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. Check the connector for corrosion or bent pins before installing the new switch. If the seat still does not operate after replacement, verify fuses and motor operation with a multimeter before replacing additional components.

Reason For Failure

• Wear Of Internal Contacts – Frequent use leads to contact erosion and intermittent or lost function.
• Moisture Ingress Or Corrosion – Spills or humid conditions can corrode terminals and cause failure.
• 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.

This Seat Memory Controller (part number 6554H3) is a direct-fit electrical component used on Citroën C8 and Peugeot 807 vehicles to store and recall driver seat positions. It controls the memory function that saves preferred seat positions and communicates with the seat adjustment motors and the vehicle’s comfort electronics. The part is commonly referenced by its code 6554H3 and is sought after by professional workshops and DIY mechanics for reliable restoration of memory seat functionality.

Technical Information

Manufacturer: Citroën / Peugeot (Stellantis)

Model: Citroën C8; Peugeot 807

Product Codes: 6554H3

Additional Numbers: NFP

Function And Application

The controller stores multiple seat position presets and sends position commands to the seat motors when a preset is selected. It is mounted on or near the seat (side panel or under-seat area depending on model) and connects to the seat’s wiring harness. When functioning correctly, it enables quick recall of lumbar, backrest, and fore/aft positions for different drivers.

Common Symptoms And Failure Modes

• Loss Of Memory Function: Presets Are Not Saved Or Recalled.
• Intermittent Operation: Memory Works Sporadically, Often In Wet Or Corroded Conditions.
• Complete Failure: No Response From Memory Buttons While Manual Seat Adjustment Still Works.

Typical causes include connector corrosion, broken solder joints on the PCB, moisture ingress, wear from long service life, or damage from impact and seat movement. Electrical issues in the seat wiring (shorts/opens) or blown fuses can mimic controller faults.

Replacement And Installation

General Replacement Steps (Overview For Experienced Mechanics):

• Disconnect The Battery Before Any Work To Prevent Short Circuits And Protect Sensitive Electronics.
• Move The Seat To A Position That Gives Access To The Side Panel Or Under-Seat Trim.
• Remove Relevant Trim Panels And Unscrew The Controller Fasteners.
• Carefully Unplug The Multi-Pin Connector(s) From The Controller.
• Install The Replacement Controller, Reconnect Connectors And Secure Fasteners.
• Reconnect The Battery And Verify Memory Functionality By Programming And Recalling Presets.

Follow The Manufacturer’s Assembly Sequence Where Available And Avoid Pulling On Wiring. If The Connector Shows Corrosion, Clean Or Replace The Connector Before Final Installation.

Installation Recommendations

Always Work With The Battery Disconnected When Servicing Seat Electronics. Use Proper Trim Tools To Avoid Breaking Clips And Ensure Connectors Are Fully Seated. After Installation, Check All Seat Adjustment Functions And Program Memory Positions Per Vehicle Procedure. If The Memory Function Still Fails After Fitting A Known-Good Controller, Inspect The Seat Wiring, Fuses, And Related Comfort Modules.

Why This Part Commonly Fails

Seat Memory Controllers Are Regularly Exposed To Vibration, Moisture From Clothing Or Spills, And Mechanical Stress From Seat Movement. Over Time Solder Joints Can Crack, Connectors Can Corrode, And Internal Components Can Wear Out. High Mileage Vehicles And Cars That Have Experienced Water Ingress Or Interior Spills Are At Higher Risk Of Controller Failure.
