Technical Information

• Manufacturer: Stellantis / Citroën Peugeot
• Model: Peugeot 3008 I (T84), Peugeot 5008 I (T87)
• Product Codes: 96738322XT, 6451Y3, 6452Y3
• Other Numbers: 6451Y3 | 6452Y3 | 96738322XT

Function

The unit controls heating and air conditioning functions: temperature setting, blower/fan speed, air distribution modes, recirculation, A/C compressor request and, where applicable, automatic climate regulation logic. It interfaces with vehicle sensors and actuators (thermosteps, blend/stepper motors, blower motor, refrigerant pressure switches) to maintain the selected cabin climate.

Signs Of Fault

• Unresponsive or intermittent buttons and knobs on the climate panel.
• Incorrect temperature regulation (heater or A/C not reaching requested temperature).
• Blower speed stuck at one level or not running at all.
• Erratic automatic climate control behavior or persistent error messages.
• Display failures or missing status indicators on the control unit.

Why This Part Fails Most Often

Common causes of failure include moisture ingress and corrosion of PCB tracks or connectors, worn encoder potentiometers and mechanical switches, cracked solder joints from thermal cycling, and connector pin corrosion. High mileage, prolonged exposure to cabin humidity (for example after water leaks) and heat stress accelerate wear. Failures are more likely in older vehicles or after repeated thermal cycles.

Installation Recommendations

• Safety First: Always disconnect the vehicle battery before starting to avoid short circuits and to protect electronic modules.
• Access: Removal typically requires removal of trim panels around the center console and dashboard, followed by unscrewing the climate control unit retaining screws and releasing wiring harness connectors.
• Tools: Use plastic trim tools to avoid damaging trim clips and a set of Torx/Phillips sockets as required by model fasteners.
• Connector Check: Inspect all harness connectors and pins for corrosion or bent pins before fitting the replacement unit. Clean or repair wiring as necessary.
• Testing: Reconnect the battery only after the unit is mechanically secured and connectors are fitted. Test all climate functions (fan speed range, temperature adjustment, A/C compressor engagement, vent selection) before reassembling trim.
• Final Check: Verify there are no persistent warning lights related to HVAC or climate control in the instrument cluster after installation.

Notes For Professionals And DIYers

This part number is commonly searched by mechanics and independent owners; verify the printed part numbers when matching replacements. While many HVAC control units are direct plug-and-play electrically, differences in software variants or vehicle equipment levels (manual vs. automatic climate control, presence of additional sensors) may affect fitment. Replace faulty units with care and ensure connectors are fully seated.
