Tools You'll Need:
* Flat-head screwdriver (or a wiper arm puller): A wiper arm puller is the safest and easiest option, but a sturdy flat-head screwdriver will work in a pinch.
* Shop towels or rags: To protect the paint.
* Penetrating oil (optional): If the wiper arm is particularly stubborn.
Procedure:
1. Park the vehicle: Ensure the vehicle is parked on a level surface and the ignition is off. Disconnect the negative battery cable as an added precaution against accidental shorts.
2. Lift the wiper arm: Raise the wiper arm away from the windshield. This allows better access to the attachment point.
3. Locate the wiper arm nut: Underneath the wiper arm, you'll find a nut or a small bolt securing the arm to the wiper transmission. This is usually hidden under a small plastic cap that may need to be carefully pried off.
4. Apply penetrating oil (optional): If the nut or bolt is difficult to loosen, spray some penetrating oil on it and let it sit for a few minutes.
5. Loosen the nut/bolt: Use the flat-head screwdriver (or wiper arm puller) to carefully loosen and remove the nut or bolt. If using a screwdriver, place it under the wiper arm and lever it carefully to avoid scratching the paint. A wiper arm puller fits over the arm and applies pressure to remove it.
6. Remove the wiper arm: Once the nut/bolt is removed, the wiper arm should come off easily. If it's stuck, gently wiggle it back and forth while pulling it up. Be careful to avoid damaging the wiper arm or the windshield.
7. Clean up: Clean the area and replace the plastic cap (if applicable).
Important Considerations:
* Wiper Arm Puller: Using a wiper arm puller is strongly recommended as it's designed for this task and minimizes the risk of damage to the wiper arm or the vehicle.
* Stubborn Arms: If the arm is extremely stubborn, consider seeking professional assistance. Forcing it can result in damage.
* Safety First: Always prioritize safety. Wear safety glasses if needed.
Replacing the Wiper Arm: The installation process is simply the reverse of the removal process. Make sure the new wiper arm is properly seated and the nut/bolt is tightened securely.
