A windscreen wiper is a device used to remove rain, snow, ice and debris from a vehicle’s front window. It is a legal requirement for almost all motorised vehicles to be equipped with wiper blades.
This is a job the mechanics will normally try and upsell you on when you service your car, but don't fall for it! Replace them on your own at minimal expense to your bank account.
A wiper generally consists of a metal arm; one end pivots, the other end has a long rubber blade attached to it. The arm is powered by an electric motor. The blade is swung back and forth over the glass windscreen, pushing water, or other impediments to visibility, from its surface.
Your wiper blades are going to perish over time, so it’s recommended you change them every six months. If you don’t, you will suffer visibility issues and possible even see scratches appear on your windshield. Replacing windscreen wiper blades is as easy as:
- Measuring you wiper blades
- Removing the old wiper blades
- Attaching the new wiper blades
- Testing them out
How to remove windscreen wiper blades
- Measure your wipers: Windshield wipers come in several sizes, and if you use the wrong ones, they either won’t fit or won’t work correctly. If in doubt about the correct size, simply look in your owner’s manual.
- Remove the old wipers: Gently lift the arm away from the windscreen, then press the small tab under the wiper where it meets the arm. The wiper blade should then slide right off the arm when you pull downward.
How to install windscreen wiper blades 1. Attach the new blade: First confirm that the new blade uses the same hooks as the old, then attach to the arm. You should hear a clicking sound as the new blade locks in place. Gently lower the arm back to the windscreen before repeating the process of the other one.
Test them out
Don’t wait until a downpour to see if you did the job correctly. Turn the wipers on and off the make sure they work effectively and don’t come loose.
Some vehicles are fitted with wipers (with or without washers) on the back window as well. Rear-window wipers are typically found on hatchbacks, station wagons / estates, sport utility vehicles, minivans, and other vehicles with more vertically-oriented rear windows that tend to accumulate dust.
In the 1960s, as interest in auto safety grew, engineers began researching various headlamp cleaning systems. Headlight wipers have all but disappeared today. If your vehicle is fitted with Rear Wipers, or the now almost non-existent Headlight Wipers, the above procedures can be followed for wiper replacement also.
