What Causes Windshield Wipers Not to Return to Position?
2 Answers
Windshield wipers not returning to position may be due to poor contact in the wiper motor or battery circuit, or poor contact in the motor's wiring. Additional information: 1. Introduction: The windshield wiper is an important accessory installed on the windshield, designed to remove rain, snow, and dust that obstruct the view. Thus, it plays a crucial role in driving safety. 2. Principle: The electric motor in the windshield wiper drives the output shaft through a worm gear on the armature shaft and drives the output gear via an idler and idler shaft. The output arm connected to the wiper linkage is then operated by the output shaft. When the motor rotates, the output arm and linkage are driven to move back and forth.
Last time I was driving, the windshield wipers suddenly stopped returning to their original position and got stuck in the middle, which was quite annoying. At first, I thought it was just stuck due to heavy rain, but later I realized it might be a mechanical issue, such as a loose connection on the wiper arm or a jammed linkage. It could also be an electrical problem, like a faulty motor or a burned-out relay. In cold weather, ice and snow buildup on the wiper joints make them more prone to getting stuck. I recommend parking in a garage or regularly cleaning the wiper blades to prevent ice accumulation. If this happens, don’t force them to move—try simple de-icing or inspection first. If that doesn’t work, take the car to a repair shop promptly, as poor visibility during rain increases the risk of accidents. Remember, regular maintenance can save a lot of hassle.
