Replacing Windshield Wipers

I laugh when I visit my local auto parts store and see that they’re
having a sale on wiper blades, offering free installation. The free
installation only applies if I buy the most expensive blades in the
store, so I started changing them on my own. You’ll need new wiper
blades after about six months or a year of use. You probably tend to go a
little longer before asking your mechanic to change them, but you
shouldn’t deal with the danger of streaking while you put off an
inconvenient trip to the auto shop.

Wiper blade setup differs
quite a bit from car to car, so you may have to follow a few different
steps according to your owner’s manual. Basically, the process is
similar to changing your air filter:

  1. Lift the blades, as if you were washing your windshield by hand, and remove the old blades.
  2. Pay attention to how the old blades connect to the metal arms.
  3. On most models, you’ll see a tab on the underside of the wiper. Push the tab to remove the old blade.
  4. Attach
    the new blades, being careful not to bend the wiper arms or scratch
    your windshield. Line everything up and make sure the new ones are
    secure and tight.

If you get distracted or just can’t
remember exactly how the new blades should fit on the wiper arm, don’t
worry. The packaging for the new blades should have a general set of
instructions and a helpful diagram.
