windshield wipers are used to remove water, snow, dirt, and other debris from the front window to enable the driver to see the road. Also, referred to as a wiper blade or windscreen wiper. They must be fitted for all motor vehicles, including cars, buses, trucks, train locomotives, and even aircrafts. Windshield wipers are mandatory and a legal requirement for all vehicles.
Most windshield wipers come with a windshield washer as well. This is a pump that dispenses water along with some detergent from a tank in the hood to the windshield. The fluid is sent through small nozzles attached to the hood. Typically, conventional nozzles are used, but recent advancements have led to a fluidic oscillator that disperses the fluid more effectively onto the windscreen.
Wiper blades are extremely important for the overall safety of the vehicle and the people inside them. It is important to check the wiper blades periodically to ensure they are functioning properly in removing water and debris from the windscreen. If your wiper has stopped working or is not wiping well, it is time to get them replaced.
Learning how to replace wiper blades is simple and easy, you can remove and replace the wiper blades without using any tools!
Deciding which part of the blades to change
Before you rush in to buy new wiper blades, check which part of the blade you want to replace.
The wiper assembly contains two parts: the arm attached to the hood and, the wiper blade that is attached to the arm. Check both parts for any defects.
You must also note, that the rubber insert resting against the windshield glass is not sold separately. In this case, you will have to replace the entire blade.
Buying new wiper blades
Firstly, it is important to identify the correct wiper blade according to the year, make, and model of your vehicle. Some vehicles use wiper blades of different lengths on the driver's side and the passenger's side. If your vehicle has a rear wiper, you should consider changing this blade at the same time as our front windshield wipers. After Identifying the problem with your wiper blades, you can now work on removing your current wiper blades.
Removing the old wiper blades
Before removing the old wiper blades, ensure that the engine of your vehicle is turned off. Now, pull the entire wiper assembly arm from the windshield, into a standing position. Repeat this with the other wiper arm as well. Pull the wipers only as much as they come away from the windshield. Do not try to force the wipers to a standing position if they don’t come forward.
Releasing the wiper blades
Once you position the wipers, lookout for a small tab on the underside of the blade. This is normally near where the rubber insert and the metal arm meet. Then, push or pull, as the case may be, to release the blades. Pull the blade down to slide it off the metal arm’s hook.
Sometimes accumulated dirt or debris around the blade can make it difficult to remove the blade. Just tap on the blade to remove the debris and pull up the blade.
You can also try pushing the wiper up into the holder and then pressing the tab to make it easier to remove the blade.
At this stage, the bare metal arm is exposed. This could be risky if left as is and can snap back and damage the windshield. To be safe, hold the metal arm gently and place it back against the windshield. You can also keep a cloth below the metal arm to prevent scratches or damage to the windshield.
Taking out the new wipers
Remove the new wipers from the packaging. If you have purchased two wipers for the front windshield, it could be that the left and right wipers are of different sizes. Check the wipers and match each to the correct side.
Installing the new wipers
Installing your new wiper blades:
- Push the movable hinge on the new blade to make it perpendicular to the rest of the blade.
- Position the new blade up with the metal arm so that the metal hook goes into the hole in the blade. Then, push the metal hook through the hole in the blade.
- Pull up on the blade until you feel and hear it click into place.
- Finally, push the blade back down gently to its resting position against the windshield.
Repeat the above steps with the other wiper blade.
Checking the wiper arm angle
Once you have installed the new blade, check the wiper arm angle. An off-angle can cause clattering. To prevent this, ensure that the blade is at an angle of 90 degrees to the glass mid-swipe. This is because the angle from the top of the windshield to the bottom of the windshield will change due to the curvature of the glass.
Trying out the new wipers
Check if you have installed each blade on the correct side. Also, confirm that the wiper is properly oriented. If you find a problem, reach out to a local professional for assistance.
