Comprehensive Guide to the Volkswagen Polo Sedan Car Wiper System (2012-2016)

 Understanding the Car Wiper System

The windshield wiper system is an essential component of any vehicle, ensuring optimal visibility during inclement weather. In the Volkswagen Polo Sedan (produced from 2012-2016), the wiper system consists of various components that work together to effectively remove rain, snow, and debris from the front windshield.

 Components of the Wiper System

 Wiper Blades

The wiper blades are the primary contact point with the windshield, responsible for wiping away moisture and dirt. They are made of natural or synthetic rubber and feature a contoured design to match the curvature of the windshield.

 Wiper Arms

The wiper arms are the metal structures that connect the wiper blades to the wiper motor. They move back and forth across the windshield, driven by the motor's rotation.

 Wiper Motor

The wiper motor is the heart of the wiper system, providing the power to drive the wiper arms. It is typically located in the engine compartment.

 Wiper Blade Replacement

Over time, wiper blades can become worn or damaged, reducing their effectiveness. It is essential to replace them regularly to maintain optimal visibility.

Materials:

 New wiper blades
 Clean cloth
 Rubbing alcohol

Steps:

1. Lift the wiper arm away from the windshield.
2. Locate the release tab on the wiper blade.
3. Gently squeeze the tab and slide the wiper blade off the arm.
4. Clean the wiper arm thoroughly with a cloth dampened with rubbing alcohol.
5. Position the new wiper blade on the arm and slide it into place until it clicks.
6. Repeat the process for the other wiper blade.

 Wiper Motor Diagnosis and Replacement

If the wiper system fails to operate correctly, it may be necessary to diagnose and replace the wiper motor.

Symptoms of a faulty wiper motor:

 Wiper arms not moving
 Wiper arms moving erratically
 Intermittent or no wiper operation

Steps:

1. Check the wiper fuse to ensure it is not blown.
2. If the fuse is intact, locate the wiper motor in the engine compartment.
3. Disconnect the electrical connector and remove the motor mounting bolts.
4. Install the new wiper motor and reconnect the electrical connector.
5. Test the wiper system to verify proper operation.

 Windshield Washers

In addition to the wipers, the Volkswagen Polo Sedan is equipped with windshield washers that spray a cleaning solution onto the windshield to remove stubborn dirt or debris.

Components:

 Washer reservoir
 Washer pump
 Nozzles
 Hoses

Operation:

1. Fill the washer reservoir with a mixture of windshield washer fluid and water.
2. Activate the windshield washers by pulling the lever on the steering column.
3. The washer pump will spray the cleaning solution through the nozzles onto the windshield.

 Troubleshooting Common Issues

 Wipers not working

 Check the wiper fuse for blown conditions.
 Inspect the wiper blades for wear or damage.
 Check the wiper arm for proper connection to the wiper motor.

 Wipers moving erratically

 Check the windshield washer fluid level.
 Inspect the wiper arms for foreign objects or debris.
 Clean the windshield with a glass cleaner to remove any contaminants.
