Step 2: Top Off the Reservoir

Don't wait to take care of your windshield wipers. The worst time to realize they need replacing is when it's raining. Top off the reservoir and use a water repellant to improve visibility. Even with the best of care dirt, grime and the sun's UV rays will break down the soft rubber edge.

Step 3: Determine Needed Size and Connection

Check your owner's manual to determine the size and connection you need. Follow the manufacturer's instructions for replacing your particular model. Some vehicles have different sized blades on the driver and passenger sides. Others have an additional wiper on the rear windshield. Consult your owner's manual to make sure you're purchasing the correct length for your vehicle.

Step 4: Replace Blades Twice a Year

Plan on replacing your wiper blades every spring and fall. You can save a few bucks by buying inserts, but the best and safest option is to purchase whole blades. Replacing the whole blade helps avoid problems caused by improperly fitting inserts, which can increase noise, scratch your windshield or create a safety hazard.

To change blades, take the wiper assembly and pivot it away from the windshield. It should lock in place allowing you easy access to replace the blades. Paying careful attention when removing the old blades will make putting on the newer ones easier.
