Volvo 850 Sedan Car Wiper (1992-1997): A Comprehensive Guide

Introduction

The Volvo 850 Sedan, introduced in 1992, marked a significant milestone in the Swedish automaker's history. Boasting a sleek design, advanced safety features, and a powerful engine, the 850 quickly became a popular choice for discerning drivers. An integral part of the vehicle's safety arsenal was its wiper system, which played a crucial role in maintaining clear visibility during inclement weather. This article will delve into the intricacies of the Volvo 850 Sedan's car wiper system, providing a comprehensive overview of its components, operation, and maintenance.

Wiper System Components

The Volvo 850 Sedan's wiper system consists of several key components, each performing a specific function:

 Wiper Blades: The primary components that contact the windshield, removing dirt, debris, and water.
 Wiper Arms: Support and articulate the wiper blades, ensuring they move across the windshield in a consistent and effective manner.
 Wiper Motor: A small, electric motor that powers the wiper system, rotating the wiper arms and blades.
 Wiper Linkage: A series of arms and connecting points that transmit motion from the wiper motor to the wiper arms.
 Wiper Switch: Mounted on the dashboard, allows the driver to control wiper speed and mode.
 Wiper Reservoir: Stores a supply of washer fluid, which is distributed to the windshield to assist in cleaning.
 Wiper Fluid Pump: A small pump that draws washer fluid from the reservoir and sprays it onto the windshield.

Operation

When the wiper switch is activated, an electrical signal is sent to the wiper motor. The motor responds by rotating the wiper linkage, which in turn causes the wiper arms to move across the windshield. The speed of the wiper system can be adjusted by the driver using the wiper switch.

In addition to manual operation, the 850 Sedan's wiper system also features an automatic mode. When the automatic mode is engaged, the wiper system is triggered by the rain-sensing technology. This system uses an optical sensor mounted on the windshield to detect the presence of water droplets. When rain is detected, the wiper system is automatically activated, adjusting its speed based on the intensity of the rainfall.

Maintenance

To ensure optimal performance, the Volvo 850 Sedan's wiper system requires regular maintenance:

 Wiper Blade Replacement: The wiper blades should be replaced every 6-12 months, depending on the level of use and exposure to the elements. Worn wiper blades can leave streaks and compromise visibility.
 Wiper Arm Inspection: Periodically inspect the wiper arms for any damage or loose connections. Faulty wiper arms can affect the proper operation of the system.
 Wiper Motor Lubrication: The wiper motor should be lubricated every year or two to prevent wear and ensure smooth operation.
 Wiper Fluid Replenishment: Ensure that the wiper fluid reservoir is always filled with a high-quality solution. The use of washer fluid can enhance the cleaning effectiveness of the wiper system.
 Wiper Linkage Maintenance: Lubricate the wiper linkage regularly to ensure smooth movement and prevent premature wear.

Troubleshooting

If the Volvo 850 Sedan's wiper system is not functioning properly, the following troubleshooting steps can be helpful:

 Check Electrical Connections: Ensure that all electrical connections to the wiper system are secure. A loose connection can cause the system to malfunction.
 Inspect Wiper Motor: Listen for any unusual noises or check for burning smells coming from the wiper motor. A faulty wiper motor may require replacement.
 Test Wiper Switch: Verify that the wiper switch is functioning correctly by operating the wipers in different modes. A faulty switch may need to be replaced.
 Inspect Wiper Linkage: Examine the wiper linkage for any broken or damaged components. Worn or damaged linkage can affect the movement of the wiper arms.

Conclusion

The Volvo 850 Sedan's car wiper system is an integral safety feature that plays a vital role in maintaining clear visibility during inclement weather. Understanding its components, operation, and maintenance requirements is essential for maximizing its effectiveness and ensuring a comfortable and safe driving experience. By following the tips outlined in this article, owners of the Volvo 850 Sedan can keep its wiper system in optimal condition for years to come.
