Description
Heating and Air Conditioning Control for PEUGEOT 308 T7 vehicles.
This HVAC control panel is a direct-fit control interface for Peugeot 308 (T7) models, providing intuitive control over heating, ventilation and air conditioning functions. Designed for professional workshops and experienced DIY mechanics, the unit is often searched by its product codes (96718462XT, 96718462XT-00, 6452S2). The clear layout and robust connectors make it a common replacement part when the original control stops responding, displays faults, or loses certain functions.
Function And Application
The unit governs cabin temperature, air distribution, fan speed, air recirculation and air conditioning engagement. It interprets user inputs and sends commands to the blower motor, blend/stepper motors (or servos), AC compressor clutch and related climate actuators. The panel usually includes an integrated display or LED indicators and electrical connectors that communicate with the vehicle’s climate and body control systems.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot) / Valeo
- Model: Peugeot 308 T7
- Product Codes: 96718462XT, 96718462XT-00, 6452S2
- Additional Numbers: 96718462XT-00 (alternate listing), 6452S2 (manufacturer/variant code)
Installation Recommendations
Before starting any work, disconnect the negative battery terminal to avoid short circuits and accidental airbag deployment. Typical replacement steps:
- Remove surrounding dashboard trim panels using proper plastic trim tools to avoid damage.
- Unscrew the retaining screws securing the control unit and gently pull the panel forward.
- Disconnect electrical connectors by releasing locking tabs—inspect connectors for corrosion or broken pins.
- Fit the replacement unit, reconnect all plugs and reassemble trim. Verify full function of all HVAC modes and fan speeds.
Most units are plug-and-play. However, if the vehicle has climate functions integrated with other modules, a diagnostic scan or reinitialisation may be required to restore full operation. For complex cases, use professional diagnostic equipment.
Why This Part Fails Most Often
- Wear Of Controls: Repeated use can wear potentiometers, switches or rotary encoders, causing intermittent or lost control of fan speed and temperature selection.
- Moisture And Contamination: Spills or moisture ingress may corrode contacts or damage internal electronics.
- Connector Issues: Broken pins, loose connections or oxidised terminals cause communication faults between the panel and climate actuators.
- Display/Backlight Failure: LED or display components can fail, making settings unreadable though functions may still work.
Practical Tips For Mechanics And DIYers
- When diagnosing, check fuses and wiring to the blower motor and sensors before replacing the control unit to avoid unnecessary swaps.
- Compare product codes on the faulty unit with the replacement to ensure identical electrical connectors and feature set.
- Keep a clean work area and label connectors if you remove multiple plugs to prevent misrouting on reassembly.
