Description
Electric window regulator for the right front window for Citroën C4 B7 and DS4. The plastic slider is cracked (common on most cars), but solid and fully functional. Front passenger door.
Product Overview
This used electric window regulator / motor assembly is designed for the right front (passenger) door of Citroën C4 B7 (C4 II) and DS4 models. Supplied with OEM references 9802531780 and 9222GN, the unit drives the glass up and down via the regulator mechanism. The plastic slider shows a typical crack (a common wear item on these cars) but remains structurally sound and the unit operates correctly. Ideal for mechanics and DIY enthusiasts looking for a direct-fit replacement at a lower cost than new parts.

How It Is Replaced
Typical replacement steps for experienced mechanics or competent DIYers:
- Remove the door trim panel and detach any clips carefully to avoid damage.
- Disconnect the door wiring connector to the window motor and remove the moisture barrier.
- Support the glass (tape or wedge) and unbolt the regulator from the glass mounting points.
- Unbolt the regulator/motor assembly from the door shell and withdraw the unit through the access opening.
- Install the replacement assembly, secure all fasteners, reconnect the motor connector and test window operation before reassembly.
- Reinstall the moisture barrier and door card, ensuring all clips and screws are refitted.
Installation Recommendations
- Disconnect the vehicle battery before starting work to prevent accidental motor operation and reduce risk when handling door electronics.
- Use appropriate tool access and protect the interior trim and glass during removal/installation.
- Check regulator mounting bolts for correct torque and ensure the glass is properly seated in its clips to avoid binding.
- After fitting, operate the window through its full travel several times to confirm smooth movement and correct alignment.
Why This Part Fails Most Often
Common failure causes for front electric window regulators on these models:
- Plastic Slider Wear Or Breakage: The guide/slider is a plastic component that becomes brittle with age and may crack or deform—this is the issue noted on this unit but it remains functional.
- Cable Stretch Or Fraying: Regulators that use cables can suffer from fraying or detachment, causing jerky movement or complete failure.
- Motor Wear: Carbon brushes and commutator wear reduce motor torque over time, leading to slow or intermittent operation.
- Water Ingress And Corrosion: Moisture entering the door can corrode fasteners or electrical contacts, impairing operation.
- Mechanical Binding: Misaligned glass or worn guide channels increase load on the regulator and accelerate wear.
Signs You Need Replacement
- Slow or uneven window travel
- Grinding, clicking, or scraping noises during operation
- Window falls down or will not stay in position
- Intermittent operation or no response from the switch
