Description
Heating and Air Conditioning Control For PEUGEOT 3008 And 5008 First Generation
This replacement heating and air conditioning control unit is a direct-fit solution for owners and professional mechanics servicing PEUGEOT 3008 and 5008 first-generation models. Designed to manage cabin temperature, fan speeds, air distribution and AC engagement, this unit restores precise climate control and improves driver comfort. Commonly searched by product codes 96738323XT and 6451Y4, it is ideal for workshops and DIY enthusiasts looking for a reliable HVAC control panel.
Function
The control unit governs the HVAC system: it interprets driver inputs (temperature, fan, mode), controls blower speed, operates blend/recirculation actuators, and sends commands to the air conditioning compressor/clutch and related relays. It works together with temperature sensors and cabin actuators to maintain selected climate settings.

How Replacement Is Done
Basic replacement steps used by professional garages and experienced DIYers:
- Disconnect the negative battery terminal before starting work.
- Remove the center console trim and any securing screws or clips to access the HVAC control panel.
- Unplug electrical connectors and release the unit from its mounting.
- Install the new unit, reconnect connectors and fasten screws/clips.
- Reconnect the battery and verify all HVAC functions (fan speeds, temperature control, AC engagement, recirculation and mode selection).
Installation Recommendation
Always disconnect the battery before removal and follow the vehicle manufacturer’s disassembly sequence to avoid damaging trim or electrical components. Check connector pins for corrosion or bent terminals and ensure secure, clean connections. After installation, verify full functionality across all modes and fan steps. If an HVAC-related fault code remains, use a suitable diagnostic tool to read and clear codes.
Why The Part Most Commonly Fails
- Wear On Controls And Potentiometers: Frequent use, worn encoder pots or switches can cause intermittent or lost control.
- Moisture And Condensation: Ingress of moisture can corrode contacts and cause electrical faults.
- Heat And Sun Exposure: Prolonged cabin heat can degrade plastics and electronic components.
- Connector Corrosion Or Poor Grounding: Electrical resistance at connectors leads to unreliable operation.
- Electrical Surges: Voltage spikes during jump-starts or charging faults can damage internal electronics.
Typical Service Life
Service life depends on usage, environment and vehicle maintenance. Many units remain functional for several years; however, age-related wear or environmental damage can lead to failure, commonly appearing after long service intervals.
Additional Notes For Mechanics
Include the product codes 96738323XT and 6451Y4 in searches and ordering to ensure compatibility. When replacing the unit, check adjacent HVAC actuators and fuses—faults elsewhere in the system can mimic control unit problems. For full diagnostics use professional PSA-compatible diagnostic tools where available.
