-rainy season maintenance to ensure optimal visibility.
