Windshield wiper noise can be a real annoyance while driving in the rain. That squeaking, chattering, or thumping sound can distract and even obstruct your view. Fortunately, noisy wipers are often a symptom of a simple problem with an easy fix. Let’s explore the common causes and how to silence those noisy wipers.
Common Causes of Loud Windshield Wipers
Several factors contribute to noisy windshield wipers. Identifying the root cause is the first step to resolving the issue.
Worn or Damaged Wiper Blades
The most common culprit of noisy wipers is old or damaged wiper blades. Over time, the rubber edge of the blade can become cracked, torn, or hardened. This prevents the blade from making proper contact with the windshield, leading to chattering or squeaking sounds. Wiper blades typically need to be replaced every six to twelve months.
Dirty Wiper Blades
Even relatively new wiper blades can become noisy if they’re dirty. Road grime, bugs, and tree sap can build up on the blades, hindering their ability to cleanly wipe the windshield. This buildup can cause a skipping or thumping sound.
Dirty Windshield
A dirty windshield can also contribute to wiper noise. Wax residue, oil, and other contaminants can create a rough surface that the wiper blades struggle to glide across. This often results in a squeaking or chattering noise.
Weak Wiper Arm Spring
In older cars, the spring in the wiper arm can weaken over time. This reduces the pressure the blade applies to the windshield, causing it to chatter or skip.
Incorrect Wiper Blade Angle
If the wiper blade isn’t perpendicular to the windshield, it can create uneven pressure and lead to chattering. A slight adjustment to the blade angle might be all that’s needed.
Solutions for Noisy Windshield Wipers
Once you’ve identified the likely cause of the noise, you can take steps to fix it.
Replace Wiper Blades
If your wiper blades are worn, damaged, or over a year old, replacing them is the best solution. New blades provide a clean, smooth wipe and eliminate most noise issues.
Clean Wiper Blades and Windshield
Thoroughly cleaning your wiper blades and windshield can often resolve noise problems. Use a clean cloth and glass cleaner to remove dirt and grime from both surfaces. You can also use rubbing alcohol to clean the wiper blades.
Adjust Wiper Arm Tension
If you suspect a weak wiper arm spring, you may be able to adjust the tension. Consult your car’s owner’s manual for instructions on how to do this.
Adjust Wiper Blade Angle
Carefully examine the angle of the wiper blade against the windshield. If it’s not perpendicular, gently bend the arm to adjust the angle.
Conclusion
Loud windshield wipers are a common problem with relatively simple solutions. By addressing the underlying causes, you can enjoy a quiet and clear view while driving in the rain. Regular maintenance, including cleaning and replacing wiper blades, can prevent future noise issues. If the problem persists after trying these solutions, it’s best to consult a qualified mechanic.
