Understanding the Importance of Rear Windshield Wiper Size
The size of your rear windshield wiper is a critical aspect of maintaining visibility while driving, especially during rainy or snowy conditions. A rear windshield wiper that is too small may not effectively clear water or debris, compromising your ability to see behind your vehicle. On the other hand, a rear windshield wiper that is too large may cause excessive wind noise, water spray, or even damage to the wiper arm or rear window.
In this section, we will delve into the world of rear windshield wiper sizes, exploring the factors that influence their design, the benefits and challenges of different sizes, and practical tips for selecting the right wiper for your vehicle.
Measuring the Rear Windshield Wiper Arm
To determine the correct size of your rear windshield wiper, you’ll need to measure the wiper arm. This is typically done by measuring the distance between the mounting points on the rear window and the length of the wiper arm itself. You can find the specifications for your vehicle’s rear windshield wiper in your owner’s manual or by consulting with a dealership or auto parts store.
Here’s a general guide to help you measure the rear windshield wiper arm:
- Measure the distance between the mounting points on the rear window (A). This is usually indicated by a series of holes or tabs.

If you’re not comfortable with this process, it’s recommended to consult a professional mechanic or the vehicle’s manufacturer for assistance.
What if my rear windshield wiper is not working properly?
If your rear windshield wiper is not working properly, there are several potential causes. First, check the electrical connector and ensure it’s securely connected. Next, inspect the wiper arm and blade for any signs of wear or damage. If the wiper is not turning, check the motor for any issues or blockages. If the wiper is not clearing the windshield effectively, adjust the wiper arm to the correct position or replace the wiper blade. If none of these solutions work, it’s recommended to consult a professional mechanic for further assistance.
Which is better, a frame-style or beam-style rear windshield wiper?
The choice between a frame-style and beam-style rear windshield wiper ultimately depends on your vehicle’s specific needs and preferences. Frame-style wipers are more common and typically offer a wider arc length, making them suitable for larger rear windshields.
