Having good visibility is essential for when you drive. Windshield wipers have a squeegee effect to them. Each time the thin rubber blade moves across the windshield, the droplets of water are then pulled away from your field of vision while driving. Some wiper blades may look okay, but they do a poor job of wiping the window when they are used. Other wiper blades are in worse shape and need replacing because they are cracked, split, or torn. No matter what the appearance is, if the wipers are chattering, streaking, or failing to wipe cleanly and consistently, the wiper blades should be replaced as soon as possible.


Over time, windshield wiper blades will begin to deteriorate because of environmental factors. Exposure to sunlight and atmospheric pollution can cause the rubber to age and wear down. As the windshield wiper blades age, they lose the flexibility and are less likely to wipe away cleanly. They may also develop a permanent curvature that prevents full contact with the window. The sun can harden the rubber on the wiper. When the wipers are used, they will smudge and chatter because they will not be able to follow the curvature of the window.


Heavy use on the wipers can be hard on them. Snow, ice, dust, and road grime will wear away at the edge of the blades that need to be smooth. As the edge begins to deteriorate, water will get under the blade and remain on the window. This results in poor visibility out the window. Any blade that is chattering or doing a poor job of wiping should be replaced. Also, if you notice the blade is cracked, torn, or has any other damage, you should have them replaced as soon as possible. An easy way to test your windshield wipers is to do so on a dry day. Turn on the windshield washer and if the wiper blades are not in good condition, there will be chattering or washer solvent left on the window. If there is any damage to the wiper blades, make sure to have them replaced so you are provided with the best vision possible.


Besides inspecting the windshield wipers, it is important to check the wiper fluid as well. Sometimes a nozzle may be plugged with dirt or debris. A hose may also become kinked or has come loose. The hose may also be clogged, kinked, or loose. Another thing to look at is the windshield washer reservoir. Most have a screen to filter out debris that could clog or damage the pump. If the screen has become blocked by debris, it can obstruct the flow of solvent to the washers. Make sure to bring the vehicle in if you notice any issues with it.
