How do you change a rear window wiper arm in my Nissan x-trail?

To change the rear window wiper arm on your Nissan X-Trail, first, lift the wiper arm away from the glass. Locate the retaining nut at the base of the wiper arm and use a socket wrench to remove it. Once the nut is removed, gently pull the wiper arm off its spindle, then align the new wiper arm and press it onto the spindle. Finally, secure it with the retaining nut and lower the arm back into its resting position.
