In this video, see how to remove and replace the rear wiper blade on a Porsche Cayenne. Grip the metal rear arm with the plastic cover, pull the wiper blade as shown in the video until it disconnects from the clips (gently, to avoid breaking the arm), and detach it from the arm on the left. Install the new wiper blade onto the arm; you will hear a click when it is securely attached. Finally, lower the wiper arm onto the rear window and test the new blade's operation. It is always preferable to use original parts for better durability and quality.
