Your windshield wiper system consists of wiper blades and wiper arms connected to motors, gears, and various arms and linkages located beneath the hood of your car. Many people do not give a second thought to their GMC wiper arms, as the wiper blades are usually the first component considered. However, when your wipers are not functioning properly to give you a clear view of the road, you should inspect your GMC wiper arms along with your wiper blades. The GMC wiper arms work in conjunction with the wiper blades to clear rain, snow, salt, mud, insects and other detritus from your windshield. If you cannot see in front of your vehicle, you pose a danger to yourself and others on the road. GMC wiper arms connect your wiper blades to the motor, allowing the blades to move freely and efficiently over your glass windshield. If your GMC wiper arms are worn or cracked, the wiper blades will not be properly aligned. This can cause smudging or "missed" spots on the windshield. If you have already changed your wiper blades and you still are not getting a clear windshield, you should install new GMC wiper arms as well. The wiper blades should rest snug and firm against the glass, and should be able to travel on a complete path across the width of your windshield. Purchasing new GMC wiper arms can mean the difference between a blurry windshield and a crystal-clear view of the road. Believe it or not, GMC wiper arms come in many different styles and colors, so you can customize the look of your windshield wipers.
