Before beginning installation, ensure the vehicle's ignition is off and the wiper system is disengaged to prevent accidental activation.

4.1. Removing the Old Wiper Arm

Some wiper arms can be particularly stubborn to remove. A specialized wiper arm removal tool (such as Dorman 49023) can simplify this process. If your wiper arm has a notch at the back, this tool can be used for leverage.

Figure 3: Wiper arm base and pivot point

1. Locate the nut securing the wiper arm to the wiper post.
2. Loosen this nut slightly to allow for movement, but do not remove it completely yet. This creates a pivot point.
3. If using a wiper arm removal tool, insert its tip into the notch at the back of the wiper arm.
4. Use the tool to apply upward pressure, leveraging against the wiper post or the loosened nut, to dislodge the arm from its tapered shaft.
5. Once the arm is loose, fully remove the nut and then the old wiper arm.
