Description
Heating and air conditioning control for Citroën C8 and Peugeot 807 vehicles from 2005.
This HVAC/heater control panel is designed for Citroën C8 and Peugeot 807 models and is intended for professional mechanics and experienced DIY enthusiasts. The control regulates cabin temperature, blower speed, air distribution and air conditioning functions, restoring full manual control of the climate system. The part is frequently searched for by its product numbers, so check the codes below when locating the correct replacement.
Built to replace the original dashboard control unit, this module offers straightforward functionality with tactile buttons and rotary controls typical for early 2000s Stellantis vehicles. Replacing a faulty control restores comfort and prevents unintended heating or cooling behaviour caused by worn switches or electrical faults.
Technical Information

Installation Recommendation
- Disconnect the negative battery terminal before starting to avoid short circuits.
- Carefully remove the surrounding trim panels and fascia screws to access the control unit; use appropriate trim tools to avoid breaking clips.
- Unscrew the control unit, release and carefully unplug all electrical connectors. Inspect connector pins for corrosion or bent contacts.
- Install the new control unit, plug connectors firmly into place and test all functions (blower speeds, temperature adjustment, air distribution modes, AC on/off, recirculation) before reassembling the dashboard.
- Reattach trim panels and reconnect the battery. Verify that no warning lights remain and that all HVAC functions operate smoothly.
Why The Part Fails Most Often
- Wear Of Mechanical Controls: Rotary knobs and internal potentiometers wear over time, causing intermittent or lost functions.
- Moisture And Corrosion: Water ingress or condensation can corrode contacts and circuit traces inside the unit.
- Heat And Vibration: Long-term exposure to heat and vibration can create cracked solder joints or failed electronic components.
- Connector Problems: Loose or corroded connectors may cause erratic behaviour even when the control panel appears intact.
Typical Replacement Interval
There Is No Fixed Service Interval. Many Units Last Over A Decade, But Failures Become More Likely With Age, High Mileage, Or Exposure To Damp Conditions. Consider Replacement When Controls Become Intermittent, Unresponsive, Or When Multiple Functions Stop Working.
