Descrizione
Right front window regulator mechanism for Stellantis vehicles
Front passenger door
Part description
Used right front window regulator mechanism for the front passenger door. The regulator guides and moves the glass as the window is opened and closed. It is a suitable replacement part for addressing a fault that causes the window to move unevenly, jam, or fail to raise properly, if the damaged mechanism is the cause.
The part is listed in the supplied documentation under numbers 9817212280 and 9840175780. When selecting a part, compare the original part number, the mechanism design, and its mounting points. Matching the model range alone is not enough to identify the correct version. The documentation does not state whether an electric motor or any other accessories are included.

Installation recommendations
General guidance for this type of part: replacing a window regulator requires the glass to be secured safely and careful work inside the door. The following procedure is general; the exact trim removal, mounting method, and any window control settings depend on the specific vehicle model and configuration.
1) Before installation
- Verify the cause of the fault. A window that does not work may also be related to the switch, wiring, or drive motor, not just the regulator mechanism.
- Compare the product numbers, installation side, mechanism shape, mounting points, and glass attachment. If an electrical component is present, also compare the connector.
- Inspect the used part: check for deformation, cracks, corrosion, and the condition of the guides and moving parts. For cable-operated versions, also check for fraying and correct cable routing.
- Inspect the glass guides and door seals. Excessive resistance can also damage the replacement mechanism.
2) Tools and materials required
Typically, standard hand tools suited to the door fasteners, a plastic trim removal tool, protective gloves, a means of safely securing the glass, and materials for cleaning the work area are used. Choose materials for resealing the door protective film or barrier according to its design. Handle any non-removable joints in accordance with the vehicle service procedure.
3) Step-by-step installation procedure
- Park the vehicle safely, switch off the ignition, and secure the work area by the door.
- Following the service procedure, position the glass so that its fasteners can be released. Before disconnecting electrical components, disconnect the battery according to the manufacturer’s procedure.
- Carefully remove the door trim. Release the clips without forcing them, and disconnect any connectors by their housings, not by the wires.
- Access the mechanism by removing the relevant covers or protective barrier. Note the wiring route and the arrangement of the fasteners.
- Securely prevent the glass from falling before separating it from the mechanism. Do not rely on the faulty regulator.
- Release the glass from its fasteners according to the design, and keep it safely supported or secured.
- Disconnect any electrical connection, release the mechanism fasteners, and remove it without damaging the glass or wiring.
- Compare the two mechanisms side by side. Clean the mounting surfaces and check that no fragments of the damaged part remain inside the door.
- Install the replacement mechanism without putting it under tension, attach the glass, and restore any electrical connections. Fasten it according to the vehicle manufacturer’s instructions.
- Once the glass is securely fastened, remove its temporary support. Restore the power according to the manufacturer’s procedure and, with the area around the mechanism clear, check that the window operates. Then restore the door seal and reinstall the trim.
4) Post-installation checks and function test
Carefully lower and raise the window several times. Check that it moves smoothly, the glass seats evenly, and there are no unusual noises. If it jams or encounters significant resistance, stop operating it immediately. If the specific vehicle requires initialization of the automatic controls, perform it according to the manufacturer’s instructions. Do not test the anti-pinch protection with your hand. If taking a short drive, also check for rattling in the door and aerodynamic noise around the closed window.
5) Common installation errors and how to avoid them
- Glass not secured sufficiently: secure it before releasing the fasteners to prevent it from falling into the door.
- Mechanism installed under tension: first correctly position all mounting points and the glass, and only then complete the fastening.
- Pinched wiring: route it clear of the glass path and moving parts.
- Resistance in the glass guides not eliminated: before testing, check that the guide surfaces and seals are clean and in good condition.
- Door barrier not sealed: after the work, restore its correct positioning and seal.
Reasons why the part may become damaged
The following are common causes of damage to window regulator mechanisms in general; they do not describe the condition found on this particular part:
- Wear to moving parts and fasteners through long-term use.
- On cable-operated mechanisms, fraying, breakage, or incorrect winding of the cable.
- Increased load due to dirty guides, damaged seals, or frozen glass.
- Moisture and corrosion, especially if the protection inside the door is damaged.
- Incorrectly positioned glass, previous improper installation, or mechanical damage to the door.
- Repeated operation of the window despite jamming, cracking noises, or other signs of a fault.
