Windscreen Wipers – What Every Driver Should Know

When the heavens open, your wipers are the first line of defense. A good set clears water, mud, and spray so you can see the road and stay in control. This page brings together the most useful tips on blade size, safety, pricing, and upkeep, so you can pick the right wipers and avoid costly mistakes.

Pick the Right Blade Size

Most cars come with either a 16‑inch or a 17‑inch blade on the driver’s side, but you’ll see other lengths on the passenger side. Swapping a 16‑inch blade for a 17‑inch piece might give a little extra coverage, but it can also rub the windshield edge or cause a noisy wobble. Check the factory label on the existing blade or the owner’s manual to confirm the exact length. If you’re unsure, measure from the pivot point to the tip of the rubber.

When you buy a new set, match each side’s specified size. Using the wrong size on one side can create uneven wiping, leaving streaks that reduce visibility. Most retailers list the correct size right on the packaging, so a quick glance saves you a bad install.

Stay Safe When Wipers Fail

Driving with broken or stuck wipers isn’t just uncomfortable—it can be illegal in many regions, including New Zealand. The law requires functional wipers in wet conditions, and police can issue fines if you’re caught. Besides the legal risk, a failed wiper can hide potholes, road markings, and other hazards, increasing the chance of an accident.

If a blade stops moving, first check the fuse and the wiper motor. A simple jam caused by debris is often fixed by cleaning the mechanism. If the motor hums but the blade doesn’t move, the linkage might need lubrication or replacement. In any case, don’t ignore the problem; a quick shop visit or DIY fix can keep you safe and out of trouble.

For those rainy days when the blades are still functional but leaving streaks, a short spray of windshield washer fluid followed by a quick wipe with a clean cloth can improve visibility until you get a fresh set.

Where to Find the Best Prices

Wiper blades are cheap, but the price can vary a lot between stores. A typical 16‑inch blade costs around $15 at big‑box retailers, while a premium silicone blade can run $30 or more. Comparing AutoZone and Walmart in 2025 showed a $3‑$5 difference for most brands, with Walmart often offering the lowest price on bulk packs.

Don’t forget to factor in shipping if you shop online. Free in‑store pickup can shave a few dollars off the total, and many stores run seasonal sales in spring when demand spikes. Keep an eye on clearance aisles – you’ll often find high‑quality blades at a fraction of the regular price.

Finally, consider buying a set that includes both driver and passenger blades. Bundles usually save a few bucks and ensure you have matching blades for even performance.

Regularly inspect your wipers for cracks, hardened rubber, or loosened clips. Replacing them every 12‑18 months keeps wiping efficiency high and prevents squeaks. With the right size, a quick safety check, and a smart purchase, you’ll stay clear‑sighted and legal all year long.
