Description
Window regulator mechanism for the left rear window for Citroën C5 2001–2007.
This replacement left rear window regulator is designed for Citroën C5 models produced between 2001 and 2007. Ideal for professional mechanics and DIY enthusiasts, the unit restores smooth, reliable up-and-down movement of the rear window and helps eliminate common symptoms such as slow travel, grinding noises or a glass that will not stay in position. Frequently searched by part number (922364), this item fits original equipment spec and is a direct-fit solution for the rear left door on applicable C5 models.
Technical Information
- Manufacturer: Stellantis (Citroën/Peugeot)
- Model: Citroën C5 (2001–2007)
- Product Codes: 922364
- Additional Numbers: NFP
Function And Application
The window regulator mechanism converts the electric motor’s rotation into the linear movement that raises and lowers the glass. The assembly typically includes the regulator track or cable system, rollers or sliders, mounting brackets and the motor interface. This part is specific to the left rear door and designed to work with the factory door glass and electrics of Citroën C5 (2001–2007).
How To Replace (Overview)
- Disconnect the vehicle battery negative terminal before starting to avoid short circuits when working with door electrics.
- Remove the interior door trim and any moisture barrier carefully to access the regulator and motor.
- Lower or support the glass and detach glass mounting bolts from the regulator; secure the glass in position or remove it if necessary.
- Unplug the electrical connector for the window motor and remove mounting bolts securing the regulator mechanism to the door inner panel.
- Extract the old regulator assembly, install the new unit in reverse order, align the glass, tighten fasteners to the correct torque and reconnect the electrical connector.
- Reconnect the battery, test the window operation through full travel to ensure smooth movement and correct seating, then reassemble the door trim and seals.
Installation Recommendations
- Use the correct torque settings for door fasteners to avoid warping the regulator or door panel.
- Lubricate sliding points and guide channels with a suitable silicone-based grease to extend service life and reduce noise.
- Check door wiring harness and connector pins for corrosion or damage and repair as needed before final reassembly.
- If the motor shows signs of excessive load or slow operation, verify window glass alignment and regulator mounting—misalignment increases wear.
Most Common Failure Reasons
Window regulators typically fail due to long-term wear of moving parts (cables, sliders, plastic guides), corrosion from moisture ingress inside the door, or damage to rollers and tracks. Electric motor strain from a misaligned window or obstructed glass path also accelerates failure. Symptoms include intermittent operation, unusual grinding or squeaking noises, slow movement, or the glass not holding position.
For mechanics and experienced DIYers, replacing the regulator with a correctly specified part (see product code 922364) restores original function and prevents further damage to the door electronics and glass mounting points.
