Rear Windscreen Wiper: When to Replace and How to Do It Right

Ever wonder why the rear glass looks streaky after a rain? Chances are your rear windscreen wiper is on its last legs. A failing wiper can hide spots, blur your view, and make parking a nightmare. In this guide we’ll show you the tell‑tale signs, walk you through a DIY swap, and share simple upkeep tricks so you never get caught off guard.

Spotting a Bad Rear Wiper

First thing’s first – know when the wiper needs attention. If the blade leaves long smears, squeaks loudly, or skips sections altogether, it’s time to act. Also, check the rubber. If it’s cracked, torn, or feels hard to the touch, that’s a clear red flag. Some drivers notice a slower wiping speed; the motor could be losing power, but most often the blade is just worn out.

Another easy test: pull the wiper arm gently away from the glass. It should sit flat without wobbling. Any wobble means the arm or the mounting nut is loose, which can damage the blade faster. Spot these issues early and you’ll avoid costly glass damage later.

DIY Rear Wiper Replacement – Step by Step

Replacing a rear wiper is one of the simplest car tasks you can do. You’ll need a new blade that matches your make and model, a small flat‑head screwdriver, and maybe a wrench if the arm is secured with a bolt.

1. Lift the wiper arm away from the glass until it clicks into a locked position. 2. Locate the small clip or pin holding the blade to the arm. Press the clip and slide the old blade off. 3. Align the new blade’s hook with the arm’s slot, slide it in until you hear a click. 4. Lower the arm back onto the glass gently.

Test the new blade by turning on the wiper for a few seconds. If it clears the glass evenly, you’ve done it right. If the blade is the wrong size, it may curl or miss spots – double‑check the part number before buying.

Most rear wiper blades cost between £15 and £30, and many stores in Northwich, including Northwich Tyres Centre, stock the right fit for popular models. If you’re not comfortable with the swap, a quick visit to a local garage takes under an hour and saves you the guesswork.

Beyond replacement, keep the rear wiper in shape with a few easy habits. Spray a little washer fluid onto the glass before you use the wiper; this reduces friction and prevents the rubber from drying out. Every few months, wipe the blade with a damp cloth to clear dust and debris. If you live in a salty coastal area, rinse the rear glass and wiper after winter to avoid corrosion.

Finally, remember the rear wiper isn’t just for rain. It also clears snow, mud, and even bugs that hit the back of your car. Using the wiper on a dry, dirty surface can wear the blade faster, so give the glass a quick rinse first when it’s just dusty.By staying alert to the signs, swapping the blade yourself, and giving the system a little regular love, you’ll keep your rear view clear all year round.
