What Are The Common Faults With The Wiper System?

Windscreen wiper systems, while generally reliable, can encounter several common faults over time due to wear and tear, environmental factors, manufacturing defects or installation of the wrong parts. Though it may seem a small part of the car, visibility is key to driving, so if your windscreen wipers were to fail whilst it’s raining, you could find yourself in quite a perilous position.

This article will help you identify some of the more common faults that occur and, if you are looking for a repair service you can trust, then visit WipeWave, the specialists in wiper technology.

What Are The Dangers Of Faulty Wiper Blades?

Faulty wiper blades can pose several dangers to drivers, particularly during adverse weather conditions when visibility is crucial. The following are some of the key risks associated with using worn or damaged wiper blades.

  • Reduced Visibility
    The primary function of wiper blades is to clear rain, snow and debris from the windscreen to maintain clear visibility. Faulty blades may leave streaks or smears, significantly reducing the driver’s ability to see the road, other vehicles, pedestrians and road signs.
  • Distracted Driving
    Struggling with poor visibility due to ineffective wiper blades can lead to driver distraction as the driver may focus more on trying to see through the windscreen than on the road and surrounding environment.
  • Glare
    At night or during low-light conditions, water or debris left on the windscreen by faulty blades can cause light from oncoming vehicles’ headlights or streetlights to scatter, creating glare that can temporarily blind the driver.
  • Increased Risk of Accidents
    Reduced visibility and increased driver distraction elevate the risk of accidents, particularly in challenging conditions like heavy rain, snow or sleet. Even a momentary lapse in concentration or visibility can cause delayed reactions to changes in traffic flow, obstacles or sudden stops.
  • Windscreen Damage
    Worn or damaged wiper blades can cause scratches or other damage to the windscreen over time. This is particularly true for blades where the rubber has worn away, exposing the metal or hard plastic components of the wiper arm, which can then drag across the glass.

Common Windscreen Wiper Faults

When a windscreen wiper fails, it is crucial to get it repaired immediately, especially in the UK where the weather is highly unpredictable. You do not want to be caught in sudden torrential rain whilst flying down the M5 with poor visibility. We’ve all been there, it’s terrifying. Here are some of the most common windscreen wiper faults:

  • Wiper Motor Failure

The motor is what drives the wiper blades across the windshield. If the motor burns out or encounters an electrical fault, the wipers will not work.

  • Worn Blades

Wiper blades are made from rubber that can wear out, split or crack over time, especially due to exposure to sunlight and extreme temperatures. This can lead to streaking, squeaking or inefficient windscreen clearing.

  • Faulty Wiper Linkage

The linkage connects the wiper motor to the wiper arms. If the linkage is bent, broken or disconnected, the wiper arms won’t move as they should if at all.

  • Blown Fuses

A blown fuse can prevent the wiper system from receiving power. Fuses can blow due to overloading, short circuits or ageing.

  • Electrical Problems

Issues with the vehicle’s electrical system, such as faulty wiring or connections can affect the wipers. This may include the control switch, relay or other circuit components.

  • Park Switch Failure

Most wiper systems have a park switch that ensures the wipers return to their resting position when turned off. If this fails, the wipers may stop anywhere on the windscreen.

Get Your Perfect Fit

Regular maintenance and timely replacement of worn parts can help mitigate these issues, and these are things that should be picked up on during your annual MOT. However, if you are experiencing problems with your windscreen wipers then use WipeWave’s registration plate product finder to get the correct parts for your car.
