Keeping your rear windshield clear is essential for safe driving, especially during inclement weather. The back windshield wiper on your Toyota Corolla plays a crucial role in maintaining visibility. This guide will explain how to use the back windshield wipers effectively, including operation, maintenance, and troubleshooting.
Understanding the Back Windshield Wiper System
What is the Back Windshield Wiper?
The back windshield wiper is designed to remove water, snow, and debris from the rear glass of your Toyota Corolla. It helps improve visibility, particularly in rainy or snowy conditions, making it an essential feature for safe driving.
Components of the System
- Wiper Arm: The metal arm that holds the wiper blade and swings back and forth across the glass.
- Wiper Blade: The rubber part that makes contact with the glass, clearing water and debris.
- Wiper Motor: The electric motor that powers the wiper arm’s movement.
- Control Switch: The lever or knob inside the vehicle that controls the wiper’s operation.
How to Operate the Back Windshield Wiper
Step 1: Locate the Control Switch
In most Toyota Corolla models, the back windshield wiper control is found on the stalk that also controls the front windshield wipers. Here’s how to identify it:
- Driver’s Side Stalk: Look for the wiper control lever on the right side of the steering column.
- Wiper Symbols: The symbols on the stalk indicate different wiper functions, including the rear wiper.
Step 2: Activating the Wiper
- Turning On the Wiper: To activate the back windshield wiper, push the control switch away from you. This usually engages the wiper in the “on” position.
- Adjusting Speed: Some models may allow you to adjust the speed. If your Corolla has multiple settings, you can find them by rotating or pushing the control switch further.
Step 3: Engaging the Washer Fluid
- Using the Washer Fluid: To spray washer fluid onto the back windshield, pull the wiper control towards you. This action activates the washer pump, spraying fluid onto the glass while the wiper moves.
- Clearing Debris: This function is useful for removing stubborn dirt or grime. Allow the wiper to run for a few moments after using the washer fluid for optimal cleaning.
Maintenance Tips for Back Windshield Wipers
Regular Inspections
- Check the Wiper Blade: Inspect the rubber wiper blade regularly for signs of wear, such as cracks or fraying. A worn blade can lead to streaking and reduced visibility.
- Clean the Wiper Arm and Blade: Periodically clean the wiper arm and blade with a damp cloth to remove dirt and debris. This helps maintain effective wiping action.
Replacing Wiper Blades
- When to Replace: Wiper blades should be replaced every 6-12 months, depending on usage and environmental conditions.
- How to Replace: To replace the back windshield wiper blade:
- Lift the wiper arm away from the glass.
- Press the tab on the wiper blade and slide it off the arm.
- Align the new blade with the arm and slide it into place until it clicks.
Troubleshooting Common Issues
Wiper Not Moving
If the back windshield wiper is not moving, consider the following steps:
- Check the Fuse: A blown fuse can prevent the wiper motor from operating. Refer to your owner’s manual to locate the fuse box and check for any blown fuses related to the wiper system.
- Inspect the Wiper Motor: If the fuse is intact, the motor itself may be faulty. Consult a professional mechanic for diagnosis and repair.
Streaking or Poor Performance
If the back wiper leaves streaks or fails to clean effectively, try these solutions:
- Clean the Wiper Blade: Dirt buildup on the blade can lead to poor performance. Clean it thoroughly.
- Replace the Blade: If cleaning doesn’t resolve the issue, consider replacing the wiper blade.
Washer Fluid Not Spraying
If the washer fluid does not spray onto the back windshield, check the following:
- Fluid Level: Ensure that the washer fluid reservoir is filled.
- Clogs: Inspect the washer fluid lines for any clogs. If you suspect a blockage, consult a mechanic for assistance.
Conclusion
Using the back windshield wipers on your Toyota Corolla is essential for maintaining visibility in adverse weather conditions. By understanding how to operate the wiper system, perform regular maintenance, and troubleshoot common issues, you can ensure that your rear windshield remains clear and safe for driving. Remember to check your wipers regularly and replace them when needed, allowing you to enjoy a safer driving experience.
