Description
Heating and air conditioning control for Peugeot 3008 and 5008 first generation
High-quality heater and climate control unit designed for Peugeot 3008 I and 5008 I. This control module manages cabin temperature settings, blower speed, air distribution, recirculation and air conditioning activation. Often searched for by product codes 96738322XT and 6451Y3, this unit is a common replacement for workshops and DIY mechanics restoring full functionality to the HVAC system.
Purpose-built for reliable operation in the vehicle interior, the module interfaces with temperature sensors, blower motor/resistor or blower motor controller, AC compressor clutch command, and various mode actuators. Replacing a faulty control unit typically restores user interface functions (knobs/buttons/display) and automatic climate control behavior when present.
Fitment: Direct fit for first generation Peugeot 3008 and Peugeot 5008 models. Because this part is commonly searched by reference numbers, use the codes when looking up compatibility in parts lists.

Installation Recommendations
- Always disconnect the battery before starting work to avoid short circuits or damage to electronic components.
- Remove surrounding trim panels carefully to access the HVAC control unit—use plastic trim tools to prevent breakage.
- Unplug electrical connectors gently and inspect pins for corrosion or bent contacts. Clean connectors if necessary and ensure secure seating on reassembly.
- Swap the unit, reconnect all plugs and verify operation before refitting trim. Test blower speeds, AC engagement, temperature adjustment and all buttons or rotary controls.
- If the vehicle has adaptive or automatic climate features, perform any recommended adaptation or calibration procedures described by the manufacturer after installation (consult official service documentation if required).
- When in doubt or if coding/calibration is required, have the final checks performed by a technician with suitable diagnostic equipment.
Why This Part Fails Most Often
- Moisture Ingress And Condensation: Interior humidity or small leaks can corrode connectors and PCB traces, causing intermittent faults.
- Wear Of User Interface Components: Repeated use of knobs, buttons and potentiometers leads to mechanical wear and contact failure.
- Faulty Solder Joints Or Aged Electronics: Thermal cycling and vibration over years can cause cracked solder joints or failing components on the control board.
- Connector Corrosion Or Poor Contact: Oxidised pins create high-resistance connections that cause loss of functions.
- Electrical Surges Or Short Circuits: Faults elsewhere in the HVAC circuit (blowers, resistors, fuses) can damage the control unit.
This control unit is an essential component for comfortable cabin climate control and is commonly replaced when user controls or automatic functions stop responding. Use the product codes above when searching to speed up finding the correct part for your Peugeot 3008 I or 5008 I.
