Troubleshooting and Fixing Your Rear Windshield Wiper Arm

Having a properly functioning rear windshield wiper arm is essential for maintaining clear visibility while driving during bad weather. However, issues with the wiper arm can be frustrating. This guide will help you identify problems and solutions for your wiper arm, ensuring you can see clearly and drive safely.

Identifying the Problem with Your Rear Windshield Wiper Arm

First, you need to identify what may be wrong with your wiper arm. If the arm is entirely missing, replacement is the only option. If you suspect the arm is missing and have not found it, check common areas where it might be hidden or damaged.

Another issue you might encounter is when the wiper arm does not move at all. If you can hear it moving but see no visible wiping action, there are a few possible components that could be the culprit:

Electrical Issues

Do you hear any movement but no flapping or wiping action? This issue might be caused by one of the following:

Bad wiring: Check the connections and wiring to see if they are loose or damaged, Bad fuse: If the wiper arm is not receiving power, check the fuses for signs of damage or breakage, Short circuit: It's possible there is a short circuit that should be diagnosed by a professional, Motor problem: If the motor is not at fault, the issue might lie with the wiper arm itself or the electrical connection to it.

Diagnostic Steps

To determine if the problem is with the motor or the electrical component, you can use a voltage tester. Connect the voltage tester to the wiper arm motor and check if it is receiving power. If the motor is not getting power, replace the fuse. If the motor still does not work, it is likely faulty and will need to be replaced.

Replacing Your Rear Windshield Wiper Arm

If you have identified the issue and determined that replacement is needed, the next step is to obtain a new wiper arm. This can typically be done at a local parts store or online.

When replacing the wiper arm, follow these simple steps:

Remove the old wiper arm. This process will vary depending on your vehicle make and model, but generally, it involves loosening a few clips or bolts holding the arm in place. Install the new wiper arm. Once the old one is removed, carefully align the new one and secure it in place. Make sure all clips or bolts are tight and secure. Test the wiper arm to ensure it functions correctly. If the installation was successful, the arm should move smoothly and provide the necessary wiping action.

Professional Repair Services

If you are uncomfortable with the repair process or prefer a professional evaluation, take your vehicle to a certified mechanic or a specialized windshield wiper repair service. They have the expertise and tools to diagnose and fix the issue more accurately.

While some may suggest taking the wiper arm to a "rear arm windshield wiper doctor," it is more practical to take your vehicle to a professional for a thorough evaluation. They can ensure the wiper arm is properly installed and functioning, giving you peace of mind during your drive.

Lastly, consider replacing the entire wiper assembly, including the wiper blades, to ensure optimal performance. This can often be done simultaneously with or after replacing the wiper arm.

Conclusion

By following these steps, you can effectively troubleshoot and fix any issues with your rear windshield wiper arm. Whether you choose to replace it yourself or seek professional help, ensuring your visibility and safety while driving should always be a top priority.

Remember, clear visibility is crucial, especially during adverse weather conditions. Keep your rear windshield in top condition with regular maintenance and professional care when needed.
