How to Replace Wiper Blades

Reading Time: 3 minutes

Windshield wipers keep your car’s windshield clear of debris, dirt, or any other elements that make it difficult to see the road. Due to this, it is essential to have properly functioning wiper blades to ensure your safety when operating your vehicle.

It is recommended that you replace your wiper blades at least once a year or when they show signs of wear or damage. It doesn’t take much time or effort to swap out cracked or old wipers for fresh units, so why not DIY and save some money by learning how to change wiper blades?

Wiper blades should be replaced at least once a year or when they start showing signs of wear and damage.

How to Replace Wiper Blades

Each wiper assembly consists of an arm and the wiper blade itself. Typically, you only need to replace the wiper blade.

How to Remove Wiper Blades

  1. Move the wiper assembly arm away from the windshield. Turn the wiper blade perpendicular to the arm.
  2. Now that you have placed the wiper blade in the right position, it’s time to remove it. Look for a release tab under the blade at the spot between the blade’s rubber insert and the metal arm. Push down on the tab while pulling the wiper blade away from the hooked portion of the arm. If you need a visual of how to do this, most wiper blades will have instructions on the back of the package.
  3. Carefully return the wiper arm to its resting position on the windshield to prevent it from snapping back down and hitting the glass. Cushion the arm with a cloth or rag to keep it from scratching the windshield.
  4. Repeat the same process to remove the other windshield wiper blade.

How to Install New Wiper Blades

  1. Remove the new wiper blades from their packaging. Make sure you install the correct blade on the corresponding wiper arm (sometimes the wipers are different lengths).
  2. Raise the arm slated to receive its new wiper blade. Look for the hinge on the blade and move it until the hinge assumes a position perpendicular to the rest of the part.
  3. Align the blade with the wiper arm and guide the arm’s hook inside the blade’s hole. Now, pull the wiper blade up and keep at it until you hear the click of the arm’s hook locking onto the blade.
  4. Lower the windshield wiper to its resting position. Check the wiper’s angle to make sure the blade is correctly installed.
  5. Repeat this process again for the other wiper arm to wrap up the installation process.

How to Test the New Windshield Wipers

Once you’ve finished installing the new windshield wipers or rubber inserts, test them for any problems. Pour wiper fluid over the windshield and run both wipers. They shouldn’t leave any marks as they brush the fluid off the glass.

Sometimes, new windshield wipers can leave streaks on the glass. Soak a cloth in mineral spirits and use it to wipe the rubber insert⁠. You can also use alcohol wipes.

If you still see streaks after cleaning the rubber inserts, check to see if you installed the correct blade on each wiper arm. Make sure that the wiper follows the correct orientation.

Some wiper blade models have blades of different lengths to compensate for their position on the car. Keep this in mind when you search for replacement parts, and measure the lengths of your car’s wipers to serve as a point of comparison for the new wiper blades.
