| 3" | mm | 241 | 190 | 152.4 | 127 Most car, truck, and SUV owners understand the importance of having good windshield wipers on their vehicles at all times. However, many of them may not know that the windshield wiper blades and arms are moved back and forth by the Windshield Wiper Linkage. The linkage is attached to the Wiper Motor, which is typically hidden under the hood of the vehicle and protected from the elements. The Wiper Linkage may fail because it is not always protected from the sun, snow, wind, and rain and may be susceptible to wear and tear or breaking entirely without warning. The windshield wiper linkage is designed to last the life the vehicle, but like any other mechanical part it can break when you least expect it to occur. One of the most common causes of premature wear and tear is overuse in wet weather climates or in cold areas where the windshield wipers are frozen and may stick to the windshield. This causes the linkage to strip from the Wiper Arm , requiring them to be replaced. There are a few warning signs that will indicate that a problem with the windshield wiper linkage is beginning to wear out that if noticed early and fixed, can reduce additional parts breakage including the wiper motor.
