Description
Heating and manual air conditioning control complete with linkages for Citroën C1 and Peugeot 107 up to 2014
Overview
This complete heater and manual climate control unit with linkages is a direct-fit replacement for Citroën C1 and Peugeot 107 models produced until 2014. Designed for workshop technicians and competent DIYers, the unit controls temperature, airflow distribution and fan speed and provides direct mechanical actuation of blend and flap positions via supplied cables. Many customers search by part number—include the reference codes in your lookup to find the correct item quickly.
Features And Function
- Manual temperature control and fan-speed adjustment for reliable cabin comfort.
- Mechanical linkages (cables) for flap and blend control—robust replacement for worn or broken originals.
- Integrated switches for recirculation and A/C compressor engagement where applicable.
- Simple, serviceable design that allows targeted replacement without replacing the whole HVAC assembly.

Compatibility And Notes
Fits Citroën C1 and Peugeot 107 versions up to model year 2014 that use manual climate controls with cable-actuated flaps. Confirm fitment by matching the product codes listed above with the original part number. This assembly replaces both the control unit and the associated linkages, making it ideal when cables are snapped or internal controls are worn.
Installation Recommendation
- Always disconnect the battery before starting work to avoid electrical short circuits and protect vehicle electronics.
- Remove the center fascia trim carefully to avoid breaking plastic clips. Use appropriate trim tools and keep screws and clips organized.
- Label or photograph cable routing and connector positions before removal to ensure correct reassembly.
- Disconnect electrical connectors and unclip cable ends from the control levers. Replace linkages into their correct mounting points—do not force them; they should seat smoothly.
- After installation, verify all functions (temperature range, fan speeds, flap positions, recirculation and A/C switching if present) before refitting the trim.
- If in doubt about trim removal or electrical connections, have the work performed by a professional workshop.
How The Part Commonly Fails
Failures are usually mechanical or electrical in nature: plastic cables and levers become brittle with age and can snap; internal potentiometers or sliders wear out causing intermittent or stuck temperature and fan controls; dust and dirt build-up can impede smooth movement; and sun exposure accelerates degradation of plastic components. These issues typically appear on higher-mileage or older vehicles and often present as stuck flaps, missing fan speeds or inability to change temperature smoothly.
Why Buy This Replacement
Replacing the complete control assembly with linkages restores reliable manual control of HVAC functions without the need to overhaul the heater box. The unit is aimed at mechanics and equipped DIYers who want a direct-fit, serviceable solution that addresses both electrical and mechanical wear in a single replacement.
Useful Tips
- Check connector pins for corrosion and clean contacts if necessary before installation.
- Test the unit on-bench (where possible) for basic functionality before final installation.
- Keep original breakable clips and routing clips as reference or replace them during reassembly to ensure secure cable routing.
- Search online and in catalogs using one of the product codes for faster cross-referencing.
