Replacement Procedure

Basic replacement steps for the steering column stalk unit (general guidance for experienced technicians):

• Disconnect the negative battery terminal to prevent short circuits and airbag deployment.
• Remove the steering wheel trim and airbag module following manufacturer safety procedures.
• Unscrew the steering column covers to access the stalk mounting screws.
• Carefully unplug the electrical connector(s) from the existing stalk; note connector orientation and locking tabs.
• Unscrew and remove the old stalk assembly, then fit the replacement unit and secure with the original screws.
• Reconnect the electrical connector(s), reassemble column covers, airbag and steering wheel, then reconnect the battery.
• Verify all functions: fog lights, trip computer controls, rear wiper functions, rain sensor input and ESP indicators.

Installation Recommendations

• Work in a static-free environment and follow airbag safety rules when removing the steering wheel and airbag module.
• Use the correct Torx or Philips drivers to avoid stripping fasteners and ensure connectors are fully engaged.
• Inspect wiring harness and connector pins for corrosion or damage; clean contacts with appropriate electrical contact cleaner if needed.
• After fitment, run a full functional test and clear any fault codes with a diagnostic tool if required.

Most Common Failure Causes

• Mechanical Wear: Frequent use leads to worn internal detents and less firm switching action on used stalks.
• Electrical Contact Degradation: Oxidation or contamination of microswitch contacts causes intermittent or failed functions.
• Ingress Damage: Moisture from windscreen washing or rain sensor area can enter connectors and degrade electronics.
• Connector Fatigue: Repeated disconnection or poor seating can damage pins or locking tabs, creating intermittent faults.
• Age and Use: Components commonly show issues after many years or high mileage, especially in vehicles exposed to harsh environments.

Typical applications: Citroën C5 II and Peugeot 407 with ESP systems where a multi-function stalk controls fog lights, on-board computer inputs, rear wiper, rain sensor signals and ESP switch inputs. The part fits into the steering column assembly and connects via the original electrical connector — reference the vehicle’s connector shape and pin layout before installation.

Installation Recommendations

• Disconnect the negative battery terminal before starting to avoid short circuits and airbag deployment risks.
• Remove the lower steering column trim (usually retained with clips and screws) to access the stalk mounting points.
• Unplug the electrical connector(s) from the existing stalk—note connector orientation and any retaining tabs.
• Unscrew or unclip the stalk assembly from the column and replace with the COM2003 unit; ensure correct seating of locking tabs.
• Reconnect the electrical connector and reassemble the trim. Reconnect the battery and verify all functions (fog lights, trip computer inputs, rear wiper, rain sensor response and ESP indicator) before road testing.
• Use basic electrical contact cleaner on mating connectors if corrosion is present, and avoid forcing plastic clips to prevent breakage.

Why This Part Commonly Fails

Failures most often result from internal contact wear, moisture ingress or mechanical fatigue of plastic parts and detents. Frequent use, exposure to humidity and contamination from dust or liquids can cause intermittent electrical contacts or stuck switches. Mechanical stresses from repeated operation or brittle plastic ageing may lead to broken levers or retaining clips. In some cases, wiring or connector corrosion causes loss of function even though the stalk assembly itself appears intact.

Note: As a used component, physical wear signs may be visible (slightly loose detents or cosmetic marks), but the unit is supplied because it performs the required switch functions correctly.

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.

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

• Other Numbers: 6242S5, 6239JQ, COM2003
• Fitment: Citroën C5 II, Peugeot 407

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.
