If you need to replace your windshield wipers, you might want some guidance as to how to do it. First, you will need to check them. They usually fail because of deformations on the surfaces of the blades.
They are sold based on the length of the blade. You should pay attention to both the lengths – the length of the blades on the driver and passenger sides of the car may not be the same. How you will remove the wiper blade from the car will depend on the kind of wiper blade you are working with.
In order to install a new wiper blade, you should pay attention to the type of wiper arm and wiper blade as well. There will be different instructions depending on the type. If you have doubts, you might want to consult with a local car parts store, as they will be able to give you useful guidance. If you attempt to do it on your own without having any real knowledge of wiper blades, you might end up causing damage to the wiper blade and ultimately costing yourself more money than you would have if you had just sought help in the first place.
