Technicians and DIY installers often look for the following reference numbers when sourcing this switch.

Technical Information

• Manufacturer: Stellantis (Citroën/Peugeot)
• Model: Peugeot 307; Peugeot 607
• Product Codes: 96296491ZL; 8904TW
• Additional Numbers: NFP (as marked)

Installation Recommendations

• Always follow manufacturer service instructions and safety procedures during removal and installation.
• Disconnect the negative battery terminal before starting work to avoid short circuits and to protect vehicle electronics.
• Remove the seat trim or center console bezel as required to access the switch. Use appropriate trim tools to avoid damaging panels.
• Unplug the electrical connector from the old switch and note connector orientation. Replace the switch and reconnect firmly.
• Test functionality before reassembling trim: verify all heat levels and indicator lights (if equipped) operate correctly.
• Reinstall trim pieces carefully and ensure clips and fasteners are secured to prevent rattles or loose panels.

Most Common Failure Causes

Seat heater switches typically fail due to mechanical wear of internal contacts from frequent use, ingress of moisture or dirt causing corrosion, or internal PCB/potentiometer faults leading to intermittent operation or complete loss of function. Overheating from a faulty seat heating element or poor electrical connections can also accelerate switch deterioration. Regular inspection and secure connector fitment help prolong service life.

Why Choose This Part

For workshops and experienced DIYers, replacing a faulty seat heater switch with a correct-fit unit restores driver comfort and avoids electrical faults that can affect seat heating circuits. Using the correct part number (e.g., 96296491ZL or 8904TW) reduces installation time and ensures compatibility with the vehicle’s original wiring and mounting points.
