Description
Right rear window regulator mechanism for Peugeot 307 vehicles
Electric window motor
Passenger side
Product Overview
This electric right rear window regulator and motor is designed for Peugeot 307 models and restores smooth, reliable operation of the passenger-side rear window. Ideal for professional workshops and experienced DIY mechanics, the unit replaces worn or failed regulators that cause slow movement, noisy operation, or a window that will not stay in position. Commonly searched by the part code 9224A4.
Key Benefits
- Direct Fit For Peugeot 307 Models — Designed to match factory mounting points and connectors where applicable.
- Complete Electric Drive — Includes the motorised mechanism for controlled up/down movement.
- Durable Construction — Components engineered to withstand regular use and exposure inside the door cavity.
- Easy Identification — Frequently referenced by code 9224A4 for fast lookup in parts catalogs.
How It Works
The window regulator converts the motor’s rotational force into linear motion to raise and lower the glass. The assembly typically uses a cable or scissor mechanism combined with guide rails and rollers to ensure smooth travel. The motor receives power through the door wiring and is controlled by the window switch and vehicle body control modules.
Recommended Replacement Procedure
- Disconnect Vehicle Battery Before Starting Work To Prevent Short Circuits And Avoid Unintended Window Operation.
- Remove Interior Door Trim And Any Moisture Barriers To Access The Regulator And Motor.
- Support The Glass Securely (Tape Or Wedge) Before Removing Regulator Fasteners.
- Disconnect Electrical Connector And Unbolt The Regulator From The Door Shell.
- Install The New Regulator, Reattach Glass To The Mechanism, And Test Operation Before Reassembling The Door Panel.
- Verify Smooth Travel And Correct Seating Of The Glass. Adjust Guide Positions If Necessary.

Installation Recommendations
Use proper trim removal tools to avoid damaging door panel clips. When refitting, lubricate guide rails and moving points with a suitable high-temperature grease to reduce wear and noise. Check door wiring and connectors for corrosion before reconnecting. Test the regulator through several full cycles with the door panel removed to ensure there is no binding and that the motor current draw is within expected range.
Why This Part Fails Most Often
- Motor Wear: Brushes and commutator wear over time, reducing torque and causing intermittent operation.
- Cable Or Pulley Failure: Frayed cables, broken plastic pulleys or snapped guides lead to loss of movement or dropped glass.
- Corrosion And Water Ingress: Moisture entering the door can corrode sliding tracks, fasteners, and electrical connectors.
- Mechanical Fatigue: Repeated stress on plastic components and rollers causes cracking or detachment.
- Obstruction Or Misalignment: Debris in the window channel or misaligned guides increases load on the motor and shortens service life.
Practical Tips For Diagnostics
- Check The Window Fuse And Switch Operation Before Replacing The Regulator.
- Listen For Motor Noise: A grinding or whining motor with no movement usually indicates a failed regulator or stripped gears.
- Measure Voltage At The Connector While Operating The Switch To Confirm Power Delivery.
- Inspect Guide Channels For Damage Or Debris That Could Be Causing Excessive Load.
