Citroën C3 right front window retractor mechanism 400618 9222AP

Description

CITROEN C3 first series right front window retracting mechanism with sequential travel function
Passenger door

Part description

This right front window winder is for the Citroën C3 (first series) and is equipped with a sequential travel function. It is a part for the passenger’s door – it typically solves situations where the window cannot be operated smoothly, stutters, falls into the door or does not respond correctly to automatic/sequential control.

When choosing used window winders, the most important thing is to match the design and product codes (they are often searched for by the part number). This piece is suitable as a quick and economical replacement when repairing the window mechanism without unnecessary compromises.

Installation recommendations

Generally/typically for replacing the window mechanism (exact steps may vary depending on the specific door design and vehicle equipment):

1) Before assembly

• Compare the new and original part: codes 400618 / 9222AP, shape and attachment of the mechanism, type and routing of cables/drives.
• Check the mechanism for mechanical damage (bent parts, cracks, excessive play, stuttering).
• If a take-up drum/cable is included in the assembly, check that the cable is not frayed and properly routed.

2) Necessary tools and materials

• A set of common hand tools (screwdrivers, ratchet and extensions according to the used connecting material)
• Plastic pry bar for removing the upholstery (because of the clips)
• Protective gloves, possibly tape to secure the glass
• Cleaning agent for degreasing and rags (for cleaning contact surfaces/guides)

3) Step-by-step assembly procedure

1. Turn off the ignition and disconnect the battery to be safe (especially if you will be disconnecting the electrical connectors in the doors).
2. Dismantle the inner door panel and carefully release the cover film/membrane (if present) so that it can be resealed well afterwards.
3. Secure the glass against falling (typically with tape to the door frame) and prepare access to the glass attachment on the mechanism travel.
4. Release the glass attachment from the mechanism and secure the glass in the upper position.
5. Disconnect the relevant connectors if they are part of the assembly (according to the design).
6. Unscrew/unlock the fixing points of the puller mechanism in the door.
7. Remove the old mechanism from the door taking care not to damage the wiring, wiring or edges of the door.
8. Clean the space in the door and check the condition of the glass guides/channels (dirt often causes overloading of the mechanism).
9. Mount the new mechanism in the original attachment points and seat it without tension.
10. Attach the glass back to the mechanism travel and check for proper seating (so the glass is not crooked).
11. Before completing the door panel, perform a functional test of the window control and verify smooth operation in the entire track.
12. Put back the membrane/foil (important due to humidity), fit the upholstery and all covers/controls.
• 4) Post-assembly checks and test drive/function verification
  • Verify that the window goes up/down smoothly without stuttering or unusual noises.
  • Try sequential coasting (automatic coasting) – if it is part of the equipment and was working before the replacement.
  • Check the tightness and correct fit of the door film and filling (prevention of leakage into the interior).

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

  • Unsecured glass → there is a risk of the glass falling and damaging it; always secure the glass before loosening the fastening.
  • Bad seating of the glass in the drive → the window crosses and overloads the mechanism; after assembly, perform a test run several times.
  • Damaged/poorly glued membrane → leakage into doors and interior; return the membrane carefully and tightly.
  • Ignoring dirty guides → increased resistance and faster wear; clean the area before assembly.

  Reasons why the part is damaged

  • Wear of cables and winding mechanism (shaking, skipping, cracking).
  • Clogged or dry glass lines → increased resistance and overload of the puller.
  • Frequent use (typically for front windows) and gradual fatigue of the material.
  • Moisture and corrosion in the doors, which impair operation and accelerate the degradation of mechanical parts.
  • Incorrect assembly (crooked seating, mechanism tension, badly routed cable) which leads to rapid damage.
