Description
Electric window regulator for the right rear window for CITROËN C4 B7. The plastic slider is cracked (common on most cars), but solid and fully functional. Rear right door (behind the front passenger).
This used electric window regulator is a practical replacement part for mechanics and DIY enthusiasts working on Citroën C4 B7 vehicles. Designed to restore smooth, reliable operation of the right rear window, this unit retains full functionality despite a cracked plastic slider—an issue frequently seen on many cars of this age. If your rear right window moves slowly, jams, or drops unexpectedly, replacing the regulator often solves the problem and prevents further damage to the glass or door internals.

Installation Recommendations
- Preparation: Gather basic tools (trim tools, Torx/screwdrivers, socket set) and work on a stable surface. Protect the glass with tape or a helper supporting the window.
- Removal: Remove the door trim panel carefully to access the regulator and motor. Disconnect the electrical connector and detach any water shield. Support the glass before unbolting the regulator mounts.
- Replacement: Unbolt the old regulator and motor assembly, transfer any required clips or guides if necessary, and fit the new unit. Align the window glass in the regulator clamps and tighten bolts to manufacturer torque where available.
- Testing: Reconnect the electrical connector and operate the window through its full travel to confirm smooth movement and correct alignment before reassembling the door trim.
- Safety Tip: Work methodically and keep fasteners organized. If unsure about handling the glass or electrical connector, seek a professional workshop.
Why This Part Most Often Fails
- Plastic Slider Wear: The plastic slider/guide commonly develops cracks or wear over time, causing uneven movement or play in the mechanism.
- Cable Or Gear Wear: Cables, pulleys or gear teeth inside the regulator can fray or strip, leading to jamming or loss of motion.
- Water Ingress And Corrosion: Moisture inside the door can accelerate corrosion of metal parts and cause premature motor or mechanism failure.
- Motor Wear: Electric motor brushes and commutator wear with use, reducing torque and leading to slow or intermittent operation.
- Misalignment Or Impact Damage: Door impacts or improper previous repairs can bend components or misalign the regulator, causing binding.
Symptoms Of A Faulty Regulator
- Window Moves Slowly Or Sticks
- Unusual Grinding Or Rattling Noises During Operation
- Window Drops Partially Or Won’t Stay Up
- Window Won’t Move Or Responds Intermittently
Replacing the regulator with a unit that retains the original mounting points and electrical connector is the most reliable way to restore normal window operation. Using the part number 9820885080 / 9224H4 will increase the likelihood of correct fitment for Citroën C4 B7 applications.
