1. Adjust the Wiper Arm:
- Locate the rear wiper arm and check if it's properly aligned.
- If it's not, gently bend the wiper arm to adjust the angle at which the wiper sits on the window.
2. Inspect the Wiper Blade:
- Check the condition of the rear wiper blade. If it's worn or damaged, it won't be able to make proper contact with the window.
- Replace the wiper blade if necessary.
3. Clean the Windshield:
- Make sure the rear windshield is clean and free from dirt, debris, or any contaminants.
- Clean the windshield using a glass cleaner and a microfiber cloth.
4. Check Wiper Arm Tension:
- Ensure that the wiper arm has the proper tension to hold the blade securely against the window.
- Adjust the tension if needed by tightening or loosening the nut or bolt that secures the wiper arm to the vehicle.
5. Check Wiper Blade Length:
- Verify that the length of the wiper blade matches the curvature of the rear windshield.
- If the wiper blade is too short or too long, it won't be able to contact the entire surface of the window properly.
6. Test the Wiper:
- Turn on the rear wiper and check if it moves smoothly across the entire windshield.
- If it doesn't, make necessary adjustments or repeat the above steps.
It's important to ensure that the rear wiper makes full contact with the window to maintain good rear visibility and safe driving conditions.
