Volkswagen Jetta Pre-Facelift Wiper (2011-2015): A Comprehensive Guide

The Volkswagen Jetta, a compact sedan renowned for its reliability and performance, has undergone several iterations throughout its production history. One of the most notable changes came with the 2011 facelift, which introduced a range of updates to the vehicle's exterior, interior, and mechanical components. However, the pre-facelift Volkswagen Jetta (2011-2015) remains a popular choice among drivers seeking a high-quality and practical sedan. This article delves into the intricacies of the wiper system employed in this particular Jetta model, providing comprehensive information on its functionality, maintenance, and potential issues.

 Wiper Assembly

The Volkswagen Jetta pre-facelift wiper assembly consists of two primary components: the wiper arms and the wiper blades. The wiper arms are attached to the vehicle's windshield and are responsible for moving the wiper blades across the glass to remove dirt, debris, and moisture. The wiper blades, which are attached to the wiper arms, are made of a flexible rubber material that conforms to the curvature of the windshield, ensuring efficient wiping action.

 Wiper Motor

The wiper motor, located beneath the windshield cowl, serves as the driving force behind the wiper assembly. It receives electrical power from the vehicle's battery and converts it into mechanical energy, which is then transmitted to the wiper arms through a linkage system. The wiper motor's speed and operation are controlled by a switch located on the steering column, allowing the driver to select the desired wiping interval and speed.

 Wiper Control Switch

The wiper control switch, typically mounted on the right-hand side of the steering column, provides the driver with a range of options for controlling the wiper system. These options include:

 Off: Disables the wiper system entirely.
 Intermittent: Activates the wipers at a predetermined time interval, with the interval adjustable by the driver.
 Low: Sets the wipers to operate at a low speed, suitable for light rain or mist.
 High: Sets the wipers to operate at a high speed, designed for heavy rain or snowfall.
 Mist: Activates a misting function, which sprays a fine mist of water onto the windshield for light cleaning or defogging.

 Wiper Fluid Reservoir

The wiper fluid reservoir, a small plastic container usually located in the engine bay, holds the wiper fluid used to clean the windshield. When the wiper switch is activated, the wiper motor triggers a pump that draws fluid from the reservoir and sprays it onto the windshield through dedicated nozzles.

 Maintenance

To ensure optimal performance and longevity of the wiper system, regular maintenance is crucial. Here are some key maintenance tips:

 Replace Wiper Blades Regularly: Wiper blades should be replaced every 6-12 months or more frequently if they show signs of wear or damage. Worn blades can result in streaking, chattering, and reduced visibility.
 Inspect Wiper Arms: Check the wiper arms periodically for any damage or corrosion. Ensure they move smoothly and are securely attached to the windshield.
 Fill Wiper Fluid Reservoir: Keep the wiper fluid reservoir filled with a high-quality wiper fluid. Regular fluid replenishment helps prevent clogging and promotes efficient cleaning.
 Clean Windshield Regularly: Maintain a clean windshield by removing dirt, debris, and insects regularly. This helps prevent wipers from skipping or chattering on the glass.

 Troubleshooting

If you experience issues with your Volkswagen Jetta pre-facelift wiper system, here are some common problems and their potential solutions:

 Wipers Not Moving: Check the wiper fuse, wiring, and switch. If all are functioning correctly, the wiper motor may need to be replaced.
 Wipers Chattering or Streaking: Replace the wiper blades. Ensure the windshield is clean and free of debris. Check for any damage to the wiper arms or linkages.
 Wiper Fluid Not Spraying: Inspect the wiper fluid reservoir for leaks or blockage. Check the nozzles for clogging and clean them as needed. Replace the fluid pump if necessary.
 Wiper System Not Working Intermittently: Faulty wiring, a malfunctioning wiper control switch, or an intermittent issue with the wiper motor could be the culprits. Seek professional diagnosis and repair.

 Conclusion

The wiper system in the Volkswagen Jetta pre-facelift (2011-2015) is a crucial component that ensures clear visibility during inclement weather. Proper maintenance and troubleshooting techniques are essential for keeping the system in optimal condition. By following the tips and information outlined in this article, you can ensure the wiper system in your Volkswagen Jetta continues to perform effectively and provide you with a safe and comfortable driving experience.
