Fixing windshield wiper alignment is an essential maintenance task that ensures your wipers function effectively, providing clear visibility during rain or snow. Misaligned wipers can cause streaks, noise, and even damage to your windshield. Fortunately, adjusting them is a straightforward process that you can do yourself with minimal tools.

How Do You Fix Windshield Wiper Alignment?

To fix windshield wiper alignment, first park your car on a level surface and turn off the ignition. Lift the wiper arms from the windshield and inspect the blades for wear. Loosen the wiper arm nut, adjust the arm to the correct position, and then retighten the nut. Test the alignment by turning the wipers on to ensure they move smoothly without leaving streaks.

Why Is Windshield Wiper Alignment Important?

• Effective Cleaning: Wipers that are correctly aligned make full contact with the windshield, effectively removing rain, snow, or debris.
• Reduced Noise: Misaligned wipers can cause annoying squeaking or chattering noises.
• Prevention of Damage: Proper alignment prevents the wipers from hitting the windshield trim or overlapping, which can cause damage.

What Tools Do You Need to Adjust Windshield Wipers?

Before you begin adjusting your windshield wipers, gather the following tools:

• Socket Wrench: For loosening and tightening the wiper arm nut.
• Screwdriver: May be needed for specific wiper models.
• Marker or Tape: To mark the correct alignment position on the windshield.
