When the rain starts coming down, a squeaky or streaky wiper can feel like a nightmare. The good news? Swapping out old blades is one of the easiest DIY jobs on a car. In this guide you’ll discover how to choose the best replacement, fit it without a hitch, and keep it lasting longer.
First, check your vehicle’s owner manual or look at the part number on the existing blade. Most manufacturers use a size code like 22"‑16"‑24" that tells you the length for the driver’s side, passenger’s side, and rear (if you have one). If you’re unsure, measure the blade from end to end.
Next, decide on the style. Conventional blades have a simple rubber strip, while beam blades use a curved, all‑rubber design that clings better to curved windshields. Beam blades are quieter and work well on modern cars, but they can be pricier. For older models with a metal frame, stick with the classic style.
1. Lift the wiper arm away from the glass until it locks in a position that lets you work safely. 2. Locate the small tab or clip that holds the blade to the arm. Press it, slide the old blade off, and set it aside.
3. Take the new blade, line up the mounting hook with the arm’s slot, and slide it until you hear a click. Give it a gentle tug to make sure it’s secure. 4. Lower the arm back onto the windshield, being careful not to snap the blade.
Repeat the process on the other side. If your car has a rear wiper, the steps are the same but the arm is usually smaller and may use a different clip type.
After both sides are fitted, run the wipers on a wet windshield. Watch for streaks or missed spots. If the blade doesn’t sit flat, double‑check the clip alignment.
Now that you’ve installed fresh blades, follow these quick care tips to stretch their life. Keep the rubber clean by wiping it with a damp cloth after each wash—salt and road grit can tear it down fast. When storing the car for winter, lift the arms slightly to relieve pressure on the blades.
If you notice a squeak after a few weeks, try a light spray of silicone‑based spray on the rubber. This reduces friction without attracting dirt. And remember, replace blades every 6‑12 months, or sooner if you see cracking, splitting, or a reduced wiper sweep.
That’s it—no special tools, no trips to the garage, and you’ll get clear visibility when the weather turns nasty. Keep this guide handy, and next time the rain hits, you’ll know exactly what to do.
