Description
Left front window regulator motor for Peugeot 307 vehicles. Without folding mirror function. Not suitable for CC Cabriolet.
This left front window regulator motor is intended for professional workshops and DIY enthusiasts who maintain Peugeot 307 cars. It restores reliable up-and-down movement of the driver-side window and is often searched by its product codes 9634457580 and 9221N5. The unit is suitable for many Peugeot 307 applications (see technical information below) and is a direct replacement for the standard electric window drive used on these models.
Technical Information

Function
The motor provides the electrical drive to the window regulator mechanism, converting electrical energy into rotational motion to raise and lower the left front window. It works together with the regulator (gear, cable or scissor mechanism depending on the version) and the vehicle’s window switch to control window movement.
Installation Recommendations
Recommended steps for replacement: disconnect the negative battery terminal before starting work; remove the inner door trim and carefully peel back the moisture membrane; support the glass (use tape or a support tool) so it cannot fall; disconnect the electrical connector to the motor; unbolt the motor or motor/regulator assembly and remove it from the door; install the new motor, reconnect the electrical plug and temporarily reconnect the battery to test window travel and alignment before reassembling the door. Lubricate guide rails lightly and check that the glass runs freely in its channels. Refit the moisture barrier and door trim only after correct operation is confirmed.
Common Failure Causes
- Water ingress and corrosion inside the motor or on electrical contacts.
- Wear of internal brushes or commutator, leading to reduced torque or failure to start.
- Stripped or damaged plastic gears inside the motor assembly.
- Regulator mechanism problems (binding rails, broken cables or worn sliders) that overload the motor.
- Electrical issues such as damaged wiring, poor connectors or blown fuses affecting power delivery.
Practical Notes
Failure often occurs after many years of use or when water and dirt enter the door cavity. If the window moves slowly or intermittently, check tracks and regulator condition in addition to the motor. This part is not suitable for the CC Cabriolet version of the 307—verify the body type before ordering. Many customers search by the part numbers 9634457580 or 9221N5 to find the correct replacement.
