How to Replace Windshield Wiper Blades (J-Hook)

Wipers streaking, skipping, or squeaking across the glass? New blades take about five minutes to put on, and you don't need any tools. Here's how to change the most common kind, the J hook.

1. Step 1: Get The Right Size

First, get the right size. The driver's side and passenger side are often different lengths. The store's fit guide, or the blade package, will list them by your car's year, make, and model. Replace them as a pair, since they wear out together.

2. Step 2: Lift The Arm, Protect The Glass

Lift the wiper arm up, away from the windshield. Lay a folded towel on the glass under it. The arm is spring loaded, and if it snaps back down without a blade, it can crack your windshield.

3. Step 3: Remove The Old Blade

Find the small tab where the blade meets the arm. Press it, then slide the blade down, toward the glass, so it unhooks from the bend in the arm. Pull it free.

4. Step 4: Click In The New One

Some new blades have an adapter that you rotate open first. Slide the hook of the arm into the new blade's adapter, and pull it up until you hear a click. Give it a gentle tug to make sure it's locked.

5. Step 5: Lower It Gently

Lower the arm gently back onto the glass, and remove the towel. Then do the other side, and test them with a little washer fluid.

6. How Often?

Plan on new blades about once or twice a year, or any time they start to streak, skip, or chatter. Some cars, especially European models, use a pin style arm instead of a J hook, so check the package or your owner's manual.
