Dealing with Malfunctioning Windshield Wipers: A Comprehensive Guide

Your windshield wipers are unsung heroes during adverse weather conditions. They ensure you maintain visibility during rain, sleet, or snow, making them crucial for safe driving. But what happens when they start acting up? Malfunctioning windshield wipers can be a hassle, but with the right knowledge, you can tackle the issue head-on.

Understanding the Importance of Windshield Wipers

Windshield wipers play a pivotal role in ensuring clear vision while driving. They remove rain, snow, dirt, and debris, enhancing visibility and safety. Given their constant exposure to environmental elements, it’s not surprising that they can wear out or malfunction.

Common Windshield Wiper Malfunctions and Their Causes

1. Streaking or Skipping Across the Windshield

This is often due to worn-out wiper blades. Over time, blades can harden and crack, causing them to miss spots or leave streaks.

2. Squeaking or Chattering Sounds

If your wipers make a squeaky noise, it can be due to dirty or misaligned blades. This noise not only is annoying but also indicates that your wipers aren’t making proper contact with the windshield.

3. Wipers Moving Slower Than Usual

This could result from a malfunctioning wiper motor or issues with the linkage connected to the motor.

4. Wipers Not Moving At All

If your wipers aren’t moving, it’s often a sign of a burnt-out motor, blown fuse, or broken linkage.

Fixing Malfunctioning Windshield Wipers

1. Replacing Wiper Blades

If you notice streaks or skipped areas, your wiper blades likely need replacement. Most manufacturers recommend changing them every 6-12 months. When buying replacements, ensure they are the correct size and compatible with your vehicle.

2. Cleaning the Wiper Blades

Dirt, grime, or tree sap on the blades can cause squeaking. You can clean them using a cloth dipped in a mixture of water and a few drops of dish soap.

3. Checking the Fuse and Motor

If your wipers aren’t moving, inspect the fuse. A blown fuse can easily be replaced. If the fuse is intact, the issue might be with the motor, which might require professional intervention.

4. Inspecting the Linkage

If your wipers move erratically or not at all, and the motor is working fine, there might be a problem with the linkage. If the linkage is disconnected or broken, it will need to be repaired or replaced.

5. Adjusting Wiper Arm Tension

A loose wiper arm can cause the blade to lift off the windshield, reducing effectiveness. You can gently bend the arm to adjust the tension, ensuring the blade sits snugly against the glass.

Maintaining Your Windshield Wipers

Proper maintenance can prolong the life of your wipers and reduce the risk of malfunction:

Clean Your Windshield Regularly: A clean windshield reduces wear and tear on the wiper blades.
Avoid Using Wipers on Dry Glass: This can cause premature wear. If necessary, use the windshield washer function to provide some lubrication.
Inspect Wipers Periodically: Look for signs of wear, cracking, or damage and replace them as needed.
Avoid Ice Build-Up: In colder months, ensure your windshield and wipers are free of ice before using them.

Conclusion

A clear line of sight is critical for safe driving, and your windshield wipers play a vital role in ensuring this. Regular maintenance and prompt attention to any issues can keep them in optimal condition, safeguarding your visibility in all weather conditions.
