Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 407 (Passenger Side)
- Product Codes: 96457004XT, 8149VC
- Other Numbers: KNND (Color Code: Alcyon Blue)
Features And Function
The mirror provides electric adjustment for precise viewing angle, an electric folding mechanism to protect the mirror when parked, a heated glass element to remove ice and fog, and a temperature sensor used by the vehicle climate/monitoring systems. All electrical functions are supplied via the vehicle wiring harness and controlled from the door switches and vehicle body modules.
Installation Recommendations
- Tools Required: Torx or metric sockets for door mirror bolts, trim removal tools, small flat screwdriver, electrical connector release tool.
- Procedure Overview: Remove interior door trim or triangular trim cover, disconnect the mirror electrical connector, remove mirror mounting bolts, remove old mirror assembly and fit the new unit. Reconnect the wiring, test adjustment, heating and folding functions before reassembling the trim.
- Precautions: Disconnect the negative battery terminal before working on electrical components to avoid short circuits. Avoid forcing plastic clips—use proper trim tools to prevent damage. Ensure connectors are fully engaged and routing does not pinch wires when reassembling.
- Testing: Verify mirror adjustment in all directions, confirm heating element operation (may be checked by hand after a short activation period or via diagnostic functions), and test electric folding both from switch and automatic folding if equipped.
Why This Part Most Often Fails
- Impact Damage: Collisions or knocks are the most common cause—broken housing, cracked glass or damaged folding mechanism.
- Wear And Moisture Ingress: Water entry at the mirror base or connector can corrode contacts, causing intermittent or permanent loss of motor, folding or heating functions.
- Mechanical Fatigue: Repeated folding cycles can wear the actuator gears or pivot bushings, eventually causing noisy operation or failure to fold.
- Electrical Faults: Wiring harness damage in the door hinge area or failing connectors can interrupt power to motors or heating elements.
Practical Tips For Garages And DIYers
- Always compare product codes (96457004XT, 8149VC) and color code (KNND) with the vehicle part to ensure match at the time of replacement.
- If clips or screws are damaged on removal, replace them to guarantee secure reinstallation and to avoid wind noise or water ingress.
- When troubleshooting, check for power and ground at the mirror connector first, then operate the mirror functions while monitoring for mechanical binding or unusual noises.
