One of the most important parts of your GM vehicle would be your windshield wipers. This is because they help you to stay safe behind the wheel of your vehicle by providing maximum visibility out of the windshield. It's really important that your windshield wipers are working properly so that the frame of vision you have is clear at all times. Regardless of where you live and the climate surrounding you, you'll have to use the wipers at some point, and you want them to do a good job of clearing your windshield. You want them to work immediately when you press the button. There can be several issues that come up when cracks in the rubber develop. Exposure to the sun and elements can cause this to happen, which means that you'll need to replace them. Checking the condition of the blades on a regular basis is a smart move as a car owner. You can also pay attention to signs that they need replacement, which are always pretty obvious. Screeching sounds or squealing across the windshield are pretty clear indicators that your wiper blades are wearing out. If you find the glass is not clearing up after using the wipers, either, then you'll want to grab a new set. You can find OEM high-quality windshield wipers for your GM here at Genuine GM!
