How do you remove rear wiper arm from Peugeot 407 estate?

To remove the rear wiper arm from a Peugeot 407 estate, first, lift the wiper arm away from the rear window. Look for a small securing nut at the base of the arm and use a suitable socket or wrench to loosen and remove it. Once the nut is removed, gently wiggle the wiper arm to detach it from the splined shaft. Be cautious not to damage the shaft or the rear window during the process.
