Description
Steering column stalks Valeo Citroën C4 Picasso and Grand Picasso. They control fog lights, front and rear wipers, wiper sensor and on-board computer.
Product Overview
Multifunction steering column stalk assembly designed for Citroën C4 models (Picasso and Grand Picasso). This Valeo-style stalk integrates controls for fog lights, front and rear windshield wipers, the wiper/rain sensor and sends inputs to the on-board computer. Ideal for mechanics and DIY enthusiasts looking for a direct replacement using the original part numbers.
Function
The stalk assembly provides user controls and electrical switching for exterior lighting (including front and rear fog lamps where fitted), intermittent and continuous wiper functions, and the rain/wiper sensor input. It transmits position and switch signals to the vehicle’s electrical system and instrument cluster, allowing the on-board computer to display settings and activate corresponding actuators.

Compatibility
Fits Citroën C4 first generation variants including Picasso and Grand Picasso models where the above part numbers are specified. Always compare the physical connector and mounting arrangement to the original part before installation.
Common Failure Reasons
Stalk switches typically fail due to mechanical wear of internal contacts and microswitches, ingress of moisture or dirt causing corrosion, broken or fatigued levers from frequent use, or intermittent electrical contacts. Faulty connections can produce sporadic wiper or light operation, or error messages on the instrument cluster.
Installation Recommendations
Before starting, always disconnect the vehicle battery and wait a few minutes to avoid accidental airbag deployment and to protect vehicle electronics. Remove steering column trim covers to access the stalk unit—on some models partial steering wheel removal may be required. Unplug electrical connectors, remove retaining screws or clips, replace the stalk assembly, reconnect connectors and reassemble trims. After installation, verify all functions: wipers (including intermittent modes), rain sensor response, fog lights and instrument indications. If fault codes remain, perform diagnostic clearing and functional checks with appropriate workshop equipment.
Why Replace
Replace this unit when switches become unresponsive, when intermittent faults affect wipers or lights, when the stalk shows physical damage, or when diagnostic checks indicate internal contact failures. Timely replacement restores reliable control of lighting and wiper systems and prevents safety issues in poor visibility conditions.
Additional Notes
Part numbers and cross-references are provided to help locate the correct replacement. For a reliable fit, match the connector type and mounting points to the original unit. Professional installation is recommended if access requires steering wheel removal or if diagnostic recoding is necessary.
