Seat Adjustment Controller For Citroën C8, Peugeot 807 And Other Models. Driver’s Seat
Used Seat Adjustment Switch (Part Numbers 944931700ZL, 6554H9) for Citroën and Peugeot vehicles. This electrical controller operates the driver’s seat cushion adjustment and is a common replacement part for C8 and 807 models. Ideal for professional workshops and experienced DIYers who search by part number to find a direct-fit solution.
Key Benefits
Direct-fit replacement for the original unit, restoring lost or intermittent seat adjustment functions. Searching by OE codes 944931700ZL or 6554H9 increases the chance of rapid compatibility match. Practical for mechanics and independent repairers who need a reliable switch to recover seat positioning without replacing the entire seat assembly.
How It Works
The switch controls the electrical motors that move the seat cushion (fore/aft and tilt depending on the vehicle’s equipment). When the switch is pressed, it completes the circuit to the seat motors, sending commands for movement. Failure of the switch typically results in no movement, intermittent operation, or movement in a single direction only.
How To Replace
Typical replacement steps (general guidance):
- Disconnect the battery before starting work to prevent short circuits and avoid affecting vehicle safety systems.
- Move the seat to an accessible position. Remove necessary trim panels or screws securing the switch bezel (trim removal tools and a small Torx or Phillips driver are commonly required).
- Unclip the switch from the trim panel and unplug the electrical connector.
- Install the replacement switch by plugging in the connector and securing the bezel/trim. Refit any removed panels and reconnect the battery.
- Test all seat adjustment directions to confirm normal operation.
Estimated time: 20–40 minutes depending on trim complexity. Difficulty: Low to moderate for a trained technician or experienced DIYer.

Installation Recommendation
Always disconnect the vehicle battery before removal and installation of electrical components. Use appropriate trim tools to avoid damaging plastic panels.

- Mechanical Damage – Broken plastic tabs or housing from impacts or improper removal.
- Wiring Or Connector Issues – Loose pins or damaged wiring can mimic switch failure.
Troubleshooting Tips
- Check related fuses before replacing the switch.
- Inspect the connector for corrosion and clean contacts if necessary.
- Measure voltage at the switch connector while operating to confirm signal presence to the seat motor.
