Air conditioning and heating control with the first generation Citroën C1 and Peugeot 107 by 2014. It is a manual air conditioning panel with mechanical bowden, ideal as a substitute for a worn or stiff control.

The

panel is designed for cars with manual air conditioning (not digital automatic). Thanks to the original design and corresponding product codes, they fit both in size and electrically, connectors and attachment correspond to the serial part. Included are rods that ensure accurate movement of movement to mixing and distribution flaps.

Typical defects of the original part include pulled or broken rods, cracked plastic segments of the driver, stiff flaps causing stiff operation, or inoperative undercoat. Replacement of the complete panel with pulls to get a smooth operation of the control wheels and reliable temperature switching and flow direction.

Mounting tip: Remove the center panel panel, disconnect the electric connectors (fan, A/C), release three bowden rods (temperature, air distribution, recirculation) and screws holding the panel. When mounting a new piece, make sure the rods of the rods to the controls to ensure the full movement of the movement. Recommended work time approx. 0.5–1 hours according to experience. Test the flow of all functions before closing the dashboard.

Compatibility corresponds to models by 2014 (first generation) with manual control of air conditioning and heating. To be sure, check the conformity by code on your original episode – the fastest way to prevent confusion.

Original heating & air conditioning control panel designed for the first generation Citroën C1 and Peugeot 107 with manual climate control. This OEM panel provides mechanical controls for temperature, airflow direction and A/C activation. Commonly sought under part numbers 55900-0H0040, 55900-0H0020, 6452P6 and 6451SF for direct replacement when the factory unit becomes stiff or damaged.

Key Features

• OEM original unit compatible with Citroën C1 I and Peugeot 107 I (first generation)
• Mechanical control panel using cable (bowden) actuation for temperature, vent selection and A/C
• Smooth rotary/sliding controls and working detents; electrical connector present for A/C switch illumination
• Delivered as a used original part in excellent condition with intact cable stops; control cables are not supplied

Condition And What Is Supplied

This listing is for a used OEM heating & air conditioning control panel in excellent condition. Plastic cable stops (end-stops) are intact and the control knobs operate smoothly with reliable detents. The electrical connector for the A/C pushbutton and illumination is intact and ready to plug in. Please note: the control cables (bowdens) themselves are NOT included in the delivery.

Function And Common Failures

The panel mechanically operates temperature blend doors, vent selection flaps and the A/C on/off command via Bowden cables. Common faults on these models include broken plastic stops, weakened or seized control cables and worn detents, which lead to stiff operation, inability to change vent direction or loss of temperature control. Replacing the complete panel is a reliable way to restore precise, smooth control when individual cables or mounts are failing.

Installation Tips

Access is through the center dashboard trim. Remove the radio/vent frame, undo the fasteners holding the control panel, disconnect the electrical connector and release the cable clips. When refitting, set the levers and doors to their extreme positions (e.g. full cold and front vent) before attaching the cables so the travel and stops align correctly. Ensure all cable clips are seated and cables are not kinked. Check operation of each control and the A/C switch before refitting trim panels.

Compatibility

Intended for first-generation Citroën C1 I (2005–2014) and Peugeot 107 I (2005–2014) equipped with manual climate control. Always verify fitment by comparing OEM part numbers or checking your vehicle VIN if unsure.

Function And Benefits

This heating control operates the HVAC cable system that selects airflow direction and controls heater flap positions. It provides a tactile and reliable interface for temperature and vent selection, using mechanical cable linkages rather than complex electronic actuators—an advantage for straightforward diagnostics and repair. Replacing a faulty control restores proper airflow selection, improves cabin comfort and prevents uncontrolled vent positions or rattling caused by broken internal plastics or frayed cables.

Replacement Procedure

• Disconnect the negative battery terminal before starting to avoid electrical faults or short circuits.
• Remove the necessary dashboard trim panels to access the heater control unit (usually lower center console trim and surrounding bezels).
• Note the routing and attachment points of the control cables. Release the cable ends from the levers, then unfasten the control unit mounting screws.
• Install the replacement unit in reverse order: secure the unit, attach and adjust the cables so they move smoothly without binding, then refit trim panels.
• Check all HVAC functions: mode selection, recirculation (if applicable), and that cables operate smoothly through their full travel.

Installation Recommendations

• Always disconnect the battery before removal and installation to prevent damage to electrical components and ensure safety.
• Handle plastic levers and cable end stops carefully to avoid breaking brittle parts—older plastic can be fragile.
• Lubricate cable sleeves lightly if they are dry, and ensure cables run without sharp bends or chafing points.
• Verify full range of motion after installation; if any binding or unusual resistance is detected, recheck cable routing and secure fastenings.
• Keep replacement parts and fasteners original or OEM-equivalent to maintain correct fit and function.

Why This Part Fails Most Often

• Mechanical Wear: Cable ends, plastic levers and internal detents wear over time, leading to slack, slipping or broken connections.
• Cable Damage: Frayed or seized control cables prevent smooth operation and are a frequent cause of faulty vent selection.
• Plastic Degradation: Heat cycles and UV exposure make plastic components brittle, causing snaps or loss of indexing accuracy.
• Contamination: Dirt and debris accumulated in the control assembly cause stiff movement and accelerated wear.

This heater control is an effective direct-fit replacement for vehicles listed above and is particularly useful for workshops and self-repairers seeking a durable mechanical solution to HVAC control faults. Check the product codes against the vehicle’s parts list when ordering to ensure correct fitment.
