Tools you'll likely need:
* Flat-head screwdriver: A sturdy, but not overly-sharp, one is best.
* Wrench (possibly): Some models require a wrench to loosen a nut under the wiper arm cap.
* Penetrating oil (optional): If the wiper arm is stuck, this can help loosen it.
* Shop towels or rags: To protect the paint.
Procedure:
1. Lift the wiper arm: Raise the wiper arm to its highest position. This provides better access.
2. Locate the nut or clip: Underneath the wiper arm cap (often a plastic piece), you'll find either a nut or a retaining clip. Inspect carefully to determine which type of fastener is holding the arm in place.
3. Remove the nut (if applicable): If there's a nut, use the appropriate wrench to carefully loosen and remove it. Be gentle to avoid stripping the threads.
4. Remove the clip (if applicable): If it's a retaining clip, usually a flat-head screwdriver is used to carefully pry it loose. You may need to insert the screwdriver's blade into a small slot or gap to release the clip. Again, be gentle to avoid breaking the clip or scratching the car.
5. Remove the wiper arm: Once the nut or clip is removed, you should be able to gently pull the wiper arm straight up and away from the windshield. It may be slightly stiff, so apply firm but controlled pressure.
Important Considerations:
* Penetrating oil: If the arm is difficult to remove, apply penetrating oil to the area around the fastener. Allow it to soak for a few minutes before attempting removal again.
* Wiper arm position: Take note of the wiper arm's position before removing it. This will help you reattach it correctly later.
* Paint protection: Protect the paint around the wiper arm with shop towels to avoid scratches.
* Force: Avoid excessive force at any stage. If it's unusually difficult, you might have missed a step or there could be an issue requiring further investigation.
* Reassembly: The reassembly process is the reverse of removal.
Disclaimer: This is general guidance. Incorrect removal could damage your vehicle. If you're uncomfortable with this process, consider taking your vehicle to a professional mechanic. They have the tools and expertise to do the job safely and correctly.
