How to Unscrew the Rear Wiper Nut on a Citroen C4 Picasso

Model: Citroen C4 Picasso MK 1 - Years 2006-2013
Part: Windshield wipers

If you are here, you probably need to replace the rear wiper, as it is a mechanical component that tends to wear over time, requiring maintenance. However, you should know that it is possible to replace just the rubber instead of the entire wiper blade, saving a lot of time and money. You may also need to replace the entire wiper arm if it is broken or malfunctioning. After obtaining the new part, push from underneath the arm to release the cap as shown in the video. Using a socket, unscrew the nut found directly beneath the cap. Now, pull the part to be replaced towards you until it comes out of its seat. Insert the new part, screw in the bolt, and fit its cover.
