This section will help you replace your wiper blades quickly and correctly. Although replacing wiper blades isn't usually difficult, be sure to READ all instructions provided. Before You Begin Purchase new wiper blades that are the right size and attachment style for your specific automobile. The most popular sizes of blades for vehicles today range between 16 and 21 inches in length. Some vans and cars may require a larger size.
Many newer vehicles require a different length on one side than the other.
If you are not sure of the size, measure your old blades before purchasing new ones. It is usually far easier to replace the blade assembly rather than the rubber insert alone, so that's what we'll cover here. Gather together all the tools and equipment you'll need before you start. Some wiper system designs allow you to lift the wiper arms off the windshield, and extend them toward the front of the vehicle. The arms will stay in this position, which allows for the easiest blade replacement possible.
