Description
Window regulator mechanism for the left rear door for PEUGEOT 308 T7. Motor can be purchased separately. Rear door on the driver’s side.
Product Description
This left rear window regulator mechanism is designed for the PEUGEOT 308 (T7) and replaces the internal assembly that guides and raises/lowers the window glass. Sold as the mechanical regulator without the electric motor (motor available separately), it is a direct-fit aftermarket component referenced by product codes 9680979080 and 9223E5. Ideal for professional workshops and experienced DIYers, the unit restores smooth window movement, eliminates rattles and prevents glass misalignment when correctly installed.
Technical Information
- Manufacturer: Stellantis / Peugeot
- Model: Peugeot 308 (T7)
- Product Codes: 9680979080, 9223E5
- Other Numbers: NFP
- Position: Left Rear (Driver’s Side)
Function And Fitment
The regulator converts rotational motion from the window motor (if fitted) into the vertical travel of the glass via cables, guides or gears, depending on the specific regulator design. It secures the glass inside the door and keeps movement aligned and stable. This part fits the left rear door on Peugeot 308 T7 bodies and is intended to be a replacement for worn or damaged factory regulators.
Installation Recommendations
- Always work on a level surface and protect the vehicle interior and glass.
- Disconnect the battery before beginning work to avoid accidental activation of electrical components.
- Remove the door trim and moisture barrier carefully to access the regulator. Keep clips and fasteners organized for reassembly.
- Support the window glass (tape to the door frame or use a helper) before disconnecting the regulator from the glass to prevent dropping and breakage.
- Disconnect any electrical connectors (if motor or switches are present) and unbolt the regulator from the door shell.
- Fit the new regulator in reverse order: secure mounting points, attach glass, reconnect motor or wiring, and test full travel of the window before refitting trim.
- Check and lubricate sliding points and bolts where appropriate. Replace any corroded or damaged fasteners.
Most Common Failure Causes
- Wear Of Plastic Rollers Or Guides: Repeated use degrades plastic components that guide the glass, causing noise, binding or loss of alignment.
- Cable Fraying Or Breakage: Cable-type regulators can suffer from frayed or snapped cables that prevent movement.
- Gear Wear Or Stripping: Mechanical gears in some regulators can wear out, especially if contaminated with dirt or moisture.
- Corrosion And Water Ingress: Moisture inside the door accelerates corrosion of metal parts and can seize moving elements.
- Motor Failure (If Applicable): While this listing is for the mechanism, an attached motor can fail and is often the cause of a non-functioning window—motors are available separately.
Practical Tips For Workshop And DIY
Inspect the glass mounting points and the door inner surface for rust before fitting the new regulator. If glass runs rough after installation, verify that the glass is seated squarely in the regulator clamps and that the channels are clean. Test the full travel several times to ensure smooth operation and to allow any seating of components before reassembling the door trim.
