Windscreen Wiper Repair: Easy DIY Fixes & When to Get Help

If your wipers are streaking, squeaking, or just won’t move, you don’t have to panic. Most issues are quick to diagnose and cheap to fix. Below you’ll find the usual suspects, simple checks, and step‑by‑step guides that anyone can follow.

Common Wiper Issues and Quick Checks

First thing’s first – listen to the wiper motor. If it hums but the arms don’t move, the linkage is probably stuck. If you hear a click and nothing happens, the motor may be dead or the fuse blown. Grab the owner’s manual and locate the fuse box; a quick visual check can save you a costly part.

Next, look at the rubber blades. Over time they harden, split, or collect debris. A simple wipe with soapy water often restores grip. If the blade still leaves streaks, it’s time for a new set. Most cars use a 16‑inch blade on the driver side and a 14‑inch on the passenger side, but check the label on the old blade to be sure.

Another easy culprit is the wiper arm tension. Loose arms can cause uneven pressure, leading to streaks. Lift the arm off the windshield, move it to the neutral position (usually a vertical line), and tighten the nut at the base. Give it a gentle tug – it should feel snug but not rigid.Don’t forget the wiper linkage. It’s a small metal rod that connects the motor to the arms. Dirt or rust can jam it. Spray a bit of penetrating oil where the linkage meets the motor, then move the wipers a few times to work it in. If the motion feels rough, you may need to replace the linkage.

Step‑by‑Step Repair Guides

1. Replacing a Blade
a) Pull the old blade off the arm by pressing the release tab.
b) Slide the new blade onto the hook until you hear a click.
c) Test the wiper – if it wipes clean, you’re done.

2. Fixing a Stuck Motor
a) Disconnect the battery to avoid any electrical surprise.
b) Remove the plastic cover over the motor (usually a few clips).
c) Check the wiring for corroded terminals; clean with a wire brush.
d) If the motor spins freely by hand, the issue is electrical – replace the fuse or motor relay.
e) Reassemble and reconnect the battery.

3. Replacing the Wiper Motor
a) Raise the hood and locate the motor at the base of the windshield.
b) Unplug the connector and remove the mounting bolts (typically two).

c) Take out the old motor and slide the new one into place.
d) Bolt it back, plug the connector, and test the movement.

Most DIYers can finish these jobs in under an hour with basic tools – a screwdriver set, a socket wrench, and a pair of pliers. If you run into rusted bolts or a cracked motor housing, it’s smarter to call a professional rather than force anything.

Remember, keeping your wipers in good shape isn’t just about visibility; it’s a safety issue. A well‑functioning wiper system clears rain, snow, and dust, helping you stay in control on wet roads. Schedule a quick visual check every six months, especially before winter.

Got a stubborn problem that these steps didn’t solve? Write down the exact symptoms, take a photo of the wiper assembly, and bring it to a trusted garage. Most mechanics can pinpoint the issue faster when they have clear details.

Bottom line: most wiper troubles are cheap, quick fixes. With a little patience you can keep your windshield clear without breaking the bank.
