Description
Passenger seat heating switch for Peugeot 406
Replacement passenger seat heater switch (control button) designed for Peugeot 406 models. This genuine-style electrical switch restores reliable control of the seat heating function — ideal for workshops and DIY mechanics needing a direct replacement for a worn or faulty unit. The switch is commonly sought by its product code 6552LY and is suitable for technicians who value correct fitment and straightforward installation.
Key Features
– Direct replacement for the original seat heating control on the passenger side of Peugeot 406.
– OEM-style fit and connector for easy swap with the factory unit (product code 6552LY).
– Restores proper on/off control and temperature stage selection for the heated seat circuit.
– Durable construction designed for frequent use in daily-driven vehicles.
Compatibility and Fitment
Intended for: Peugeot 406 (passenger seat heater control). Always check physical match of the switch housing and electrical connector before installation. The unit is typically used where the original control has failed, the button is worn, or internal contacts no longer engage reliably.
Installation & Maintenance
Basic replacement procedure for experienced technicians and competent DIYers:
- Disconnect the negative battery terminal before starting any work on the vehicle electrical system.
- Remove the appropriate trim panel or center console surround to access the seat heater switch (use trim tools to avoid damage).
- Release the retaining clips securing the switch and carefully pull the module out of the mounting aperture.
- Disconnect the electrical connector from the back of the switch.
- Fit the new switch (6552LY) by connecting the plug, seating the unit in the aperture and locking the retaining clips.
- Reinstall trim, reconnect the battery and test the seat heating function on all switch positions.
In most cases this part is plug-and-play and requires no coding or programming. If uncertain about disassembly, follow the vehicle manufacturer’s service manual steps to avoid damaging trim or clips.

Why This Part Fails
Common failure causes for seat heater switches include:
- Wear of internal contacts from frequent use, leading to intermittent or no response.
- Accumulation of dirt, moisture or spillage around the switch that corrodes contacts.
- Mechanical damage to the button or housing from impact or aggressive removal.
- Electrical issues in wiring or connectors causing poor continuity to the heating elements (the switch itself is often blamed when connector/wiring faults exist).
Failures typically appear after many years of regular use or in vehicles with high mileage. Replacing the switch is often the fastest way to restore full function when the heating element itself remains operational.
Recommendations
- Inspect wiring and connector for corrosion or loose pins before fitting the new switch.
- Replace broken trim clips to ensure the new switch is securely mounted and sealed against dirt and moisture.
- Test the seat heating function through all switch positions after installation to confirm proper operation.
- For repeated failures, verify the seat heating element and wiring harness integrity with a multimeter.
