This replacement passenger-side seat belt buckle bracket (often searched under part numbers 8975AV or 8973QY) is designed for Citroën C8 and Peugeot 807 models. The unit includes the buckle mounting and a latch switch for the seat-belt alarm/occupant-detection circuit. Built to OEM fitment standards, it restores secure latching, reliable buckle sensing and correct alarm/warning lamp behaviour after failure or damage.

Technical Information

Function and Benefits

The buckle bracket secures the seat-belt latch and houses the microswitch that tells the vehicle whether the belt is fastened. A properly working unit ensures the seat-belt warning alarm and related safety logic operate correctly. Replacing a faulty buckle bracket restores safe restraint operation, prevents false alarm warnings, and ensures the seat-belt is held positively under load.

Installation Recommendations

• Always disconnect the vehicle battery before starting work to avoid short circuits and protect vehicle electronics.
• Remove the appropriate trim panels and seat fixings to gain access to the buckle mounting. Use proper trim tools to avoid damaging interior panels.
• Unbolt the old bracket, carefully disconnect the electrical connector for the buckle switch, and remove the unit.
• Fit the new bracket in the correct position, connect the electrical connector securely, and tighten mounting bolts to the manufacturer’s torque specification.
• Reinstall trim and seat components, reconnect the battery, and verify that the seat-belt buckle latches smoothly and the seat-belt warning/alarm operates as intended.
• Avoid applying lubricants to the sensor contacts. If connectors show corrosion, clean or replace as needed to ensure reliable operation.
• If in doubt about correct torque values or electrical checks, follow manufacturer repair procedures or consult service documentation.

Why This Part Most Commonly Fails

• Mechanical Wear: Repeated latching/unlatching and debris ingress can wear the latch mechanism or switch over time.
• Contamination and Corrosion: Dirt, liquids or corrosion can impair the microswitch or connectors, causing intermittent or permanent faults.
• Impact Damage: Seat-belt mounts and buckles are vulnerable in collisions; visible deformation or bent brackets require replacement.
• Electrical Faults: Broken wiring, damaged connectors or failed microswitches can prevent correct alarm/warning signals.
• Aging: Plastic components, clips and wiring harnesses degrade with age, particularly in high-use or high-humidity environments.

Practical Tips for Mechanics and DIYers

• Search by product codes 8975AV or 8973QY for fast identification and ordering.
• Inspect surrounding seat-belt components (anchor bolts, webbing, retractor) when replacing the buckle bracket to ensure overall system integrity.
• After installation, perform a functional check: buckle/unbuckle several times, confirm alarm/warning light behavior, and visually inspect for secure mounting.
