Adjusting windshield wipers that are hitting each other is a straightforward process that can prevent damage and improve visibility while driving. This issue typically arises from improper alignment or wear and tear over time. By following a few simple steps, you can ensure your wipers function smoothly and efficiently.
Why Do Windshield Wipers Hit Each Other?
Windshield wipers may collide due to misalignment, which can occur from incorrect installation, loose components, or bent wiper arms. Over time, wear and tear can also cause the wipers to shift from their original positions.
Common Causes of Wiper Misalignment
- Improper Installation: If wipers are not installed correctly, they may not move in the intended path.
- Loose Components: Nuts and bolts securing the wiper arms might loosen over time, leading to misalignment.
- Bent Wiper Arms: Physical damage or excessive force can bend the arms, altering their path.
How to Adjust Windshield Wipers
Step-by-Step Guide to Fix Wipers
-
Inspect the Wipers: Check for visible damage or wear on the blades and arms. Replace any damaged parts.
-
Align the Wiper Arms:
- Turn off the wipers and ensure they are in the "parked" position.
- Gently lift the wiper arms away from the windshield.
- Loosen the nuts at the base of the wiper arms using a wrench.
- Adjust the arms to the correct position, ensuring they are parallel and do not overlap.
- Tighten the nuts securely.
-
Test the Wipers:
- Turn on the wipers to check their movement.
- Ensure they clear the windshield without hitting each other.
-
Adjust Again if Necessary:
- If the wipers still collide, repeat the adjustment process.
- Consider checking for any underlying issues like bent wiper arms.
Tools Needed for Adjustment
- Wrench or socket set
- Replacement wiper blades (if necessary)
- Cleaning cloth
Preventing Future Wiper Issues
- Regular Maintenance: Periodically check the alignment and condition of your wipers.
- Replace Wiper Blades: Change blades every 6-12 months or when they show signs of wear.
- Protect from Damage: Avoid using wipers to clear heavy snow or ice, which can bend the arms.
Practical Example
Suppose your car’s wipers start hitting each other after a heavy snowfall. You inspect them and find one of the arms slightly bent. By following the adjustment steps, you realign the arms and ensure they function correctly, preventing further damage.
