Fitment And Replacement
Typical replacement procedure for an experienced mechanic or competent DIYer:
- Disconnect the negative battery terminal before starting work to prevent short circuits and protect vehicle electronics.
- Remove surrounding trim from the center console. This usually involves unclipping panels and removing a small number of screws—refer to a vehicle repair manual for exact trim removal points.
- Unscrew or unclip the heater control unit from the dash and carefully pull it forward to access the electrical connector.
- Unplug the connector and depress the retaining tab to release the faulty button from the control module.
- Install the replacement button by reversing the removal steps: insert the button, reconnect the electrical plug, refit the control unit and reassemble the trim pieces.
- Reconnect the battery and verify function of the switch, illumination and all heating/ventilation settings.
Installation Recommendations
- Always disconnect the battery before removing electrical components.
- Work on a stable surface with adequate lighting and use non-marring trim removal tools to avoid damage to panels.
- Check connector pins for corrosion or bent contacts and clean if necessary before refitting.
- Test functionality (fan speeds, temperature selection, illumination) before completing reassembly.
Why This Part Fails Most Often
The most common failure modes for heater control buttons are mechanical wear and electrical contact degradation. Repeated use causes internal contacts to lose conductivity or the plastic actuator to crack. Moisture ingress or spilt liquids from the passenger compartment can corrode contacts and damage the illumination lamp or LED. In some cases, poor connector seating or damaged wiring at the plug causes intermittent function.
Suitable For
Owners and workshops servicing first-series Citroën C1 and Peugeot 107 seeking a cost-effective repair for faulty heater controls. Part is typically searched by product code and model name, so reference 6451SK when ordering.
