How to Check Your Car's Wiper Blades and When to Replace Them
Learn how to inspect wiper blades and recognise when replacement is needed for safe visibility.
Understand common causes of blade wear and how climate affects wiper performance.
Quick Answer
Wiper blades play an important role in visibility and driving safety, particularly during heavy rain. Exposure to sunlight, heat, dirt, and environmental contaminants gradually hardens and damages the rubber wiping edge. Because Malaysia experiences frequent rainfall and high temperatures, regular inspection is especially important. Drivers should not rely solely on age or mileage; blade condition and wiping performance provide better indicators of when replacement is needed.
When to Check or Replace
- Inspect blades every few months.
- Check before monsoon season or long-distance trips.
- Replace when wiping performance deteriorates.
- Replace damaged or hardened blades promptly.
Signs of Wear
- Streaking across the windscreen.
- Skipping or chattering during operation.
- Cracked or split rubber.
- Areas of glass left uncleared.
What Affects Service Life
- UV exposure.
- Heat and humidity.
- Frequency of use.
- Windshield cleanliness.
What to Do
- Clean the windscreen regularly.
- Wipe dirt from blade edges periodically.
- Replace worn blades before visibility becomes compromised.
