How to inspect and replace wiper blades

30th November 2020

Inspect your wiper blades about every six months. Even if you don't use them very often, the rubber can deteriorate with time. If your wiper blades are faulty or worn, it's likely they won't be able to grip your windscreen properly. This means they won't be able to remove things like mud, rain or snow effectively.

Check your vehicle owner's manual or the packaging included with your wiper blades for the best info and, if in doubt, chat with your mechanic.

Change your wiper blades as soon as you notice they're not making contact with your car's windshield. This may happen every 6-12 months or so. If you're not sure, ask a professional.

If you're game enough to replace your own wiper blades, you'll need:

• your new wiper blades
• scissors or a craft knife, and
• pliers.

If you're unsure about the process, leave the job for your mechanic.

Once you're ready to go, follow these steps to replace your wiper blades:

• Remove your old wiper blades. After lifting the wiper blade away from your car's windshield, press the small clip beneath the rubber wiper where it connects to the wiper assembly. You should be able to slide the wiper blade off by pulling on it gently. If you're having trouble, try using your pliers to depress the clip.
• Install the new wiper blades. Attach the wiper blade to the wiper assembly. You should hear a clicking sound as it clips into place. The wiper assembly is spring loaded, so carefully lower it back onto the windshield to avoid cracking the glass. Repeat this step with the other wiper blade. If you find that the blades are too long, snip the ends off with your scissors or craft knife leaving approximately 3cm sticking out from the claw at the end of it.
• Make sure they work. Test your new wiper blades so you know they're installed correctly. You can do this using your car's windscreen washer function. Before you do, check the windscreen washer bottle is full. Top it up with water and washer additive. If you don't, and the wiper blades are used, you risk scratching your windscreen.

If you're unsure about the process, leave the job for your mechanic.
