One often overlooked wear item on your car is the wiper blades. This is one of those things that can easily ruin your day if the weather suddenly turns bad. Replacement of the blades is very easy and should take no longer than 15 minutes.

If you live in a wetter climate, then you'll understand the importance of wiper blades that work well. If running the wipers just streaks the windshield, it's time for new blades.

Lower quality blades tend to dry out or crack quicker than quality ones. They are more expensive, but they last longer and do a nicer job of keeping the water off the windshield.

While changing the wiper blades on your own car is simple, quick and easy make that you do not let the wiper arm swing back and hit the windshield with no blade on the end.

While changing the wiper blades on your own car is simple, quick and easy make that you do not let the wiper arm swing back and hit the windshield with no blade on the end. If this happens you can easily crack the glass and instead of saving yourself money it will end up costing you a lot. If you are worried about it place a large folded towel over the windshield before you begin.

Lift the arm up off the windshield and squeeze the two tabs on each side of the arm inwards (red arrows).

Lift the arm up off the windshield and squeeze the two tabs on each side of the arm inwards (red arrows). Both blades are replaced the same way.

With the tabs pushed in (red arrows) pivot the blade off the end of the arm (yellow arrow).

You can see how the blade cartridge or mount opening (red arrow) sits in the arm opening (yellow arrow) and then pivots back down to lock in place.

The same thing goes for protecting the rear glass even though the risk is not as great due to the angle of the arm.

Swing the arm away from the glass and then pivot the blade 90 degrees from the arm.
