Understanding Windshield Wiper Mechanisms
Windshield wipers are an essential component of any vehicle, providing clear visibility during rainy, snowy, or dusty conditions. However, when they fail to work, it can be frustrating and even hazardous. To troubleshoot the issue, it’s essential to understand how windshield wipers work and the potential causes of their malfunction.
Types of Windshield Wiper Mechanisms
There are two primary types of windshield wiper mechanisms: intermittent and constant speed. Intermittent wipers switch between on and off states to improve visibility, while constant speed wipers operate continuously at a set speed. Understanding the type of mechanism in your vehicle can help you identify potential issues.
Intermittent wipers, for example, use a cam and arm system to switch between on and off states. The cam is connected to the wiper arm, which moves back and forth to create the on-off pattern. Constant speed wipers, on the other hand, use a motor and gearbox system to operate continuously at a set speed.
Common Causes of Windshield Wiper Malfunction
When windshield wipers fail to work, it’s often due to a mechanical or electrical issue. Here are some common causes:
-
Wiper arm or blade damage: Inspect the wiper arm and blade for signs of wear, cracks, or breaks. If damaged, replace the wiper arm or blade.
