Tools You'll Need:
* Wrench (likely 10mm or 11mm): Check your owner's manual or look at the nut on the wiper arm to determine the correct size. A socket wrench is preferable to an open-ended wrench for better grip and control.
* Penetrating oil (like PB Blaster or WD-40): This helps loosen any rusted or seized nuts.
* Cloth or rag: To protect the windshield and wiper arms.
* Flathead screwdriver (optional): In case the nut is extremely stubborn.
Procedure:
1. Prepare the Wiper Arms: With the ignition off, park the vehicle and set the parking brake. Spray penetrating oil onto the nut where the wiper arm connects to the wiper spindle. Let it sit for 10-15 minutes to soak in and loosen any corrosion.
2. Position the Wiper Arm: The key is to lift the wiper arm to where it's approximately perpendicular to the windshield. This helps give you better access to the nut and reduces strain on the arm. Sometimes you can rotate the arm to reach a more accessible spot. Caution: You might need to slightly maneuver the arm. However, do not force it to an unnatural position, as this could break it.
3. Remove the Nut: Carefully use your wrench to remove the nut securing the wiper arm to the wiper spindle. Turn the nut counter-clockwise. If the nut is very tight or frozen, you may need to apply more penetrating oil and let it soak some more. Avoid using excessive force that could strip the nut or break the wiper arm. If the nut is really stuck, a very gentle tap with a hammer on the wrench can sometimes help break it free. If it is truly seized, a flathead screwdriver placed on the wrench might provide extra leverage, but be very careful not to damage the arm or spindle.
4. Remove the Wiper Arm: Once the nut is off, the wiper arm should pull straight off the wiper spindle. It might require a gentle tug. Sometimes there is a small retainer clip hidden under the nut; If it resists, check for it.
5. Repeat for the Other Arm: Repeat steps 1-4 for the second wiper arm.
6. Clean Up: Clean the area around the spindle once the wiper arms are removed.
Important Considerations:
* Rust and Corrosion: On older cars like a 1993 Voyager, rust and corrosion are common culprits for difficult nut removal. Be patient and use penetrating oil liberally.
* Force: Never use excessive force. If something feels like it's going to break, stop and reassess your approach. If needed, seek professional help to avoid further damage.
* Wiper Spindle: Be careful not to damage the wiper spindle itself during removal.
If you're uncomfortable performing this task, it's best to take your vehicle to a mechanic or auto parts store where they can remove the wiper arms quickly and safely.
