Wipers are an essential component of any vehicle, serving to keep the windshield clear from rain, snow, and debris. While it’s common for motorists to focus on the functionality of the front and back wipers to ensure their visual clarity while driving, it’s not unusual for car owners to face the frustrating issue of front wipers not working while the rear wiper continues to perform its role. This article delves into the reasons behind this common automotive issue, explores potential problems, and provides effective solutions for when your front wipers stop working.
Understanding the Windshield Wiper System
To address wiper issues, it’s essential to understand the basic components of the windshield wiper system. The windshield wiper system is composed of several key parts:
- Wiper Blades: The rubber components that make contact with your windshield.
- Wiper Arms: The mechanisms that connect the wiper blades to the wiper motor, enabling them to move back and forth.
- Wiper Motor: The electrical component that powers the movement of the wiper arms.
- Wiper Linkage: The system of rods and pivots that transfers motion from the motor to the wiper arms.
- Switches and Relays: The controls that allow the driver to operate the wipers and adjust their settings.
When you activate the front wipers, the voltage from the battery is sent to the wiper motor via a series of switches and relays. This initiates the movement of the wiper arms, allowing them to clear the windshield. If your front wipers fail to respond but the rear wiper functions correctly, it can indicate a problem specifically with the front wiper system.
Common Causes of Front Wipers Not Working
Several factors could contribute to the malfunction of your front windshield wipers while the rear ones remain operational. Understanding these causes will aid in troubleshooting and resolving the issue. Here are some of the most common reasons:
