Fitment And Compatibility
Fits Peugeot 407 models equipped with an electric driver’s seat. Confirm that the part numbers match the one being replaced. This control assembly is typically used on left-hand drive and right-hand drive variants where factory electric seat adjustment was fitted.
Function And Application
The unit provides user control of the driver seat position by sending commands to the seat motors and sensors. Typical functions include:
- Fore and aft movement
- Seat height adjustment
- Seat cushion tilt
- Backrest recline
- Control of lumbar support where fitted
These controls ensure ergonomic driver positioning and may interface with other vehicle comfort systems depending on the vehicle specification.
Common Faults And Why The Part Fails
Failures usually arise from electrical and mechanical wear rather than the plastic trim itself. Typical causes include:
- Connector corrosion or poor contact due to moisture ingress or dirty pins
- Wear of internal switch contacts from frequent use leading to intermittent operation or complete failure
- Motor overloads or short circuits in the seat motors feeding back into the control switch/module
- Damage from impact, spills, or foreign objects trapped under the seat
Regular inspection of connectors and ensuring the seat rails are free to move help reduce premature faults.
Installation Recommendations
Recommended installation steps for experienced technicians and competent DIYers:
- Disconnect the vehicle battery before starting to avoid short circuits and to protect vehicle electronics.
- Move the seat to an accessible position, remove plastic trim covers and unbolt the seat from the floor rails as required.
- Carefully disconnect the multi-pin connectors and note any locking tabs; inspect pins for corrosion or damage.
- Replace the control unit or switch assembly, connect connectors firmly, and secure all fasteners and trim pieces.
- Reconnect the battery and test all seat functions for full range of movement before re-installing the seat completely.
For workshop safety follow the vehicle manufacturer’s assembly instructions and torque settings where applicable.
