What is the Correct Size for My Rear Windshield Wiper?
Finding the correct size for your rear windshield wiper is crucial for maintaining clear visibility and ensuring safe driving conditions. To determine the right size, you should consult your vehicle’s owner’s manual or measure the existing wiper blade. Typically, rear wiper sizes range from 11 to 16 inches, but this can vary based on the make and model of your vehicle.
How to Determine the Right Rear Windshield Wiper Size
Check Your Vehicle’s Manual
The easiest way to find the correct size for your rear windshield wiper is to consult your vehicle’s owner’s manual. This document provides specific details about your car, including the recommended wiper blade sizes for both the front and rear windows.
Measure the Existing Wiper Blade
If you don’t have access to the manual, you can measure the existing wiper blade. Use a tape measure to determine the length from one end of the blade to the other. Make sure to measure in inches for accuracy, as most wiper blades are sized in this unit.
Use Online Resources
Many automotive websites and online retailers offer tools to help you find the correct wiper blade size. By entering your vehicle’s make, model, and year, you can quickly identify the recommended blade size for your rear windshield.
Why the Correct Wiper Size Matters
Ensures Proper Coverage
Using the correct wiper size ensures that your rear windshield is properly covered, providing optimal visibility. A blade that’s too short may leave parts of the glass uncleared, while a blade that’s too long might not fit properly or could damage the wiper mechanism.
Prevents Damage
Installing the wrong size wiper blade can lead to damage. An oversized blade might cause strain on the wiper motor or could scratch the glass, while an undersized blade might not function effectively, leading to reduced visibility.
Enhances Safety
Clear visibility is essential for safe driving, especially in adverse weather conditions. The right rear wiper blade helps maintain a clear view, reducing the risk of accidents due to poor visibility.
