This motor gearbox drives the left front window regulator on Peugeot 308 (T7) driver’s doors. Ideal for professional workshops and experienced DIY mechanics, this unit is referenced under several OE numbers (9657247680, 9675467480, 0130822742, 9221CX) and is commonly searched by part number when replacing a faulty window motor. Robust and compact, the assembly restores smooth, reliable up-and-down operation of the driver’s window and eliminates slow, noisy or stuck windows caused by a worn motor or gearset.

Technical Information

• Manufacturer: Stellantis (Citroën/Peugeot)
• Model: Peugeot 308 (T7) — Left Front Driver’S Door
• Product Codes: 9657247680, 9675467480, 0130822742
• Other Numbers: 9221CX, 9221.CX, 130822368

Function And Typical Symptoms

The unit is an electric motor with an integrated gear reduction that powers the window regulator mechanism. Its function is to convert electrical input from the window switch into rotational torque to move the glass smoothly along the guide tracks. Common symptoms of a failing motor include:

• Intermittent or no movement from the driver’s window switch.
• Slow or labored window travel compared with other doors.
• Grinding, clicking, or whining noises from inside the door when operating the window.
• Window becomes stuck in one position or falls down due to regulator slipping.

Most Common Causes Of Failure

• Wear Of Internal Brushes Or Commutator: Progressive loss of electrical contact reduces torque and causes intermittent operation.
• Gear Wear Or Stripped Teeth: Mechanical wear in the plastic/metal gearset leads to slipping or grinding.
• Water Ingress And Corrosion: Moisture entering the door cavity can corrode electrical connections and motor internals.
• Regulator Binding Or Misalignment: Excessive load from a damaged regulator or seized window guides overloads the motor.
• Electrical Issues: Corroded connectors, broken wires, or faulty switches can mimic motor failure.

Installation Recommendations

Recommended For Experienced Mechanics And Confident DIYers. Typical Replacement Steps:

1. Disconnect The Battery Before Starting To Prevent Short Circuits And Avoid Damaging The Electrical System.
2. Remove The Door Trim Panel And Vapor Barrier Carefully To Access The Regulator Assembly.
3. Lower The Window To A Position Where The Glass Can Be Secured, Then Unbolt The Glass From The Regulator And Support It Safely.
4. Unplug The Electrical Connector From The Motor, Unbolt The Motor From The Regulator, And Remove The Unit.
5. Fit The Replacement Motor, Reconnect The Electrical Plug, Reattach The Glass, And Test Window Function Before Reassembling The Door Panel.
6. Check For Smooth Operation Through Full Travel; Adjust Regulator Alignment If Necessary.

No Programming Is Typically Required: In most cases This Motor-Regear Is Plug-And-Play. However, Always Follow The Vehicle Manufacturer’S Procedure And Re-Test All Window Functions After Installation.

Why Professional Fitment Can Be Beneficial

Correct Diagnosis Is Crucial: Symptoms Can Be Caused By Regulator Mechanism, Electrical Faults, Or The Motor Itself. Professional Workshops Will Ensure The Regulator Slides And Guides Are In Good Condition And Replace Or Lubricate Them If Needed, Preventing Premature Failure Of The New Motor.
