Replacement Procedure (General Guide)

Intended for experienced DIYers and professional technicians. Typical steps:

• Disconnect battery before starting work to avoid short circuits and accidental motor operation.
• Remove the door trim panel by releasing fixings and clips (armrest screws, door handle fasteners), then detach any electrical connectors for switches and speakers.
• Peel back the water/vapour barrier carefully to access the regulator area.
• Support the glass (use suction cups or tape) and, if necessary, move the window to the position where the glass can be unbolted from the regulator arms.
• Disconnect the motor electrical connector and remove the bolts securing the regulator and motor assembly to the door shell.
• Extract the old regulator and fit the new unit in reverse order. Reattach the glass to the regulator, reconnect the motor, and test the window operation before reassembling the door trim.

Estimated time: 0.5–1.5 hours depending on experience and access to correct tools.

Mounting Recommendations

• Always disconnect the negative battery terminal before starting to avoid electrical damage.
• Use correct trim tools to avoid breaking plastic clips. Keep fasteners and clips organized for reassembly.
• Support the glass securely when detaching it from the regulator to prevent glass breakage and injury.
• After fitting, check window alignment and smooth travel; adjust guide channels if necessary and lubricate sliding points with an appropriate dry or silicone-based lubricant (avoid heavy grease that attracts dirt).
• Test full travel and safety reversal (if applicable) several times before final reassembly.

Why This Part Commonly Fails

• Cable-Driven Wear: Many regulators use cables and plastic pulleys that can fray, stretch, or break over time—leading to slipping, grinding, or the glass falling out of the track.
• Motor Wear: Repeated use leads to worn brushes and reduced torque in the window motor, causing slow or intermittent operation.
• Water Ingress And Corrosion: Moisture entering the door can corrode fixings and electrical connectors or contaminate moving parts, accelerating failure.
• Mechanical Impact Or Misalignment: Door impacts, slamming with the window partially open, or collapsed guide channels put extra stress on the regulator and shorten its life.

Practical Tips

• If the window moves with noise but still responds, inspect the regulator cables and pulleys before replacing the motor—sometimes the regulator alone is at fault.
• Replace worn felt or rubber guides and keep guide rails clean to extend the life of the new regulator.
• When replacing the regulator, consider checking the condition of the motor connector and door wiring for corrosion to avoid future electrical faults.

Final Notes

This product is supplied as a direct-replacement mechanical assembly for Citroën C1 and Peugeot 107 left front windows (driver door). Use the product codes 9221T8 and 1629054280 when searching for compatibility. Professional installation is recommended if you are not experienced with door trim removal and window alignment.

Overview

This electric front right window regulator is designed as a direct-fit replacement for Citroën C1 and Peugeot 107 models produced until 2013. It restores smooth, reliable operation of the passenger-side front window, replacing worn cables, guides or motor assemblies that cause slow or failed window travel. Ideal for professional workshops and experienced DIY mechanics looking for an OEM-compatible solution identified by part numbers.

Key Benefits

• Direct fit for passenger-side front door of Citroën C1 and Peugeot 107 (pre-2013).
• Restores proper window sealing and reduces wind noise from a misaligned or jammed glass.
• Often searched and ordered by product code (see Technical Information).
• Suitable for technicians and competent DIYers familiar with door trim removal and electrical disconnection procedures.

How It Works

The regulator assembly converts the electric motor’s rotation into linear motion to raise and lower the window glass. Common designs for these models use a cable-and-pulley or scissor mechanism combined with plastic guides and clamps that secure the glass. Wear or damage to cables, plastic slides or the motor will impair movement and can cause the window to become stuck or to drop.

How To Replace

• Prepare: Park vehicle on level ground, engage parking brake and disconnect the negative battery terminal before starting.
• Remove Door Trim: Carefully detach door card and any trim covers to access the regulator and motor. Keep screws and clips organized.
• Support Glass: Secure the window glass in the up position (tape or a wedge) or support it from inside the door to avoid dropping.
• Disconnect Electrical Connector: Unplug the window motor connector and any related switches if required.
• Unbolt Regulator: Remove the fasteners fixing the regulator and motor, then remove the old assembly from the door shell.
• Install New Regulator: Fit the new unit, loosely install bolts, reconnect the motor connector and test operation before final tightening to ensure correct alignment.
• Final Checks: Verify smooth travel, correct seating of the glass in channels, and proper operation of the switch. Refit door trim and reconnect the battery.
• Test Drive: Check function at different temperatures and listen for abnormal noises indicating rubbing or binding.

Technical Information

• Manufacturer: Stellantis (Citroën / Peugeot)
• Model: Citroën C1; Peugeot 107 (up to 2013)
• Product Codes: 9222T6
• Other Numbers: 1629053680, 1689037780

Installation Recommendations

• Always Disconnect The Battery Before Work To Prevent Short Circuits And Avoid Damage To Electrical Components.
• Use Proper Trim Tools To Avoid Breaking Plastic Clips And Panels.
• Support The Glass Securely During Removal And Installation To Prevent Breakage.
• Lubricate Window Channels And Guide Rails Lightly With Suitable Product To Reduce Wear.
• Tighten Fasteners To Manufacturer Specifications Where Available And Ensure All Electrical Connectors Are Fully Seated.

Common Failure Causes

• Worn Or Broken Cables And Plastic Guides — The most frequent cause, especially on older vehicles, leading to jerky movement or a glass that won’t stay up.
• Motor Wear Or Electrical Faults — Reduced motor torque or intermittent electrical connection can prevent smooth operation.
• Corrosion And Water Ingress — Moisture in the door can corrode moving parts and electrical contacts.
• Poor Lubrication And Dirt Build-Up — Grit in channels increases friction and accelerates wear of the regulator components.

Notes For Professionals And DIYers

Part is commonly searched by code 9222T6 and the additional numbers 1629053680 and 1689037780—include these when sourcing replacement units. This regulator is intended for the passenger (right) front door. If you are replacing the unit due to electrical failure, verify power and ground at the connector before replacing the mechanical components to avoid unnecessary parts replacement.

Final Advice

For reliable results, follow manufacturer procedures for door disassembly and reassembly. If you are unsure about the electrical diagnosis or door airbag systems, seek assistance from a qualified technician. Replacing the regulator restores comfort and safety, reducing drafts and preventing the window from becoming inoperable during daily use.
