Description
Electric window regulator mechanism for the left rear window for Citroën C4 Picasso and Grand Picasso. Fits the rear left (driver’s side).
Product Overview
This replacement electric window regulator is designed for the left rear door of Citroën C4 Picasso and Grand Picasso models. It includes the mechanical regulator assembly that guides the glass and the cable/slider system driven by the window motor (motor may be integrated or separate depending on version). Ideal for professional workshops and experienced DIYers searching by part number (9682632180 / 9223E0).
Why This Part Fails
- Wear Of Moving Parts: Plastic guides, sliders or cable assemblies wear over time and can break or stretch, causing the window to jam or drop.
- Corrosion And Water Ingress: Moisture inside the door leads to rust on tracks and fasteners or causes electrical connector problems.
- Motor Or Gear Damage: Excessive load from a jammed glass or failed bearings can burn the motor or strip internal gears.
- Fastener And Rivet Failure: Rivets or mounting points can shear, causing misalignment or detachment of the regulator.
Typical Lifetime And Symptoms
Expected service life varies with use and environment; 8–12 years is common under normal conditions. Symptoms of a failing regulator include slow or noisy movement, the window stopping mid-travel, excessive play in the glass, or the glass falling into the door. If you hear grinding, skipping or intermittent motor operation, inspect the regulator and motor assembly.
Replacement Procedure (Overview)
Recommended for trained technicians or experienced DIYers. Typical steps:
- Lower the window (if possible) to access mounting points, then remove interior door trim and moisture barrier carefully.
- Disconnect the electrical connector to the window motor. Before working, disconnect the battery to avoid short circuits and accidental window movement.
- Support the glass in position (suction cups or tape) and remove bolts/rivets securing the regulator to the door and glass.
- Remove the old regulator assembly and compare mounting points and connectors with the new unit.
- Install the new regulator, attach the glass, reconnect the motor connector and check operation before reassembling the door trim.
- Adjust window alignment if needed and verify smooth operation through full travel. Refit all trim and ensure door seal integrity.
Installation Recommendations
- Always Disconnect Battery Before Work: Reduce risk of electric short or accidental motor activation.
- Inspect Door Drainage And Seals: Clear drainage holes and verify moisture barrier condition to prevent future corrosion.
- Use Correct Fasteners: Replace rivets or bolts with OEM-equivalent hardware and torque to manufacturer values.
- Test Before Final Assembly: Verify correct motor direction, full travel and absence of binding before refitting the trim.
- Lubrication: Apply appropriate lubricant to guide rails and sliders (use non-greasy products recommended for window mechanisms) to prolong life.

Compatibility And Notes
This regulator is specified for the left rear door (rear left, passenger/driver side depending on market). Confirm the part numbers printed on the old regulator match the numbers above when possible. The unit’s connector shape and mounting points should match the original; visual comparison is recommended during replacement.
Who Should Install
Recommended for professional technicians and skilled DIYers comfortable with door trim removal and electrical connectors. If uncertain about procedure or alignment, seek assistance from a workshop to avoid damage to the glass or door interior.
