Description
Electric window regulator mechanism for the left rear window for Citroën C4 Picasso and Grand Picasso
Rear door, driver side
Product Overview
High-quality electric window regulator mechanism designed as a direct-fit replacement for the left rear (behind the driver) door of Citroën C4 Picasso and Grand Picasso models. This unit restores reliable up-and-down movement of the rear glass, helping to eliminate rattles, slow operation or complete loss of function caused by worn cables, broken guides or motor faults. Frequently searched and ordered by product codes 9223E0 and 9682632180.
Key Benefits
- Direct OEM-fit design for simple replacement without major modifications.
- Complete mechanism assembled for quick installation: regulator assembly with mounting points and motor interface.
- Improves sealing and smooth travel of the window glass, reducing wind noise and water ingress into the door.
- Saves workshop time with familiar mounting points for technicians and experienced DIYers.
How It Works
The regulator converts the electric motor’s rotation into linear motion that raises and lowers the window glass. Typical designs use a cable-and-pulley or scissor mechanism guided by plastic or metal runners. Over time, moving parts and plastic slides wear, cables can fray, and water or dirt can accelerate deterioration — leading to slow, noisy or intermittent operation.
Installation Recommendations
Professional fitment recommended for technicians and experienced DIY enthusiasts. Typical replacement steps:
- Prepare: Park the vehicle on level ground and ensure ignition is off. Disconnect the negative battery terminal before starting work to avoid short circuits and accidental window movement.
- Remove Door Trim: Carefully remove the inner door panel and any trim clips to access the regulator. Protect trim clips and fasteners for re-use.
- Support Glass: Secure the window glass in the fully up position with tape or a support tool, or remove the glass if required by the procedure.
- Disconnect: Unplug the electrical connector to the window motor and undo regulator mounting bolts. Note fastener locations for correct reassembly.
- Replace: Remove the old regulator assembly and fit the new unit. Reattach glass to the regulator, torque mounting bolts to manufacturer recommendations, and reconnect the motor plug.
- Test: Reconnect the battery, cycle the window through full travel to check correct operation and alignment before refitting the door trim.
- Final Checks: Lubricate sliding tracks lightly with appropriate grease, ensure moisture barrier is resealed, and verify all clips and screws are secured.
Why This Part Commonly Fails
- Wear From Use: Frequent operation leads to worn cables, stretched or frayed lines, and degraded plastic sliders or guides.
- Water And Dirt Ingress: Moisture or grime inside the door can corrode metal parts and deteriorate plastic runners, causing binding or breakage.
- Motor Load And Overheating: A weak or partially seized motor puts extra load on the regulator and accelerates mechanical failure.
- Impact Or Misalignment: Door impacts or misaligned glass can overload the mechanism and cause premature damage to gears or cables.

Compatibility And Notes
This unit is intended for the left rear door (behind the driver) on Citroën C4 Picasso and Grand Picasso models. Always confirm the product code matches the vehicle’s existing part number before ordering. When replacing, inspect the door wiring harness and connectors for corrosion and repair as necessary to prevent future electrical faults.
Professional Tip
When fitting a new regulator, check the window run channels and rubber seals. Worn seals increase friction and shorten the life of the new regulator. If the motor is suspect but the regulator is intact, test motor operation separately — replacing the regulator assembly is often the most cost-effective long-term solution.
