Descrizione
Left rear window regulator mechanism for Stellantis vehicles
Door behind the driver
Part description
The used rear window regulator mechanism guides and moves the glass in the door. It is a suitable replacement when replacing a damaged window regulator, provided it matches the original part configuration. The documentation lists it under numbers 9817212580, 9830335580 and 9840175480 and associates it with the Citroën Berlingo K9, PEUGEOT RIFTER and other vehicles listed below.
Warning about a discrepancy in the side designation: the product name specifies the right rear window, while the original description specifies the left rear window and the door behind the driver. The supplied information therefore does not make it possible to determine the side unambiguously. Before ordering, compare the designation, mechanism shape, mounting points and glass attachment configuration with the original part. Model fitment alone is not sufficient to confirm that the configuration matches.

Installation recommendations
The following general procedure applies to this type of part. The exact method for removing the trim, securing the glass and fastening the mechanism depends on the specific model and door configuration. Follow the vehicle manufacturer’s service procedure.
1) Before installation
- First, verify that the mechanism is actually causing the fault. With electric operation, the cause could also be the switch, power supply, wiring or motor.
- Compare the side, product designation, dimensions, mounting points and glass holders with the old part.
- Check the used part for deformation, cracks, corrosion and damaged mounts. If it has cables, inspect their condition and correct routing.
- If a motor or connector is present, compare its configuration as well. The documentation does not indicate whether these are included.
2) Tools and materials required
A set of screwdrivers and wrenches suitable for the fasteners used, tools for removing the trim, means of safely securing the glass, protective gloves and cleaning supplies are generally used. Select materials for restoring the door’s protective layer according to the specific configuration. Use lubricant only where specified by the manufacturer.
3) Step-by-step installation procedure
- Park the vehicle safely, switch off the ignition and secure the door against unintended movement.
- If possible and safe, position the glass to allow access to its attachment. Do not force a jammed mechanism by operating it repeatedly.
- For electric versions, disconnect the power according to the vehicle manufacturer’s procedure before disconnecting the electrical system.
- Carefully remove the door trim and gain access to the mechanism. Protect the clips, wiring and any protective film or membrane.
- Support the glass securely and prevent it from falling. Only then release its connection to the window regulator.
- Disconnect any electrical connectors, release the mechanism fasteners and remove it without levering against the glass or damaging the wiring.
- Compare the two parts side by side. Also check the glass guide rails and remove any dirt that could cause increased resistance.
- Insert the replacement mechanism and position it without tension. Tighten the fasteners according to the service instructions for the vehicle.
- Secure the glass in its holders, check that it is correctly guided and connect any connectors. The wiring must not interfere with the path of moving parts.
- Remove the temporary glass support, restore the power as specified and carefully test the operation. After a successful check, restore the door’s protective layer and reinstall the trim.
4) Post-installation checks and function verification
Check that the glass moves smoothly without tilting, jerking or unusual noise. Check that it seats correctly against the seal and that the trim is securely attached. If the vehicle uses automatic closing or anti-pinch protection, perform any initialization and checks according to the manufacturer’s instructions; do not test the protection with your hand. A short test drive may reveal rattling or increased aerodynamic noise.
5) Common installation mistakes and how to prevent them
- Confusing the side or configuration: compare the actual part with the old mechanism, especially given the discrepancy in the supplied designation.
- Releasing unsecured glass: always support and secure the glass first.
- Installing the mechanism under tension: check that the mounts are correctly seated and the glass is properly guided before tightening.
- Overlooking binding guide rails: eliminate the cause of the resistance so that the replacement part is not unnecessarily overloaded.
- Damaging the door’s protective layer: restore its correct fit and seal to prevent water from reaching the trim and electrical connections.
Reasons why the part gets damaged
The following causes of damage can generally occur with window regulator mechanisms; this is not a description of the condition found on this particular part:
- Wear of moving parts, holders and any cable drive due to prolonged use.
- Increased resistance of the glass caused by dirt, damaged guides or deformed seals.
- Operating a frozen or otherwise blocked window.
- Moisture and corrosion affecting the moving parts of the mechanism.
- Incorrect previous installation, misaligned glass or excessive strain on the mounts.
- Mechanical damage to the door or impact to its structure.
