Part description

This is a used heating and air conditioning control (HVAC control panel) for a Peugeot 207. Parts of this type are often searched for by number, so when comparing, please mention in particular the designation 69910002 and the PSA code series 6451TK / 6451TL. A suitable solution for non-functioning buttons/controllers, fan control failures or problems with temperature and flow direction regulation.

Technical information

• Manufacturer: VALEO
• Model: Peugeot 207
• Other numbers: 6451TK, 6451TL

Product codes

• Product codes: 69910002, 6451TK, 6451TL

Installation recommendations

• Please compare the codes on your original controller with the numbers listed (69910002, 6451TK/6451TL) before assembly.
• Proceed with care during disassembly due to plastic handles and connectors; do not apply unnecessary pressure to the front panel.
• After plugging in, check the functions: response of buttons/controllers, change of fan speed and switching of flow modes.

Reasons why the part is damaged

• Wear of contacts and buttons due to frequent use (insensitive or missing controls).
• Intrusion of dust and dirt into the mechanism of controls and connectors.
• Voltage fluctuations or bad contacts in the electrical installation leading to function failures.
• Mechanical damage during unprofessional disassembly of the dashboard or handling of connectors.

Overview

This OEM-compatible heating and air conditioning control unit is designed for the Peugeot 207 and provides reliable manual control over cabin temperature and airflow direction. Ideal for professional mechanics and DIY enthusiasts, the unit is commonly searched by product codes and part numbers (see Technical Information). It restores precise control of blower direction, temperature selection and AC on/off functions when the factory control panel becomes worn or mechanically damaged.

Function And Application

The control panel operates the HVAC system’s user interface: it adjusts temperature settings, selects airflow distribution (dash/feet/windshield), engages or disengages the air conditioning compressor command, and operates recirculation. On many 207 models this is a mechanical/electrical assembly with rotary knobs, sliders or push-buttons that send signals to actuators and the climate control system.

How Replacement Works

Replacement is straightforward for someone with basic workshop tools. Typical steps: remove lower dash trim or center console surround to access the control module, disconnect the electrical connector(s), remove the fasteners or retaining clips, replace the unit and reconnect the harness. Refit trim panels and test all HVAC functions. Expected time: approximately 30–60 minutes depending on trim level and experience.

Installation Recommendations

Use plastic trim tools to avoid damaging dash panels. Before disconnecting any connectors, set the ignition off and follow vehicle manufacturer recommendations regarding electrical safety. After installation, verify all HVAC modes, recirculation, AC engagement and blower response across positions. If actuators or cables are faulty, replace them together with the control panel for full functionality.

Why This Part Usually Fails

Failures are most often caused by mechanical wear of switches, broken plastic levers or sliders, dirty/corroded contacts in potentiometers or connectors, and cracked mounting clips due to age. Repeated use and exposure to cabin dust and humidity accelerate wear. In some cases, problems with linked cables or vacuum/electric actuators may be misdiagnosed as control-panel faults.

Notes For Professionals

Part numbers are commonly used by technicians and customers when searching for replacements; include N102079B and 6451TK in searches to improve results. Where symptoms include partial function or intermittent operation, inspect connectors and the HVAC actuator cables before replacing the control panel.
