How to Change Windshield Wiper Blades

Difficulty: Beginner Time: 10–15 minutes

Worn wiper blades streak, squeak, skip or leave patches you can't see through, which is a real safety problem in the rain. Replacing them takes about 10 minutes and no tools on most cars.

The trick is getting the right sizes. The driver and passenger blades are often different lengths, and some cars also have a rear wiper.

What you'll need

Step by step

1. 1

   Find the right sizes

   Look up your car at the parts store, check the wiper section of your owner's manual, or measure each blade. Driver and passenger sides are usually different lengths.

2. 2

   Lift the wiper arm

   Pull the wiper arm away from the windshield until it stays up on its own. Place a towel on the glass under it in case it falls.

3. 3

   Find how the blade attaches

   Most blades connect with a small hook at the end of the arm and a plastic clip. Look for a tab or button where the blade meets the arm.

4. 4

   Remove the old blade

   Press the tab or lift the clip, then slide the blade down toward the windshield and off the hook. It may take a firm wiggle.

5. 5

   Attach the new blade

   If the new blade came with adapters, choose the one that matches your arm. Slide it onto the hook until it clicks into place. Tug gently to make sure it is locked.

6. 6

   Lower the arm gently

   Set the arm back down onto the windshield slowly. Don't let it snap down.

7. 7

   Repeat on the other side, then test

   Replace the other blade (and the rear one if your car has it). Spray washer fluid and run the wipers to check for a clean, quiet wipe.

Tips

• Replace wiper blades about every 6–12 months. Texas heat breaks down the rubber faster.
• If new blades still streak, clean the windshield and the rubber edge with glass cleaner. Wax or road film often causes streaks.
• Many parts stores will install wiper blades for free if you buy them there.

Frequently asked questions

How do I know what size wiper blades I need?

Look up your car's year, make and model at a parts store or online, check your owner's manual, or measure each blade from end to end. The driver side is usually longer.

How often should I change wiper blades?

About every 6 to 12 months, or sooner if they streak, squeak, skip or the rubber is cracked. Sun and heat wear them out faster.

Can I change just one wiper blade?

Yes, but they usually wear at the same rate, so replacing both at once gives a more even, clear wipe.

Why do my new wipers still streak?

The windshield may have wax or road film on it. Clean the glass well and wipe the rubber edge with a damp cloth. If streaking continues, the arm may not be pressing evenly.
