Windshield wipers that fail to make full contact can be a frustrating issue, especially during inclement weather. To fix this problem, you need to inspect the wiper blades, arms, and linkage. Adjust or replace parts as necessary to ensure the wipers clean the windshield effectively.

Why Are My Windshield Wipers Not Making Full Contact?

When windshield wipers don’t make full contact, it can lead to streaks and reduced visibility. Common causes include:

• Worn-out wiper blades: Over time, the rubber on the wiper blades can degrade, causing uneven contact.
• Bent wiper arms: If the wiper arms are bent, they won’t apply even pressure across the windshield.
• Loose wiper linkage: The mechanism connecting the wiper motor to the arms might be loose, affecting performance.

How to Inspect and Fix Wiper Blades

1. Check the Wiper Blades: Inspect the rubber for cracks or tears. If damaged, replace the blades. New blades ensure even pressure and better contact.
2. Clean the Blades and Windshield: Dirt and debris can prevent proper contact. Use a clean cloth and windshield cleaner to wipe both the blades and the glass.
3. Inspect the Wiper Arms: Ensure the arms are not bent. Gently adjust them if necessary, or replace them if they are severely damaged.

Adjusting the Wiper Arms for Better Contact

• Lift the Wiper Arm: Gently pull the arm away from the windshield.
• Bend the Arm Slightly: If the arm seems bent, carefully bend it back to its original shape. Use pliers if needed, but be cautious to avoid damage.
• Test the Wipers: After adjustments, test the wipers to ensure they make full contact.

Replacing Wiper Blades: A Step-by-Step Guide

Replacing wiper blades is a straightforward process:

1. Lift the Wiper Arm: Pull the arm away from the windshield until it locks in a raised position.
2. Remove the Old Blade: Press the release tab on the blade connector and slide the blade off the arm.
3. Attach the New Blade: Align the new blade with the arm and push it until it clicks into place.
4. Lower the Wiper Arm: Gently lower the arm back onto the windshield.

What If the Wiper Linkage Is Loose?

If the wiper linkage is loose, it can cause the wipers to malfunction. Here’s how to address it:

• Access the Linkage: You may need to remove the cowl (the panel between the hood and windshield) to access the linkage.
• Tighten Any Loose Bolts: Use a wrench to tighten any loose bolts connecting the linkage to the wiper motor and arms.
• Lubricate Moving Parts: Apply a small amount of lubricant to the moving parts to ensure smooth operation.

When to Seek Professional Help

If you’ve tried these solutions and the wipers still aren’t making full contact, it might be time to consult a professional. They can diagnose more complex issues, such as motor problems or electrical faults.
