If the wiper blade isn’t resting against the glass with enough tension or has become bent, you’ll need to replace the entire blade.

Remember that the left and right wiper blades may be different lengths.

Some wipers will only come two to three inches away from the windshield; if that’s the case, don’t try to force the wipers up any further. On some cars it may be easier to turn on the wipers and when they start to move turn off the ignition. This will allow you to move the arm up to have better access to remove the wiper blade.

You may need to tap or tug on the blade a bit to remove it if there’s built up debris or corrosion. Sometimes it helps to push the wiper up into the holder, press the tab, and then remove. The bare metal arms are now exposed, and, if left in the standing position, they can snap back and damage your windshield. So, to be safe, gently place the metal arms back against the windshield until you’re ready to put on the new ones. To be extra safe, place a rag or cloth underneath the metal arm while it rests on the windshield.

The metal hook should push up against the rubber insert.

Repeat with the other wiper blade.

If the new wipers are streaky, first try cleaning the rubber insert with alcohol wipes or a cloth soaked in mineral spirits. If the wipers are still streaky, check that the blades are properly installed. Verify that you’ve installed each blade on the correct side and check that the wiper is properly oriented. If all else fails, stop by your local auto-parts store for help.

Push in the tabs and pull up on the blade to slip it off the assembly. If you find pushing the tabs in to be difficult, you can use a pair of needle-nose pliers to help you. On some models, the wiper arm must be removed so that the rubber insert can be replaced correctly.

When the insert is in place, be sure the clamps on the blade are securely holding it in place. Verify that the far pad is secured in place by the last clamp.
