Description
Steering column stalks, multifunction switch DELPHI COM2003 for Citroën and PEUGEOT vehicles. Controls fog lights, trip computer, front and rear wipers, rain sensor, trip computer, ESP, cruise control and car radio (radio control must be supplied or transferred).
Product Overview
This multifunction stalk (Delphi COM2003) is a direct-fit-style control module mounted on the steering column. It consolidates numerous driver controls—fog lamps, wiper systems (front and rear), rain sensor input, trip computer functions, ESP signals, cruise control activation and, depending on vehicle equipment, radio control. The radio control function may require transferring an existing radio stalk or adding the radio control element during installation.
Key Benefits
- Restores full steering-column control functionality in affected Citroën and Peugeot models.
- One compact unit replaces several individual switches, simplifying repairs.
- OE-style fitment and connector layout for straightforward replacement on compatible vehicles.
- Commonly searched by part numbers 96605599XT and 6242A4 — useful SEO keywords for mechanics and DIY enthusiasts.
Technical Information
- Manufacturer: Delphi (OE Supplier) / Compatibility with Stellantis Citroën & Peugeot
- Model: Delphi COM2003
- Product Codes: 96605599XT, 6242A4
- Other Numbers: NFP (as referenced in supplier listing)
Compatibility
Commonly fitted to a range of Citroën and Peugeot passenger cars. Examples include:
- Citroën: C5 I, C8, Berlingo II
- Peugeot: 206, 307 II, 406, 807
Compatibility depends on steering column variant, connector type and factory equipment level (e.g., presence of rain sensor, cruise control wiring, radio stalk). Verify part numbers against the vehicle’s existing switch before ordering.
Installation and Recommendations
Follow these steps and recommendations for a safe, reliable replacement:
- Always disconnect the negative battery terminal before starting work. Allow any residual power in the airbag system to dissipate per manufacturer guidelines.
- Set the front wheels straight and note steering wheel alignment marks. This helps avoid misalignment of the clockspring during reassembly.
- Remove the airbag and steering wheel following the vehicle maker’s removal procedure to avoid damage to the clockspring and connectors.
- Unplug the electrical connectors from the stalk assembly and remove mounting screws/clips. Transfer any radio control element if required by the vehicle’s configuration.
- Install the new stalk, reconnect connectors, and torque fasteners to the manufacturer’s specification. Refit the steering wheel and airbag, restoring battery connection last.
- After installation, verify the operation of all controlled systems: wipers (including intermittent and rain-sensor functions), fog lights, trip computer inputs, ESP warnings, cruise control engagement and radio controls (if applicable).
- If functional anomalies persist (for example, ESP or cruise faults), check wiring harness connectors and ground points. Some vehicles may require reinitialization of certain systems after component replacement.
Why This Part Commonly Fails
- High-Use Wear: Mechanical contacts and micro-switches inside the stalk degrade over time from repeated actuation.
- Moisture Ingress: Leaks at the windscreen/steering column or condensation can cause corrosion of contacts and short circuits.
- Electrical Stress: Faults in related wiring or switching heavy loads (e.g., repeated heavy wiper use) can damage internal contacts.
- Mechanical Damage: Rough handling during steering wheel removal or impact can break plastic levers or internal components.
- Connector Issues: Poor contact at multi-pin connectors causes intermittent behavior or loss of functions.
Practical Tips for Mechanics and DIYers
- Keep a clean work area and label connectors when removing multiple plugs to speed reassembly and avoid mistakes.
- If the vehicle has a rain sensor or automatic wipers, test sensor calibration after refit—some systems require a short drive cycle to self-calibrate.
- When transferring radio controls, ensure ribbon cables or flex connectors are undamaged and routed correctly to avoid pinching.
- Replace the stalk immediately at the first sign of intermittent function to prevent unintended activation of safety systems like ESP.
