How to Change Wiper Blades

By: HowStuffWorks.com Contributors  | 

The wiper blades on your car play a very important role, clearing rain and snow from the windshield, so that you can see clearly when driving in those adverse conditions. If your wipers have become old or worn, they will not serve their purpose at all, and might even make things worse. The sign of a worn wiper blade is its warped shape or the streaks it leaves on the windshield. Worn out wipers are of no use at all during a heavy rainfall [source: 2Carpros]. Follow these simple instructions to replace your wiper blades.

  1. Make sure the wiper blades you bought are the right size for your car. Some wiper blades fit any car model, while some are made for a specific model.
  2. Turn on the ignition and turn the wipers on. As soon as the wipers reach the center of the windshield, shut the ignition. The wipers should now be in a position to lift them up. You can skip this step if your wipers are not concealed by the hood, and simply make sure the ignition is off.
  3. Lift the wiper arm from the windshield, so that it pivots away from the windshield and is standing outward. Lift it until you feel it is in a locked position. You will know you've lifted the wiper arm enough when you feel a snap.
  4. Detach the old wiper from the wiper arm. There should be a small hook or clip that you will have to press on, in order to get the wiper to snap out of the wiper arm.
  5. Attach the new wiper blade to the wiper arm by hooking it in and snapping it in.
  6. Lower the wiper arm and place it back on the windshield [source: Repair Pal].
