Part description

The used window lowering mechanism is intended for the Peugeot 307 and corresponds to the design for the right rear window. It is a part sought after in particular by product numbers 4005854V and 9224A6, which facilitates correct identification when replacing the original damaged mechanism.

This auto part is suitable for repairing a non-functioning or stuttering window winder when the original mechanism shows wear, erratic operation or complete non-functionality. It is a practical choice for auto mechanics and DIYers when restoring the full function of the window control without having to look for a new original part.

Installation recommendations

For this part, the documents contain basic information about the destination for the right rear window of the Peugeot 307 5 door. The exact disassembly and assembly steps may vary depending on the specific car model, so below is a generally typical procedure for replacing the window winder mechanism.

1) Before assembly

• Check that the new and original part match in shape, fit, routing and connectors if part of the mechanism.
• Compare the product numbers 4005854V and 9224A6 with the old part if they are legible.
• Check the condition of the guide parts, cables and attachment points of the used part.
• Before installation, also check the condition of the glass, guide rails and the inside of the door so that the new mechanism does not work in a damaged or dirty area.

2) Necessary tools and materials

• Common set of screwdrivers and sockets
• Plastic pry bar for panel removal
• Pliers
• Detergent for removing dirt
• Cloth or towels
• Alternatively, a suitable agent for light lubrication of moving parts, if the condition of the mechanism requires it

3) Step-by-step assembly procedure

1. Disconnect the battery, especially if you will be handling the electrical connectors in the doors.
2. Dismantle the inner door trim carefully so as not to damage the fasteners or cover parts.
3. Remove the protective layer or access cover if present in the door.
4. Secure the glass against spontaneous movement so that it does not fall when disassembling the mechanism.
5. Disconnect the electrical connection of the mechanism if it is part of the assembly.
6. Unfasten the old mechanism and carefully remove it from the door area.
7. Compare the removed part with the replacement part, especially the attachment points, guides and overall design.
8. Clean the door area, remove dirt and check for damage to the guide or support elements.
9. Place the replacement mechanism in place and seat it into the correct position without force.
10. Sequentially fasten all mounting points and connect the electrical connector if present.
11. Carefully connect the mechanism to the glass and check that the glass sits correctly in the guide.
12. Before fully folding the door, perform a control run of the mechanism and observe the smoothness of the movement.
13. After verifying the function, replace the protective cover and install the door trim.
• 4) Post-assembly checks and test drive/function verification
  • Verify that the window moves up and down smoothly without rubbing, skipping or unusual noises.
  • Check the correct seating of the glass in the upper position.
  • Check that the glass does not tilt during movement and remains correctly guided.
  • After folding the door, retest the control function and check that nothing inside the door is vibrating or loose.

  5) The most common assembly mistakes + how to avoid them

  • Incorrect part comparison before installation – always compare the old and new mechanism before fitting it into the door.
  • Door panel damage – use suitable plastic tools and remove the panel carefully.
  • Unsecured glass during work – always secure the glass securely before disassembling the mechanism.
  • Mounting in a dirty area – dirt in the line can cause heavy operation and shorten the life of the part.
  • Forced seating of the mechanism – if the part does not fit naturally, recheck the orientation and fit of the fit.

  Reasons why the part is damaged

  • normal mechanical wear during long-term use,
  • damage to cables or guiding parts of the mechanism,
  • increased resistance to glass movement in dirty or worn guides,
  • strain with a frozen or stuttering window,
  • intrusion of moisture and dirt into the door area,
  • secondary damage after unprofessional disassembly or assembly.
