Description
Controller for seat heating for Peugeot 307 and 607.
Product Description
This seat heating controller is a direct-fit replacement designed for Peugeot 307 and Peugeot 607 models. Engineered for professional workshops and skilled DIY enthusiasts, the unit restores reliable control of the seat heating function, allowing step-less or multi-level heat adjustment depending on the original vehicle specification. The controller is compatible with the listed product codes and matches the original mounting and connector layout for straightforward replacement.
Key Benefits
- Restores full seat heating functionality—quickly returns comfort to the driver and passengers.
- OEM-fit dimensions and connector layout for easy installation without trimming or modification.
- Robust design suitable for workshop replacement and field repairs.
- Useful for mechanics and experienced DIYers searching by part number (see Technical Information).
How It Works
The controller switches and regulates current to the seat heating elements according to the user-selected setting. Depending on the original vehicle equipment, the unit may contain resistive switching stages or a small electronic regulator to provide multiple heat levels and protect the wiring from overload.
How To Replace
- Disconnect the vehicle battery before starting work to avoid short circuits.
- Remove the relevant trim panel or switch bezel around the seat heater control using soft trim tools to avoid damage.
- Unplug the electrical connector from the old controller and release any retaining clips or screws.
- Fit the replacement controller in the same orientation, secure fasteners, and reconnect the electrical connector.
- Reconnect the battery, check fuses related to the seat heating circuit, and verify operation through all heat settings.
Installation Recommendations
- Always disconnect the battery before removal and installation.
- Use plastic trim tools to avoid damaging interior panels and switch bezels.
- Inspect the wiring harness and connector for corrosion or damage; repair any degraded wiring before installing the new controller.
- Check seat heating fuses and related relays if the system does not operate after installation.
- Test all heat levels and confirm proper seating of connectors to avoid intermittent faults.
Why The Part Most Often Fails
- Worn or pitted switch contacts caused by repeated switching cycles.
- Moisture ingress or spilled liquids leading to corrosion of contacts and connectors.
- Overheating due to a short or excessive current draw from damaged seat heating elements.
- Mechanical damage during interior repairs or improper handling of the switch assembly.

Additional Notes
This controller is aimed at professional mechanics and experienced DIYers who are comfortable with interior disassembly and basic electrical diagnostics. Lifespan depends on vehicle usage and environment; failures commonly occur after many years of use or when exposed to moisture and contamination. Replacing the controller and addressing any underlying causes (damaged heating elements, corroded connectors) will help prevent repeat failures.
