Part description

This left front window motor is designed for Peugeot 307 CC (up to 2004) and is suitable as a replacement if the original mechanism on the driver’s side fails. This is a used part from the Stellantis range (Citroën/Peugeot) with verified functionality – tested.

According to the documents, the part is designed with a folding mirror function and with window control via a handle. When replacing, the key is to stick to matching product numbers and designs so that the engine works properly with the car’s equipment.

Installation recommendations

Generally/typically for a window winder motor the exact procedure may vary depending on the specific door design and equipment (eg integration with winder mechanics, controls and wiring). Below is a safe practical procedure used in practice when replacing this type of part.

1) Before assembly

• Compare the old and the new part: same numbers 9651735280 / 9221P8, same design (according to the documents of the folding mirror function, window control via the handle), same connectors and mounting.
• Check the condition of the connector and wiring in the door (oxidation, pulled pins, insulation damage).
• Check the mechanical part of the puller (cables/drives) – stuttering often overloads the motor.

2) Necessary tools and materials

• Basic set of screwdrivers and bits (according to the screws used in the door)
• Plastic crowbar for upholstery
• Gloves, contact cleaner (as needed)
• Contraction tapes / insulating tape for safe routing of cabling (as needed)

3) Step-by-step assembly procedure

1. Turn off the ignition and disconnect the battery to be safe (recommended practice for door wiring).
2. Remove the door trim/upholstery and carefully disconnect the controls’ electrical connectors.
3. Remove the protective film/cover (if present) so that it seals properly again.
4. Secure the glass against falling (typically with tape or a suitable support) so that it does not slide down when the mechanism is disengaged.
5. Disconnect the window download engine connector.
6. Unfasten the motor and, if necessary, parts of the puller mechanism according to the design (note the position and routing of the cabling).
7. Remove the original motor and compare the mounting and fitment with the replacement piece again.
8. Mount the 9651735280 motor back in place and fix it to the original points.
9. Connect the electrical connector and check that it clicks and there is no play.
10. Perform the first functional test (briefly, with the glass secured): the up/down movement must be smooth and without unusual noises.
11. Put back the protective foil/cover and make sure it is tight so that water does not get into the door for the wiring.
12. Refit the door panel/trim and all removed elements.

• 4) Post-assembly checks and test drive/function verification

  • Repeatedly verify the operation of the window in its entire range (no stuttering, no skipping).
  • Check that the wiring is not rubbing or pinched under the upholstery.
  • If the car has the relevant equipment according to the documents, check the function of the related elements (e.g. folding mirror).

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

  • Design interchange (other connectors/features): always check part numbers and design match before assembly.
  • Unsecured glass: the glass can fall and be damaged – always secure it before disconnecting the mechanism.
  • Ignoring stiffened puller mechanics: if the drives/cables rub, the motor is overloaded and may go away again.

  Reasons why the part is damaged

  • Carbon and commutator wear in the electric motor due to age and frequent use.
  • Increased resistance of the puller mechanics (stuttering of drives, damaged cables), which overloads the motor.
  • Moisture in the door and subsequent oxidation of the connectors or internal parts of the engine.
  • Damage to the wiring in the door bushing (broken wires, breaks) leading to irregular operation and overloading.
  • Mechanical damage during unprofessional disassembly/assembly (torn attachment, damaged connector).
