High-quality replacement multifunction stalks designed for workshops and experienced DIYers who maintain Stellantis vehicles. These original-style Valeo COM2003 switches restore full control over exterior lighting, wipers and onboard functions while matching original electrical interfaces. Ideal when searching by part number — customers frequently look for 96496662XT, 6242S5, 6239JQ or COM2003.

Technical Information

• Manufacturer: Valeo
• Model: Citroën C5 II, Peugeot 407
• Product Codes: 96496662XT, 6242S5, 6239JQ
• Other Numbers: COM2003, 96496662XT/6242S5/6239JQ

Function

Multifunction stalk assembly controls fog lights, trip computer inputs, rear wiper operation, rain sensor input and the ESP-related switch function. The module transmits switch signals to the vehicle’s body control unit and driver information systems. On these models the stalk integrates mechanical detents and electrical contacts to deliver tactile feedback for each function.

Installation Recommendations

Before any work, disconnect the negative battery terminal and wait at least 10 minutes to allow the airbag system to de-energize. Remove the steering column trim panels to access the stalk connectors. Unplug electrical connectors and release retaining clips, then remove the old stalk and fit the replacement in reverse order. Check all functions (lights, wipers, trip computer, rain sensor and ESP switch) after reassembly. If unsure about airbag or steering wheel procedures, have the replacement performed by a professional.

Why It Fails Most Often

Failures typically stem from mechanical wear of the internal detents and springs, contaminated or oxidized electrical contacts, moisture ingress and repeated heavy use. Common symptoms include intermittent operation, loose or sticky stalk feel and loss of specific functions (e.g., intermittent wiper or fog light operation). Because this is a used unit, a slightly reduced tactile firmness compared to new parts is normal.

Practical Notes For Buyers

Part is suited for professional repairs or experienced DIY replacement on Citroën C5 II and Peugeot 407 cars equipped with the COM2003 stalk. Search by the listed part numbers to find this exact reference quickly. After fitting, verify all switch positions and error messages on the instrument cluster to ensure correct communication with vehicle systems.

Multifunction steering column stalk (combination switch) designed for Stellantis models, offering control over exterior lighting, onboard computer functions, rear wiper and rain sensor inputs, and the ESP interface. This unit is a direct-fit used replacement for Citroën C5 II and Peugeot 407 vehicles and is frequently searched for by part numbers such as 96592426XT, 6242S5 or 6239JQ — include these references when looking up compatibility or ordering.

For professional mechanics and DIY enthusiasts, this stalk provides a cost-effective option to restore full functionality of the vehicle controls without replacing the entire steering column module. Because it is a used item, expect cosmetic wear and slightly reduced mechanical stiffness compared with a new original part; electrical functions are reported to operate correctly.

Installation Recommendations

• Disconnect the vehicle battery and wait at least 10–15 minutes before starting work to reduce the risk of airbag deployment and to clear residual system voltage.
• Remove the lower and upper steering column trim to access the stalk mounting screws and electrical connector. In some cases the airbag or steering wheel may need to be loosened or removed — follow vehicle manufacturer procedures and torque specifications.
• Unplug the electrical connector(s) carefully and note any locating tabs or alignment pins before removing the old stalk.
• Fit the replacement unit in the reverse order: secure mounting fasteners, reconnect wiring, reassemble trims and reconnect the battery. Verify all functions (indicators, wipers, fog lights, trip computer controls, rain sensor response, ESP signals) before returning the car to service.
• Use genuine replacement fasteners where required and check for any stored fault codes after installation; clear codes if appropriate and test drive to confirm correct operation.

Most Common Failure Reasons

• Contact Wear: Repeated use causes contact pitting or loss of conductivity, leading to intermittent function of indicators, wipers or other switches.
• Mechanical Fatigue: Plastic detents, levers or return springs can wear or break, which reduces stiffness and tactile feedback.
• Moisture and Corrosion: Water ingress or condensation can corrode connectors and internal contacts, causing electrical faults.
• Electrical Arcing: High-current loads (e.g., fog lights) can produce arcing at worn contacts, accelerating failure.
• Impact Damage: Collisions or rough handling during previous repairs can misalign or crack components inside the stalk assembly.

If you are replacing a malfunctioning stalk, matching the part numbers listed above increases the likelihood of correct fitment. This unit is recommended for technicians and experienced DIYers familiar with steering column work and airbag safety procedures.
