wiper linkage replacement

What does a wiper linkage do?

The wiper linkage is the component that attaches the windscreen wiper motor to the wiper arms and blades. Its job is to transmit the motion of the wiper motor to the wiper arms and blades to clear rain, snow and ice from your windscreen. This component is an important safety feature as it plays a key role in ensuring the driver has good visibility at all times.

How often should a wiper linkage need replacing?

The wiper linkage on your car should last its lifetime, however this will depend on the driving conditions, how often your wipers are used and the quality of the parts. Be sure to have your wiper system checked if you notice any of the above symptoms and make sure you turn your wipers on regularly, even in summer, to avoid the linkage seizing up.

The law, vehicle regulations and your MOT

A broken or faulty wiper linkage is both dangerous and illegal on UK roads. The unpredictable weather in this country means that drivers rely on their windscreen wipers to provide much needed visibility in rainy weather, without which they would be a danger on the roads. The wiper system is also thoroughly checked during the MOT and any fault or malfunction will result in an MOT failure.

What causes a wiper linkage to break?

The wiper linkage is attached to the wiper motor, which is usually located under the hood of the vehicle and is protected from the elements. However, because the linkage is often exposed to the sun, snow, wind, and rain it is more susceptible to wear and tear or breaking entirely without warning. One of the most common causes of premature wear is overuse in rainy climates or in cold temperatures where the windshield wipers are frozen and may stick to the windshield. This sticking causes the linkage to strip from the wiper arm, requiring a replacement to be fitted.

When should a wiper linkage be replaced?

The windshield wiper linkage is designed to last the lifetime of the vehicle, but like any other mechanical part it can break or malfunction when you least expect it. As soon as you begin to notice your wipers struggling to move across the windscreen, making strange noises or moving out of sync, you should have your wiper system, including the linkage, looked at by a mechanic and replaced.

Fully functioning wipers are a key safety feature in your car so it’s vital that you get them fixed as soon as you notice a problem.
