Description
Set of heating and manual air conditioning linkages for Citroën C1 and Peugeot 107 up to 2014.
Product Overview
This replacement kit contains the linkage rods and cables for the heating and manual air conditioning controls on Citroën C1 and Peugeot 107 models. Designed for workshops and DIY mechanics, the kit restores accurate, smooth operation of the HVAC control panel when original rods have become worn, seized or broken. Commonly searched by part numbers 6451SG, 6451SJ and 6451SH.
Why Fit This Kit
- Restores full control of temperature and airflow flaps for manual climate systems.
- Eliminates sticking controls, inaccurate temperature selection and detached control rods.
- Direct fit for Citroën C1 and Peugeot 107 — straightforward replacement for workshop or competent DIY.
Function And Typical Faults
The linkages transfer movement from the dashboard control unit to the heater/ventilation flaps and blend doors inside the HVAC box. Failures occur because plastic joints and cable ends wear, metal rods corrode or cable sheaths crack, which leads to slack, sticking or complete loss of control. Problems are more likely on older cars or vehicles exposed to moisture, road salt and high mileage.
Replacement Guide
Basic steps for replacement (for experienced mechanics and competent DIY):
- Park the vehicle on a level surface and isolate ignition. Disconnect the negative battery terminal if working near electrical components or airbags.
- Remove glovebox or lower dash panels to access the HVAC control unit and cable routing.
- Note or mark the original routing and control lever positions to ensure correct reassembly.
- Unclip the old rods/cables at the control unit and at the HVAC actuators. Remove any retaining clips or fasteners.
- Install the new linkages following the original routing. Secure clips and ensure cables move freely without binding.
- Test all control functions (temperature, airflow direction, recirculation if applicable) before final reassembly. Adjust cable ends for neutral/zero play where possible.
- Reinstall trim and glovebox, reconnect battery and perform a final functional check.
Use light silicone spray or appropriate lubricant on moving connections if needed. Avoid heavy grease inside the HVAC box that could attract dirt.

Mounting Recommendations
Work In A Clean Area: Keep HVAC components and cables free of dirt during installation. Check cable routing for chafing and secure with original clips. Ensure control levers return smoothly through their full travel. After fitting, operate the heater controls through all positions to confirm correct movement of flaps and blend doors. If any electrical actuators are present, verify their function before completing reassembly.
Most Common Cause Of Failure
Wear And Environmental Damage: Plastic joints and cable ends wear out over time and exposure to heat, moisture and contaminants. Corrosion of metal rods and binding of cable sheaths are frequent causes of poor or lost control. Sudden failure is often due to broken cable ends or snapped plastic connectors.
