Description
Seat cushion adjustment controller for Citroën C8, Peugeot 807 and other models. Driver’s seat.
Product Overview
This replacement seat controller (seat switch) is designed for the driver’s seat and controls the cushion adjustment functions on Citroën C8 and Peugeot 807 vehicles. Supplied with genuine-style part numbers 944931700ZL / 6554H9, it is intended for workshops and experienced DIYers who maintain or repair PSA/Stellantis minivans.
How It Works
The unit operates the electric motors under the seat that adjust the cushion position — typically fore/aft, height and tilt depending on vehicle equipment. The switch translates driver inputs into electrical signals sent to the seat motors and position sensors, allowing precise and repeatable seat adjustment.
Typical Application And Fitment
Suitable For: Citroën C8 (Driver’s Seat), Peugeot 807 (Driver’s Seat). The item is commonly referenced by OEM codes 944931700ZL and 6554H9, so buyers often search by these numbers when sourcing a replacement.

Replacement Procedure (Summary)
Do the following or have a qualified technician perform the replacement: first disconnect the vehicle battery to avoid short circuits. Remove the seat trim panels to access the switch, unfasten the switch from its bezel or seat frame, unplug the electrical connector(s), and fit the new controller. Reconnect the connector, verify full function of all seat movements, and reassemble trim pieces. Finally, reconnect the battery and perform a final check of seat adjustment functions.
Installation Recommendations
- Disconnect the negative battery terminal before starting work.
- Inspect connectors and wiring for damage or corrosion; repair any brittle or exposed wiring before installing the new switch.
- Test the switch operation with the seat temporarily installed to confirm correct function before final reassembly.
- If seat motors do not respond, check fuses, relays and seat motor grounding points as part of fault-finding.
- For complex electrical faults or when additional coding is required, use qualified diagnostic equipment and procedures.
Why These Parts Fail
Seat switches are subject to frequent mechanical use and can fail for several reasons: worn internal contacts or potentiometers, ingress of moisture or dirt, connector corrosion, and physical damage from impact or excessive force. Heat from heated seats or spills can accelerate wear. Failures usually present as intermittent operation, loss of one or more adjustment directions, or a completely non-responsive switch.
Why Choose This Controller
Because this item is commonly listed under the OEM numbers 944931700ZL and 6554H9, it is a direct-fit option for workshops and DIYers seeking a like-for-like replacement. Replacing a faulty switch restores comfort and seat positioning safety for the driver.
Additional Notes
Careful inspection of the seat wiring harness and connector is recommended during replacement to prevent repeat failures. Keep the work area clean and follow the vehicle manufacturer’s safety precautions when removing and installing seats.
