Understanding Your Windshield Wiper System
Before diving into the issues that can cause your passenger side wiper to fail, it’s important to understand how windshield wipers operate. Most vehicles come equipped with two wipers: one for the driver’s side and one for the passenger’s side. These wipers are usually powered by a single motor that drives both arms through a linkage system.
Components of the Windshield Wiper System
To appreciate why your passenger side wiper may not be working, let’s take a look at the key components involved in the system:
- Wiper Motor: This electric motor powers the wipers, controlling their movement and speed.
- Linkage Assembly: This mechanical link connects the motor to the wiper arms, transferring the motion.
- Wiper Arms: The arms are pivotal; they hold the wiper blades and allow them to sweep across the windshield.
- Wiper Blades: These are the rubber components that make contact with the glass, removing water and debris.
- Switch and Relay: These components enable you to control the wipers from inside your vehicle.
Understanding these components helps you pinpoint where the issue might be occurring.
Why is the Passenger Side Wiper Not Working?
There are several reasons why the passenger side windshield wiper may fail while the driver’s side continues to operate without a hitch. Let’s explore the most common culprits.
