Description
Left front window regulator mechanism for PEUGEOT 307 CC. Driver side.
This electric window regulator assembly is designed for the left (driver) front door of the Peugeot 307 CC (Coupe Cabriolet). It restores reliable window travel, smooth up/down movement and secure positioning. The unit is commonly searched by part numbers and original equipment codes, so compatibility is often checked by those references. It is suitable for professional workshops and DIY mechanics who need a direct-fit replacement for worn or failed regulators.
Application And Fitment
Fits Peugeot 307 CC (Coupe Cabriolet) left front door — Driver Side. Typical model years: early 2000s production of the 307 CC range. Always verify the part numbers listed below against the vehicle documentation or the label on the original part.
Function And Symptoms
The window regulator mechanism moves the glass up and down and maintains its position. Symptoms of a failing regulator include slow or jerky window movement, grinding or rattling noises inside the door, window falling down or not staying in position, and complete loss of movement while the motor may still operate. Replacing the regulator usually restores correct operation without the need to replace the whole door module.
Replacement Procedure (Overview)
- Disconnect the negative battery terminal to prevent accidental motor activation.
- Remove the interior door trim panel and any moisture barriers to access the regulator.
- Disconnect the electrical connector for the window motor and any door harness clips.
- Support the window glass (tape or suction cup) and detach the glass from the regulator.
- Unbolt and remove the faulty regulator assembly from the door shell.
- Install the new regulator, reattach the glass, reconnect electricals and test window operation before reassembling the door trim.
- Reinstall the door trim and reconnect the battery. Perform final checks for correct travel and alignment.
Recommended Installation
Installation is best performed with basic workshop tools and moderate mechanical experience. Use correct torque for fasteners and take care when handling the glass. Replace any deteriorated door clips or seals during reassembly to maintain water sealing. If the motor and regulator are separate and the motor shows signs of failure, consider replacing both components at once for long-term reliability. Always test the full travel and auto-reverse (if equipped) after installation.
Common Failure Causes
Regulators typically fail from wear of moving parts (cables, sliders, plastic drums), corrosion from moisture ingress, damaged guide channels, or stress from forcing the window when obstructed. Electric motor wear or electrical connector corrosion can also cause intermittent or complete failure. Regular use over many years and exposure to road moisture shorten service life.

Notes For Mechanics
Keep replacement fasteners and door clips on hand; door trim clips often break during removal. If the original regulator shows signs of water damage or heavy corrosion, inspect the door cavity for drainage issues. For professional fitment, align the glass at several points of travel to ensure it seals correctly at the upper stop and does not bind in the run channels.
