- Prepare the Wiper Arm: If the wiper arm is secured by a nut, loosen it slightly but do not remove it completely. This creates a small gap for the removal tool.
- Position the Tool: Insert the tip of the wiper arm removal tool into the notch located at the back of the wiper arm base. Ensure the tool's offset provides leverage against the wiper arm post.
- Apply Leverage: Firmly press down on the tool's handle to apply upward pressure on the wiper arm. The arm should pop free from its post.
- Remove Nut and Arm: Once the arm is loose, fully remove the retaining nut and then carefully lift the old wiper arm off the post.
4.3. Wiper Arm Installation
- Clean the Post: Ensure the wiper arm post is clean and free of debris or corrosion.
- Position New Arm: Place the new Dorman 42694 wiper arm onto the post, aligning it correctly with the windshield's base. Ensure the wiper blade is in the correct resting position.
- Secure the Nut: Install the retaining nut onto the post and tighten it securely. Do not overtighten, as this can damage the splines or the arm.
- Test Functionality: After installation, test the wiper arm by activating the vehicle's windshield wipers to ensure proper movement and contact with the windshield.
5. Maintenance
Regular maintenance of your wiper system ensures optimal performance and longevity. Inspect the wiper arm periodically for signs of wear, corrosion, or damage. Ensure the wiper blade makes full contact with the windshield across its entire sweep. If the wiper arm appears bent or its spring tension is weak, it may need replacement.
6. Troubleshooting
- Wiper Arm Not Moving: Check if the retaining nut is securely tightened. If the arm is loose on the post, it may not engage properly.
- Wiper Arm Not Clearing Windshield: Ensure the wiper blade is new and correctly installed. If the problem persists, the wiper arm's spring tension might be insufficient, requiring replacement of the arm.
- Excessive Noise: Inspect the wiper arm and blade for proper alignment and tension. A worn or improperly installed arm can cause squeaking or chattering.
