Citroën Grand C4 Picasso Wiper System: A Comprehensive Guide

The Citroën Grand C4 Picasso is a compact MPV produced by the French automaker since 2014. It is renowned for its spacious cabin, advanced connectivity, and innovative features. Among its notable components is the wiper system, responsible for ensuring clear visibility during inclement weather conditions.

Automatic Wiper System

The Grand C4 Picasso features an automatic wiper system that detects the presence of rain and adjusts the wiper speed accordingly. The system utilizes a rain sensor mounted on the windscreen, which measures the amount of water on the glass. When the sensor detects moisture, it triggers the wipers to operate at the appropriate speed.

Adjustable Wiper Speed

The wiper speed can be manually adjusted by the driver using the dial located on the dashboard. There are multiple speed settings to choose from, allowing the driver to select the optimal setting for the current weather conditions.

Intermittent Wiper Function

The system also includes an intermittent wiper function that allows the wipers to operate at predetermined intervals. This function is particularly useful in light rain when it is not necessary to have the wipers operating continuously.

Washer Function

In addition to the wipers, the system also includes a washer function that sprays washer fluid onto the windscreen. The washer fluid helps to remove dirt and debris from the glass, ensuring optimal visibility.

Wiper Blades

The wiper blades are a crucial component of the wiper system. They are made from a durable material that can withstand the elements and provide effective cleaning performance. The wiper blades should be replaced periodically to maintain optimal performance.

Wiper Motor

The wiper motor is responsible for driving the wiper blades back and forth across the windscreen. It is a powerful unit that can operate the wipers at a variety of speeds. The wiper motor is located beneath the windscreen and is easily accessible for servicing.

Wiper Linkage

The wiper linkage is a mechanical assembly that transfers the motion from the wiper motor to the wiper blades. The linkage ensures that the wiper blades move smoothly and efficiently across the windscreen.

Wiper Pivot Point

The wiper pivot point is the location where the wiper blades connect to the wiper linkage. It is a vital point that allows the wiper blades to move in an arc across the windscreen.

Wiper Reservoir

The wiper reservoir is a container that holds the washer fluid. It is usually located in the engine bay and can be easily refilled when necessary.

Troubleshooting

If you encounter any issues with the wiper system in your Grand C4 Picasso, there are a few troubleshooting steps you can take.

 Check the wiper fuses to ensure they are not blown.
 Inspect the wiper blades for wear and tear.
 Ensure that the washer fluid reservoir is filled.
 Clean the rain sensor on the windscreen.
 If the issue persists, take your vehicle to a qualified mechanic for further diagnosis.

The Citroën Grand C4 Picasso wiper system is a sophisticated and effective component that contributes to the safety and visibility of the vehicle during inclement weather conditions. By understanding the key components and functions of the system, owners can ensure that it operates at its optimal performance and provides years of reliable service.
