Description
Electric window regulator for the left front window for Citroën C4 B7 and DS4. The plastic slider is cracked (common on most cars), but solid and fully functional. Driver Door.
Product Overview
This electric window regulator is designed for the left front (driver) door of Citroën C4 B7 and DS4 models. It includes the motor-driven mechanism and mounting points required to raise and lower the glass. The part is a used component with a cracked plastic slider—this cosmetic damage is common on many vehicles but does not affect the structural integrity or operation of the regulator. Ideal for mechanics and experienced DIYers looking for a cost-effective replacement that restores reliable window operation.
Key Benefits
- Direct fit for Citroën C4 B7 and DS4 driver door applications.
- Restores smooth electric window operation without the higher cost of a new OEM assembly.
- Includes original motor and gearset; tested for movement and mechanical engagement during removal (note: not a claim of manufacturer testing).
- Common replacement part number(s) visible for fast search and ordering: 9802531980, 9221GR.
How It Works
The regulator converts rotary motion from the electric motor into vertical movement of the window glass via cables or a scissor/mechanism and a sliding carrier (plastic slider). The slider guides the glass along the track; if the slider weakens or the cables/motor wear, the window can become noisy, slow, or fail to move completely.
How To Replace
Replacement requires basic door trim removal and electrical disconnection. Typical replacement steps:
- Disconnect the negative battery terminal to avoid accidental operation of the window motor and for safety.
- Remove interior door trim, handle bezels, and any clips securing the panel.
- Peel back the moisture barrier to access the regulator and motor assembly.
- Support the glass in the up position (tape or suction cups) and unbolt the glass from the regulator carrier.
- Disconnect the electrical connector to the motor and remove the mounting bolts securing the regulator to the door shell.
- Withdraw the regulator assembly through the service openings and transfer any required brackets or clips to the replacement unit if needed.
- Install new regulator, reconnect motor connector, reattach glass, test window operation for smooth travel and correct alignment before reassembling the door trim.
Installation Recommendation
Installation is recommended to be carried out by a trained technician or an experienced DIYer with the correct tools. Use appropriate fastener torque values where specified by the vehicle manufacturer and verify smooth, full travel of the glass before final assembly. Always disconnect the battery before starting work on door electrics. If the window track is corroded or the glass alignment is off, address those issues to prevent premature wear on the new regulator.
Most Common Cause Of Failure
Window regulators commonly fail due to one or more of the following: deterioration or breakage of the plastic slider, frayed or snapped cable, worn motor brushes, water ingress causing corrosion, or misalignment that increases mechanical load. The plastic slider on this unit is cracked—a frequent wear item—but the mechanism remains structurally sound and operational.
Typical Lifespan
Service life depends on usage and environment. Regularly used windows in vehicles 8–15 years old are the most common candidates for regulator replacement. Exposure to moisture, road salt, and frequent use accelerates wear.

Notes For Mechanics And DIYers
Keep a clean working area when handling the door glass and regulator. If reusing glass mounting bolts or clips, inspect them for deformation and replace if necessary. After installation, cycle the window several times to ensure smooth operation and proper seating of the glass. Address any door seal issues or track obstructions to extend regulator life.
