How to Replace Old Windshield Wipers?

Are your windshield wipers not performing as well as they used to? It might be time to replace them. In this guide, we’ll show you how to replace your old windshield wipers with ease. By following these simple steps, you can ensure clear visibility and a safer driving experience. Let’s get started!

How to Remove the Old Windshield Wiper

When it’s time to replace your old windshield wipers, the first step is to remove the old blades. 

Before you start, ensure that your car is turned off, in park, and that the emergency brake is engaged for safety.

To remove the old wiper blade, lift the wiper arm away from the windshield. Locate the tab or buttons on the bottom of the wiper blade where they connect to the arm. 

Depress the tab and pull the center of the blade towards the bottom of the arm to slide the blade off the arm. 

It’s recommended to remove and replace one blade at a time.

How to Install the New Wiper Blade

Now that you have successfully removed the old windshield wiper, it’s time to install the new one. Follow these simple steps to ensure a proper installation:

  1. Gather your new wiper blade: Start by unpacking the new wiper blade and familiarizing yourself with its components.
  2. Align the wiper arm: Carefully align the hook-shaped curve of the wiper arm with the curved top end of the new wiper blade.
  3. Attach the wiper blade: Move the hook on the wiper arm over the plastic clip on the new wiper blade. Pull the wiper blade upward until the clip’s edge clicks into place. Ensure that the entire plastic assembly on the new wiper blade is securely attached.
  4. Repeat for the other blade: If you are replacing both front windshield wipers, repeat the same process for the other blade.

Use this table as a general guide to determine the recommended wiper blade size for your car. 

However, it is always recommended to consult your car’s owner’s manual or the manufacturer’s website for precise wiper blade specifications.

How to Test the New Blades

Once you have successfully installed the new wiper blades, it’s important to test their functionality before hitting the road. 

Here’s how to do it:

  1. First, make sure your windshield is wet. You can either spray windshield wiper fluid onto the glass or use a garden hose to wet the windshield.
  2. Next, turn on your car’s wipers. Observe the movement of the blades as they wipe across the windshield. Ensure that the blades are making full contact with the windshield surface without skipping or streaking.
  3. If you notice streaking or skipping, try cleaning the windshield with glass cleaner and a soft cloth. Sometimes residue or dirt on the glass can affect the wiper blade’s performance. If cleaning the windshield doesn’t resolve the issue, you may need to recheck the installation of the blades.


Replacing old windshield wipers is crucial for maintaining safer driving conditions.

Make it a habit to replace your wiper blades at least once a year, or more frequently if you reside in sandy or dusty areas.

Remember, wiper blade maintenance is an essential part of car care. It not only improves your safety but also contributes to the overall longevity and performance of your wipers. So, take the time to check your wipers regularly and replace them when necessary.
