Six easy steps to replace your windscreen wipers

To change your car's window wiper blades, you can fit new wiper blades, or replace the whole wiper blade assembly, depending on whether the wear or damage is only to the rubber blade or to the wiper assembly. They’re both readily available from spare parts stores like Repco where NRMA Members save on select products. 

1. Find the right size wiper blade. You can check the application guide at the spare parts store, or measure the blade claw width yourself. The choice between universal or specific fit, plastic or metal backed, single and multiple edge, or rubber or silicone blades is yours.
   
   If you're not sure what to choose, you can call our Motoring advice team on 13 11 22 or ask a retail assistant who'll be able to guide you.
2. Lift the wipers from glass. The windscreen wiper claws are spring loaded against the glass. Lift them fully from the windscreen before removing the blades. Be careful not to let the wiper arms spring back or they could damage the glass.
3. Remove the old wiper blades. Remove each of the old wiper blades by squeezing the clip on the end and sliding the blade from the wiper assembly – you might need a pair of long-nose pliers to help you release the clip.
4. Slide on the new blades. Slide the new wiper blade through the claws on the wiper assembly until the clip clicks in at the end – universal wiper blades have two sets of grooves, the upper to suit 6.5mm wiper arms and the lower to suit 8.5mm. Make sure the claws are in the right groove – and that you haven’t missed any claws – to ensure the blades can’t come loose and cause damage to your windscreen.
5. Trim the new blades if necessary. If you’re using universal blades or blades that aren’t exactly the right length, cut off the end of the blade opposite the clip using cutters or scissors, leaving about 3cm sticking out from the claw on the end.
6. Check that the new wiper blades work well. Carefully lower the wiper assembly back onto the windscreen. Check that your windscreen washer bottle is full of water and add some wash additive if you wish. Now, check that the wipers work correctly using the car’s windscreen washer function.
   
   Important: Do not dry test the wipers as they may scratch the glass.
