Wiper Blade - JAX Service Inclusion


What are Wiper Blades and why are they important?

When it comes to window wipers, most drivers don’t spare a thought for them until such time as they aren’t working as they should. While wipers may not seem like a critical car component, the function they perform is arguably one of the most important of all. Without properly functioning wipers on your vehicle, you lose proper vision of the road and any obstacles ahead. Needless to say, this can increase your risk of accidents and of causing harm to yourself, your passengers or others on the road.

But how do you really know whether your wipers are working optimally or not? How do you check them for damage? What are the wiper blades made up of? Why is it important to understand the ins and outs of this crucial car component?

In this article, we're diving into all things window wipers. From your common questions and concerns, recommended maintenance and replacement, and what to keep a lookout for when it comes to faulty or aging wipers - we’ve got you covered.

What are window wiper blades exactly?

Windshield wiper blades are responsible for keeping our front and rear view vision clear. By moving back and forth across your windscreen, the wipers clear rain, snow, debris and wiper fluid from the windscreen glass.

There are a few different types of wiper blades available: conventional, flat and hybrid. Up until recently, most cars were fitted with conventional blades but flat blades are becoming more and more common on new cars.

Different types of window wiper blades

The following types of blades are commonly found:

Conventional blades

Conventional blades are usually made up of metal or a plastic metal composite. There are varying pressure points distributed along the length of the blade (or central bridge as it is technically known as). Spring flexors balance out the pressure created by the wiper arm to create an even force when the blade wipes across the glass.

Beam wiper blades

Unlike conventional blades that have six to eight pressure points along the blade, beam wiper blades have an infinite number of pressure points. This means the entire blade remains in contact with the screen while wiping.

Windscreen wiper parts:

A windscreen or windshield wiper is made up of a number of different parts including:

  • Windscreen wiper arm. The arm creates movement from the wiper motor to the wiper.
  • Connectors secure the wiper blade to the wiper arm.
  • Spring flexors distribute even pressure across the blade onto the glass.
  • Rubber element allows the flexibility that the blade needs in order to move in and out of different angles.
  • Spoiler is located on the driver’s side to ensure the wiper blade maintains contact with the screen at all times - even at high speeds.

Wiper blades and professional vehicle servicing

The life of your window wipers could be anywhere between 6 months and 2 years depending on the quality. As a function that is used regularly wipers are more susceptible to wear and tear than other car components. But, as a relatively small part of your vehicle, wiper maintenance often slips under the radar - that is until you experience a problem with them functioning as you need them to on the road.

For peace of mind and to spot potential problems early we recommend booking your car in for regular professional vehicle servicing. During this service a qualified mechanic will check the operation of your wipers and look for any possible issues. If it’s been a while between check ups, reach out to your local JAX Mechanics to book in a service today.

Should you lubricate wiper blades?

The short answer is yes, you can lubricate your wiper blades but, keep in mind it is a short term solution and not every type of lubrication will be safe or suitable for your wipers.

If your wipers are squeaky or are leaving your windscreen streaky, lubrication could be a temporary answer until you are able to get to your local mechanic. To lubricate your wiper blades carefully wipe them down with soap, water and an old rag.

Allow them to dry for roughly 20 minutes then spray with silicone lubricant (available at most auto stores) and wipe dry. The lubricant acts to reduce squeaking and allows them to smoothly move across the windscreen.

Can you drive with broken wipers?

No you can not drive with broken wipers.

Australian Government Vehicle Standard Safety requirements state that any motor vehicle with a windscreen must be fitted with a working, power-driven windscreen wiping system. Your car could be classed as unroadworthy and illegal if any your wipers are:

  • Not secure
  • Worn down
  • Missing any components
  • Unable to operate at all settings and speeds
  • Restricting driver vision

This is not an exhaustive list and you may face fines or penalties if you are found to be driving with defective wipers. For this reason, we always recommend you visit your local mechanic if your wipers aren’t working as they should.

NOTE: The above relates to front window wipers not rear wipers. There is no legal requirement for rear vision wipers to be operational. However, anything impacting your vision while driving should be considered a safety hazard and should be fixed promptly.

Why do my wiper blades squeak?

Squeaky window wipers can be loud, distracting and annoying, but it’s more than that.

If your wipers are making unusual noises it could mean one of three things:

  1. Your windscreen and/ or wipers are dirty and need to be cleaned.
  2. Your wipers are in need of lubrication.
  3. Your wiper blades are broken and need one or more components replaced in order to work properly.

In any of these cases it’s important to rectify squeaky wipers quickly so that your vision isn’t impaired while you’re on the road.

How do I know when my wiper blades need replacing?

Wiper blades have a lifespan of 12 - 24 months. However, this time can be reduced if they’re over-exposed to lots of sun, mud, ice, snow or excess rain. If you notice any of the following, it may mean your wipers need to be replaced sooner:

  • Squeaking sounds indicate that wiper blades are either worn out or are in need of a clean and service.
  • Streaking on the glass is a key indicator that your wipers aren’t functioning as they should. Not to mention, streaking glass can restrict your vision and risk safety while driving.
  • Vibrating wipers often means there is an uneven connection between the wiper blade and the windshield. This could mean one wiper component or an entire blade needs to be replaced.
How often should my windscreen wipers be checked?

Window wipers should be replaced every 12-24 months or as soon as you notice they aren’t working as they should. Signs your wipers aren’t functioning properly include:

  1. Squeaking
  2. Streaking
  3. Vibrating

How do I know which wiper blades to buy?

There is no one-size-fits-all when it comes to window wipers. The type you need will totally depend on your car and unique driving requirements. Unless you’re an experienced mechanic it’s best to get the advice of a professional when it comes to wiper blade selection. Here are some factors to consider when weighing up different types of wipers:

  • Check your manual. This will tell you what size and type of blades you need. In some cases, your manual may recommend a particular brand that is best suited to your car.
  • The length of the wiper blades must fit your car.
  • Do the aesthetics of the blade match your vehicle?
  • Do the wipers come with warranty?
  • What type of wiper connector does it have - will it fit on your car?
