Locating the Rear Wiper Blade
Identifying the rear wiper blade on your Toyota Sienna is a straightforward process. Begin by opening the rear liftgate, as it may be necessary for accessing the wiper blade. Next, locate the wiper arm, which is the metal piece that connects the wiper blade to the vehicle. The wiper arm is usually positioned at the top of the rear window, near the center.
Identifying the Wiper Blade Attachment Method
Once you have located the wiper arm, examine the method used to attach the wiper blade. There are two common attachment methods:
- Hook-style attachment: In this method, the wiper blade is attached to the wiper arm via a hook-shaped mechanism. To remove the blade, simply lift it up and pull it away from the wiper arm.
- Pin-style attachment: In this method, the wiper blade is secured to the wiper arm using a small pin. To remove the blade, gently press the release button or lever located on the wiper arm. This will disengage the pin, allowing you to slide the wiper blade off the arm.
Removing the Old Wiper Blade
Before replacing the rear wiper blade on your Toyota Sienna, you’ll need to remove the old one. Here’s how:

Installing the New Wiper Blade
Once you have removed the old wiper blade, it’s time to install the new one. Follow these steps to ensure a secure and effective replacement:
