Parts for your 2020 Mazda 3-Wiper blades

2020 Mazda 3 wiper-blades: purpose, fitment and easy upkeep

Wiper-blades absolutely are fitted to the 2020 Mazda 3 and are essential to safe driving. This is confirmed in Mazda’s 2020 Mazda3 (BP series) Owner’s Manual, the Mazda Workshop Manual, and the Mazda Genuine Parts Catalogue, all of which list front windscreen wipers (and, on hatch variants, a rear wiper-blade). So, wiper-blades are relevant for every 2020 Mazda 3 on Australian and New Zealand roads.

On this model, the wiper-blades are low-profile, beam-style units designed to sweep water, road grime, salt spray and insect residue off the glass to keep vision clear. In local conditions—summer UV, coastal air, and winter frosts—rubber can harden or crack sooner, so it pays to check them regularly. As part of routine servicing (typically every 10,000–15,000 km or 12 months, depending on the schedule), a quick inspection and clean keeps them working sweet as.

Owners will usually see common fitments around 650 mm for the driver’s side and 400 mm for the passenger side, hatch variants also carry a rear blade of roughly 300 mm. Exact sizing can vary by trim and market, so it’s smart to confirm against the Owner’s Manual or the part lookup at time of purchase. Most quality aftermarket blades come with the correct top-lock style adapter for the Mazda 3 BP arms.

When it’s time to replace, look for tell-tales like streaking, chattering, missed patches, frayed edges, or squeaks. If any of those show up—even after cleaning—the rubbers are likely done. In the Mazda 3 BP, it’s easiest to enter the wiper Service Position (via the stalk after switching the vehicle off), then lift the arms away from the glass. Swap the blades like-for-like, making sure the adapter clicks firmly into place, then lower the arms gently.

• Clean the rubbers monthly with a damp cloth and a dab of washer fluid.
• Top up with proper windscreen wash, avoid plain water where possible.
• Never run wipers on a dry, dusty screen—mist the glass first.
• In frost, free the blades before switching wipers on to protect the motor.
• Plan on replacing every 6–12 months in AU/NZ conditions, or sooner if worn.

Done right, fresh wiper-blades make night drives in the rain far less stressful and help the Mazda 3’s safety tech see clearly, too.

Popular questions

What size wiper-blades fit a 2020 Mazda 3?
Most 2020 Mazda 3 BP models take a driver blade around 650 mm and a passenger blade around 400 mm. Hatchbacks usually add a rear blade close to 300 mm. Because sizes can vary by body style and region, it’s best to confirm against the Owner’s Manual or the original blades before buying.

How often should 2020 Mazda 3 wiper-blades be replaced in Australia or New Zealand?
A good rule is every 6–12 months, or at the first sign of streaking, squeaking, or judder. Harsh sun, coastal air and winter chills can age rubber faster here, so quick monthly cleans and checks at each service help extend life.

Does the 2020 Mazda 3 sedan have a rear wiper-blade?
No. The rear wiper-blade is fitted to hatch variants, sedans do not have a rear wiper. If buying a rear blade, make sure the vehicle is the hatch body style.
