Step 1: Determine the Correct Wiper Blade Sizes
Ensuring the correct size of wiper blades is crucial for optimal visibility and safety. Incorrect blade sizes can either leave parts of your windshield uncleared or scratch the glass. Typically, the driver's side and passenger's side wipers are of different sizes. To find the appropriate sizes:
- Consult Your Vehicle’s Manual: This will provide the manufacturer's recommended sizes for both sides.
- Use an Online Size Finder: Many automotive websites offer tools to help determine the correct size by entering your vehicle’s make, model, and year.
- Measure the Existing Blades: Use a tape measure to determine the length of the current blades.
Step 2: Lift the Wiper Arms
Before removing the old blades, you need to lift the wiper arms:
- Locate the Wiper Arms: These are typically positioned at the base of your windshield.
- Lift the Arms: Gently lift the wiper arms until they are perpendicular to the windshield. Most wiper arms will hold this position on their own.
- Protect Your Windshield: Place a towel under the wiper arm to prevent any accidental damage in case the arm snaps back.
Step 3: Remove the Old Wiper Blades
The method to remove the old wiper blades depends on the type of connectors your vehicle uses. Common types include the J-Hook, Pin Arm, and Bayonet.
For J-Hook Connectors:
- Locate the Release Tab: This is usually on the underside of the wiper blade.
- Press the Tab: This will unlock the blade from the arm.
- Slide the Blade Downward: It should easily come off the hook.
For Pin Arm Connectors:
- Locate the Pin: It secures the blade to the arm.
- Press or Pull the Pin: Depending on the design, either press or pull to release the blade.
- Slide the Blade Off: Remove it from the arm.
For Bayonet Connectors:
- Press the Locking Mechanism: Typically a small button or tab.
- Slide the Blade Off: Once unlocked, the blade will slide off easily.
Always compare the new blade to the old one to ensure the correct size and attachment design before proceeding.
Step 4: Install the New Wiper Blades
Installing new wiper blades is the reverse process of removal:
- Remove Plastic Protectors: Many new wiper blades come with plastic protectors on the rubber part. Ensure these are removed.
- Attach the New Blade: Align the new blade with the arm and slide it into place until you hear a click indicating it is secure.
- Check Alignment: Ensure the blade is parallel to the windshield and not twisted.
- Repeat for the Other Blade: Follow the same steps for the second blade.
- Lower the Wiper Arms: Gently lower the arms back onto the windshield.
Step 5: Test the New Wiper Blades
After installation, testing the new blades is essential to ensure they work correctly:
- Clean the Windshield: A clean windshield helps identify any issues with the new blades.
- Spray Washer Fluid: Apply washer fluid to lubricate the windshield.
- Operate the Wipers: Turn on the wipers at different speeds to ensure they function smoothly without streaking or making noise.
- Check for Issues: If you notice streaks or hear squeaking, double-check the installation or consider replacing the blades.
Common Mistakes to Avoid
- Incorrect Blade Size: Double-check the size to avoid improper clearing or potential damage.
- Forgetting to Remove Protectors: Ensure all plastic protectors are removed from the new blades.
- Dropping the Wiper Arm: Be cautious to avoid letting the arm snap back and damage the windshield.
- Incomplete Installation: Make sure the blade clicks securely into place.
- Skipping the Test: Always test the wipers before driving to ensure they work correctly.
