Operating the Rear Windshield Wiper
To effectively use the rear windshield wiper, it is essential to understand the specific controls and settings available in your vehicle. Most cars are equipped with a dedicated control stalk or switch, usually located on or near the steering column, or on the dashboard. The controls allow you to activate the rear wiper independently or in conjunction with the front wipers.
The typical operation includes the following functions:
- Intermittent wipe: The rear wiper activates at set intervals, clearing light moisture or mist without continuous operation.
- Continuous wipe: The rear wiper operates continuously, which is useful in heavy rain or snow.
- Rear washer spray: Activates the washer fluid spray on the rear windshield, often combined with a few wipes to clean dirt or debris.
To operate the rear wiper, perform these steps:
- Locate the rear wiper control, commonly a rotating switch or a push-button.
- Turn or press the control to the desired setting (intermittent or continuous).
- To use the washer fluid, pull or push the control lever as specified in your vehicle’s manual.
Always ensure the rear windshield is clear before engaging the wiper to prevent damage to the blade or motor.
Maintenance Tips for Rear Windshield Wipers
Proper maintenance of the rear windshield wiper ensures optimal performance and longevity. Neglecting this component can lead to poor visibility and potential safety risks. Key maintenance tips include:
- Regular inspection: Check the wiper blade for cracks, splits, or stiffness at least once a month.
- Cleaning: Wipe the blade and rear windshield regularly with a damp cloth to remove dirt and debris.
- Replacement: Replace the rear wiper blade every 6 to 12 months, or sooner if performance declines.
- Check washer fluid: Keep the washer fluid reservoir filled with a suitable cleaning solution.
Avoid using the wiper on a dry windshield as this can cause premature blade wear. Additionally, during winter, clear any ice or snow buildup manually before activating the wiper.
Troubleshooting Common Rear Windshield Wiper Issues
If the rear windshield wiper is not functioning correctly, it may be due to various issues ranging from electrical problems to mechanical faults. Here are some common problems and how to address them:
| Issue | Possible Cause | Recommended Action |

By adhering to these safety practices, you maintain clear rear visibility, contributing to overall road safety.
Operating the Rear Windshield Wiper
The rear windshield wiper is a vital feature for maintaining rear visibility during adverse weather conditions, such as rain, snow, or dust. Understanding its operation enhances safety and driving comfort.
Most vehicles equipped with a rear windshield wiper have a dedicated control stalk or switch, typically located on or near the steering column or dashboard. The operation can vary slightly depending on the make and model, but the general principles remain consistent.
- Locate the Control: Identify the rear wiper control, often marked with an icon resembling a rectangle with a wiper blade.
- Control Positions: The control may have several positions:
| Position | Function | Typical Usage |
|---|---|---|
| Off | Rear wiper is inactive | Normal, dry conditions |
| Intermittent (INT) | Wiper activates at timed intervals | Light rain or drizzle |
| On (Continuous) | Wiper operates continuously | Heavy rain or snow |
| Wash (Spray) | Activates washer fluid spray and wiper | Cleaning rear windshield |
To operate the rear wiper, move the control to the desired setting based on weather conditions. For example, if light rain is present, set the wiper to intermittent. For persistent precipitation, switch to continuous operation. When the rear glass is dirty or obstructed, activating the wash function sprays washer fluid and cleans the surface with the wiper blade.
Best Practices for Using the Rear Windshield Wiper
Using the rear windshield wiper correctly not only improves visibility but also prolongs the life of the wiper system.
- Use as Needed: Engage the rear wiper only when visibility is impaired to avoid unnecessary wear.
- Operate Washer Fluid Properly: Use washer fluid rather than water to prevent freezing and improve cleaning efficiency.
- Monitor Wiper Blade Condition: Regularly inspect the rear wiper blade for cracks, stiffness, or damage. Replace blades every 6-12 months or sooner if performance declines.
- Deactivate When Not in Use: Always turn off the rear wiper after use to prevent motor strain and battery drain.
- Avoid Using on Dry Glass: Do not operate the wiper on a dry windshield, as this can cause scratching and reduce blade lifespan.
- Clear Heavy Snow and Ice Manually: Remove heavy accumulations before using the rear wiper to avoid damaging the motor or blades.
Troubleshooting Common Rear Windshield Wiper Issues
Understanding common issues and their solutions ensures continuous, reliable operation of the rear wiper system.
| Issue | Possible Cause | Recommended Solution |
|---|---|---|
| Wiper does not operate | Blown fuse, faulty motor, or disconnected wiring | Check and replace fuse; inspect wiring; consult mechanic for motor repair |
| Wiper operates intermittently or erratically | Faulty switch, poor electrical contact, or motor wear | Clean switch contacts; test and replace switch or motor if needed |
| Wiper blade leaves streaks or smears | Worn or damaged blade | Replace wiper blade with manufacturer-recommended type |
| Washer fluid does not spray | Empty washer reservoir, clogged nozzle, or pump failure | Refill reservoir; clean nozzles; test washer pump operation |
Regular maintenance and prompt attention to issues will ensure the rear windshield wiper remains functional and effective, providing clear rear visibility under various driving conditions.
