How To Change Wiper Blades

Replacing Wiper Blades

Replacing your wiper blades is simple and can be done in just a few minutes. Follow these general steps to install new wiper blades on your vehicle.

Step 1: Determine the Correct Blade Size

• Check your vehicle’s owner’s manual or search for the correct size online. Most auto parts stores have a book that you can use to reference your vehicle's year, make, and model to find the correct part(s).
• Some vehicles have different sizes for the driver and passenger sides, so ensure you purchase the correct length.

Step 2: Lift the Wiper Arms

• Gently pull the wiper arms away from the windshield until they lock in the upright position.
• Be cautious—if they snap back down, they can crack your windshield. It's a good idea to place something like cardboard or a towel on the windshield in case they do snap down.

Step 3: Remove the Old Wiper Blades

The removal process depends on the type of wiper arm mount. Follow the specific instructions for your mount type:

Hook (J-Hook) Mount:

• Locate the small tab on the underside of the wiper blade near the hook.
• Press the tab and slide the old wiper blade downward, disengaging it from the hook.
• Once detached, slide the blade off the hook and discard it.

Pin-Based Mounts (Side Pin, Top Lock):

• Locate the push button or pin release mechanism.
• Press the button while gently pulling the blade away from the arm.
• The blade should slide off easily.

Bayonet and Slim Top Mounts:

• Find the locking clip on the blade.
• Press the clip while pulling the blade outward from the arm slot.
• Once free, slide the old blade off completely.

Screw and Claw Mounts:

• Use a small screwdriver to remove the screw securing the blade.
• If using a claw mount, carefully pry the old blade loose.
• Remove the blade gently to avoid damaging the wiper arm.

Step 4: Attach the New Wiper Blades

• Align the new blade’s connector with the wiper arm.
• Follow the reverse of the removal steps to attach it securely.
• Listen for a “click” to confirm it’s locked in place.

Step 5: Test the Wipers

• Lower the wiper arms back onto the windshield.
• Start your car and activate the wipers to ensure they move smoothly and clean the windshield without streaking.
• If the blades are not secured correctly, they may detach or leave streaks.

Remember: Replace Both Wipers Together

Even if only one blade needs replacing, it's best to replace both simultaneously for better performance and visibility.

Prolonging Wiper Blade Lifespan

Protecting your vehicle can extend the life of your wiper blades:

• Use of Car Covers: Shielding your vehicle from the elements reduces exposure to sunlight and debris, which can degrade wiper blades. Find yours with our cover finder.
• Regular Cleaning: Wipe the blades and windshield regularly to remove dirt and prevent abrasion.
• Avoid Using Wipers on Ice: To clear frost, use an ice scraper instead of wipers, which will prevent damage to the rubber.

By following these practices, you can enhance the performance and longevity of your wiper blades, ensuring safer driving conditions and saving money over time.

Inspecting Wiper Blades for Wear

Regular inspection of your wiper blades can prevent streaking and maintain optimal performance. Here's how to assess their condition:

Visual Examination: Lift the wiper arm away from the windshield and inspect the rubber squeegee for:

• Cracks or Tears: Visible splits in the rubber.
• Rounded Edges: The wiping edge should be sharp; rounded edges indicate wear.
• Flexibility: Ensure the rubber is supple, not brittle.

Performance Test: During operation, watch for:

• Streaking: Lines of water left on the windshield.
• Skipping or Chattering: Blades jumping or making noise during movement.
• Incomplete Contact: Areas of the windshield remain unwiped.

If any of these signs are present, it's time to replace your wiper blades.

Understanding Wiper Arm Mount Types

Wiper blades attach to wiper arms using various mounting systems. Identifying your vehicle's mount type is crucial for proper replacement. Below are common mount types, grouped by their similarities:

1. Hook Mounts

Description: Features a curved, hook-shaped end on the wiper arm.

Types:

U-Hook (J-Hook): A prevalent design where the blade slides into the hook and locks in place.

Replacement Tips:

• Ensure the new blade's connector matches the hook size (commonly 9mm or 12mm).
• Listen for a click to confirm a secure attachment.

2. Pin-Based Mounts

Description: Utilize a pin mechanism to secure the blade.

Types:

Side Pin: A pin protrudes from the side of the arm, fitting into the blade.

Top Lock (Push Button): A pin on the top of the arm locks into the blade via a push-button release.

Replacement Tips:

• Align the blade's hole with the pin accurately.
• Depress the release button when removing the old blade.

3. Bayonet and Slim Top Mounts

Description: Feature a flat, slender arm that slides into the blade's connector.

Types:

Bayonet Arm: The arm slides into a slot on the blade and locks with a clip.

Slim Top Lock: A compact bayonet version, often with a top-mounted release button.

Replacement Tips:

• Slide the blade onto the arm until it locks securely.
• Verify compatibility with the arm's width and thickness.

4. Screw and Claw Mounts

Description: Less common; involves additional fastening methods.

Types:

Screw Mount: The blade is secured to the arm using a screw.

Claw Mount: The arm has claws that grip the blade.

Replacement Tips:

• Ensure screws are appropriately tight to avoid loosening.
• Align claws properly to prevent blade detachment.
