Genuine GM windshield wipers are the best way to maintain good visibility through your windshield in bad weather. Their motor-driven metal arms pivot to wick away rain and debris dependably from your front and sometimes rear windows. That's not to mention that they help remove ice and snow with assistance from windshield washer fluid. Windshield wiper blades, however, are the parts of a wiper system that do that job. They're the long rubber surfaces connected at one end to the wiper arms. As the arms move in sync, the blades travel across your windshield; the blades themselves are what push water and dirt away from the glass surface. You can often adjust blade movement by adjusting wiper speed, and most wipers today run continuously, intermittently, or both. If you notice their rubber cracking or breaking, however, it's probably time to replace your wiper blades. The same goes for if your wipers leave streaks, the blades squeak, or they aren't making the necessary contact for cleaning. Of course, if your blade frames are bent, damaged, or just plain broken, or their adhesive's losing stickiness, these are definite indicators you should change wiper blades. If you've got a project planned, the best option for your GM vehicle is OEM; wiper blades made by yours are designed compatible with your model.
