Fitment And Typical Symptoms
This button is intended for the first-generation Citroën C1 and Peugeot 107. Common symptoms indicating a faulty heating control button include unresponsive or intermittent operation, a button that sticks or does not engage, failure of internal illumination, or erratic behaviour of the heating/ventilation control related to that specific switch.
Replacement And Installation
- Disconnect the vehicle battery before starting removal to avoid short circuits and prevent damage.
- Remove the centre console trim using appropriate plastic trim tools to avoid breaking clips or scratching panels.
- Unscrew or release the retaining clips holding the control module; carefully pull the module forward to access the connector.
- Unplug the multi-pin electrical connector from the back of the button assembly and remove the old switch.
- Install the new heating control button, reconnect the electrical connector and test the function and illumination before reassembling the trim.
- Reassemble trim and reconnect the battery. Verify full functionality with the vehicle running if required.
Why The Part Commonly Fails
- Mechanical Wear: Repeated use over many years can wear the internal actuator and latching mechanism.
- Electrical Contact Degradation: Oxidation or pitting on contact surfaces can cause intermittent or failed operation.
- Environmental Damage: Moisture ingress, spilled liquids or corrosion can impair switch function and illumination.
- Plastic Fatigue: Age-related brittleness may cause housing clips or button elements to crack or break during use or removal.
Installation Recommendations
- Always disconnect the battery before removal and follow the vehicle manufacturer’s disassembly sequence to prevent damage to surrounding components.
- Use non-marring plastic trim tools to remove panels; avoid excessive force on clips and connectors.
- Inspect the wiring harness and connector for corrosion or damage; clean contacts if necessary before installing the new switch.
- After fitting, verify all functions (switch response, illumination and related HVAC behaviour) before completing reassembly.
If you are replacing a worn or failed button from a first-series Citroën C1 or Peugeot 107, reference the product code 6451SK when ordering to ensure correct fitment.
