Common Windscreen Wiper Problems and How to Fix Them

Windscreen wipers play a vital role in vehicle safety by ensuring clear visibility during rain, fog, and snow. Many drivers overlook the health of their wiper blades until they fail to perform during crucial moments. Damaged or poorly functioning wipers can severely compromise visibility, increasing the risk of accidents. 

High-quality Car Windscreen Wipers ensure clear visibility during rain, fog, or snow, keeping your drive safe and stress-free. Built with durable materials, they provide smooth, streak-free wiping action. Investing in premium wipers enhances performance, lasts longer, and protects you from unexpected weather challenges on the road.

Understanding the common problems associated with windscreen wipers and learning how to fix them can help extend their lifespan, improve performance, and ensure safer driving conditions. This article explores the most frequent issues drivers face with their wipers and practical solutions to resolve them effectively.

Wipers Leaving Streaks on the Windscreen

One of the most frequently encountered problems is streaking. When wipers leave streaks on the glass, the visibility becomes blurred and unsafe, especially during heavy rainfall. Streaking usually indicates worn-out rubber or dirt buildup on the blades or the windscreen. Over time, the rubber edge hardens and loses flexibility, preventing smooth contact with the glass surface. To fix this issue, thoroughly clean both the windscreen and the wiper blades using a cloth soaked in glass cleaner or mild soap solution. If the streaking persists after cleaning, it may be time to replace the blades entirely. Regular cleaning and timely replacement are the best ways to prevent streaking.

Wipers Skipping Across the Windscreen Surface

Skipping occurs when the wipers bounce or hop across the windscreen instead of gliding smoothly. This problem can result from several factors, such as damaged wiper arms, bent frames, or aged rubber blades. Another common cause is a dry or dirty windscreen, which reduces surface lubrication. To fix skipping, start by cleaning the windscreen thoroughly and checking that the rubber blade is soft and intact. If the blade has hardened or cracked, replacement is necessary. Also inspect the wiper arms to ensure they are properly aligned and applying even pressure. Adjusting or straightening a bent arm can quickly restore normal function.

Wipers Making Squeaking or Chattering Noises

Squeaking and chattering sounds are not only annoying but also indicate improper blade contact or excessive friction. This issue usually arises when the blades are dry, dirty, or worn out. Sometimes, environmental factors such as freezing temperatures or heat exposure can lead to rubber hardening, causing noise during operation. To fix this, clean the blades and windscreen to remove dust and debris. Check if the blades have lost flexibility and replace them if necessary. Using a quality windscreen washer fluid also helps reduce friction and noise. If noise continues after cleaning and replacement, check the wiper arm tension, as loose or tight arms can also cause chatter.

Wipers Not Moving or Stopping Mid-Swipe

Another common wiper issue is when the blades stop moving entirely or freeze mid-swipe. This typically indicates a problem with the wiper motor, a blown fuse, or an electrical connection failure. Mechanical obstruction or wiper linkage damage can also lead to malfunction. To resolve this issue, start by checking the fuse box and replace any blown fuse related to the wiper system. Inspect wiring connections for corrosion or loose plugs. If these components are functioning properly, the wiper motor or linkage may need repair or replacement. Since electrical and mechanical repairs can be complex, it is advisable to consult a professional mechanic if the problem persists.

Wipers Smearing Water Instead of Clearing It

Smearing occurs when the blades fail to clear water evenly, leaving large wet patches behind. This problem is often caused by old or damaged blades, incorrect blade size, or oily residue on the windscreen. Road grime, wax, tree sap, and windshield washer fluid residue can create a film that prevents full contact between the blade and the glass. Cleaning the windscreen with an alcohol-based cleaner helps remove stubborn residues. If smearing continues, replace the blades with the correct size for your vehicle model. High-quality silicone blades may also provide longer-lasting performance and improved clarity.

Uneven Wiper Movement or Juddering

Juddering occurs when the blades move unevenly in a jerking motion instead of smoothly. This issue often results from bent wiper arms or incorrect installation. Cold weather can also cause rubber stiffening, reducing flexibility and causing uneven movement. To fix juddering, start by inspecting the wiper arms for bending or misalignment. Gently straighten them if necessary. Make sure the blades are properly installed and compatible with your wiper system. Heating your windscreen before operation during winter can help improve blade performance. If the problem continues, it may indicate worn suspension in the wiper linkage, requiring professional attention.

Washer Fluid Not Spraying Properly

Sometimes, the wiper blades themselves may work fine, but the washer fluid fails to spray effectively, making it difficult to clean the windscreen. This problem is commonly caused by clogged nozzles, low washer fluid levels, or a faulty washer pump. To fix this issue, check and refill the washer fluid reservoir if needed. Clean the spray nozzles using a needle or pin to remove dirt blocking the openings. If fluid still does not spray, inspect the washer pump and hoses for leaks. Replacing a malfunctioning pump may be necessary if no fluid reaches the windscreen despite troubleshooting.

Wipers Moving Too Slowly or Too Fast

A change in wiper speed can indicate an issue with the wiper motor or control switch. Slow wiper movement is commonly caused by motor wear, low electrical power, or mechanical resistance in the wiper linkage. If the wipers move faster than normal unexpectedly, it may be due to faulty wiring or switch malfunction. To fix speed-related problems, inspect the motor and linkage for wear and lubrication issues. Clean electrical connections and check battery or alternator output if power seems low. When wiring or switch problems are suspected, professional diagnosis is recommended to prevent further electrical damage.

Rear Windscreen Wipers Not Working

Rear wipers are often neglected compared to front wipers, yet they are crucial for visibility in hatchbacks and SUVs. When a rear wiper stops working, it may be due to a blown fuse, wiring damage, or a faulty motor. Dirt buildup around the pivot point can also cause the arm to jam. Cleaning the base of the wiper arm and ensuring free rotation can resolve minor issues. If cleaning does not help, check the fuse and wiring. Replacing the motor may be required if electrical issues are ruled out.

Preventing Windscreen Wiper Problems Before They Occur

Proper maintenance is key to preventing most wiper issues. Cleaning both the wiper blades and windscreen regularly reduces wear and extends blade life. Inspecting wipers monthly ensures early detection of cracks, stiffness, or broken frames. Replacing blades every six to twelve months is recommended based on usage and climate. Avoid operating wipers on a dry windscreen, and always use a quality washer fluid to maintain blade lubrication and glass clarity. Parking in shaded or covered areas helps protect blades from harsh UV exposure, prolonging their effectiveness.

Conclusion

Windscreen wipers are simple yet essential components that ensure safe driving conditions in adverse weather. Ignoring early signs of malfunction can result in hazardous visibility issues and expensive repairs. Fortunately, many common wiper problems have straightforward solutions involving cleaning, adjustment, or timely replacement. Regular maintenance and attention to performance can significantly improve wiper efficiency and durability. Whether dealing with streaking, skipping, noise, or mechanical failure, understanding the cause and taking action promptly can help prevent breakdowns at critical moments. Clear visibility is vital for road safety, and maintaining healthy wipers is an easy but crucial responsibility for every driver.
