STEP 1: Purchase the correct replacement windshield-wiper blades for your car at an auto-parts store. Buy the entire blade, not just the rubber blade insert.
STEP 2: Open the package and find the attachment that matches the one on the wiper blade on your car. Read through the directions to see how to connect the attachment to the blade.
STEP 3: Pull the wiper arm up so it is no longer resting on the windshield.
STEP 4: Remove the old wiper blade from the wiper arm (see A). This typically involves pushing on a tab and pulling the wiper blade off or lifting a tab with a small screwdriver.
STEP 5: Insert the attachment onto the new blade or onto the wiper arm (see B). On some cars, it may be easier to put the attachment on the wiper blade first; on other models, it is easier to first put the attachment onto the wiper arm. Listen for a click.
STEP 6: Tug on the wiper blade to make sure it is securely attached and won't fly off later.
STEP 7: Gently lower the wiper arm onto the windshield.
Overall Tips & Warnings
In preparation for winter, replace your windshield-wiper blades every fall.
If you have trouble accessing the wiper blades, turn on the wipers, then switch off the ignition when the blades are vertical on the windshield.
