Description
Sunroof electric motor for Peugeot 407 cars
Part description
Are you looking for a reliable replacement for a malfunctioning sunroof drive? This Webasto electric motor is designed for the Peugeot 407 and solves typical sunroof defects such as reluctance to move, jamming or complete inoperability of the movement. Thanks to the searchable codes 96836298BJ and 8401VS, you can easily compare the correctness of the part with the existing unit in the car.
It is a used car part suitable for mechanics and home repairs – an ideal choice if you need to quickly restore the function of the sunroof without unnecessary costs.

Installation recommendations
Generally/typically for the sunroof electric motor, the exact procedure may vary depending on the design of the roof mechanism and the car’s equipment. Below is a practical universal procedure that will help prevent damage to both the mechanics and the wiring.
1) Before assembly (checks of the used part, what to compare with the old part)
- Compare the part codes (96836298BJ / 8401VS) with the label on the original engine or with the marking in the mechanics.
- Check the connector (shape, number of pins) and the condition of the pins (oxidation, bending).
- Inspect the motor body, mounts and shaft/drive: cracks, squeezed bearings, signs of overheating.
- If the problem was “only” jamming, consider also checking the mechanics of the sunroof (guides, cables) – the engine often goes out secondary.
2) Necessary tools and materials (in general, without specific extra parts)
- Basic set of screwdrivers and attachments (according to the type of screws in the car)
- Plastic pry bar for removing interior covers
- Flashlight
- Contact cleaner (optional) and a clean cloth
3) Step-by-step assembly procedure
- Turn off the ignition and disconnect the battery (to protect the wiring and risk of short circuit).
- Give access to the sunroof motor – typically by removing the relevant interior cover/part of trim (procedure varies by design).
- Before disconnecting, make a note of the wiring route and the position of the connector so that you return everything without strain.
- Disconnect the engine electrical connector; if it’s stiff, don’t pull on the cables – loosen on the body of the connector.
- Loosen the engine fasteners and remove the engine carefully so as not to damage the sunroof mechanism.
- Compare the old and new piece “on the table”: mount, connector, driver/shaft.
- Place the new electric motor in the same position as the original, without force and without crossing the attachment.
- Tighten the fastening evenly (without pulling so as not to deform the fit).
- Connect the connector and check that it is properly engaged and that the wiring does not rub or break anywhere.
- Reinstall the removed covers/upholstery so that nothing obstructs movement and does not create tension.
- Connect the battery.
-
4) Post-assembly checks and test drive/function verification
- Verify the opening/closing function – watch for smoothness, unusual noises and possible jamming.
- If the visor moves jerkily, stops or is very noisy, check the mechanics (guides/cables) and the patency so that the motor is not overloaded.
- After a short ride, recheck that nothing vibrates and the covers are properly seated.
5) The most common assembly mistakes + how to avoid them
- Disconnecting the connector by the cables → always release the connector by its body.
- Assembly without checking the mechanics → stiff guides/cables can destroy even a functioning engine.
- Bad engine seating → can cause noise, skipping or damage to the driver.
- Pinched wiring → after assembly, check that the cables are not rubbing anywhere and are not under tension.
Reasons why the part is damaged
- Motor overload due to stiff or damaged sunroof mechanics (guides, cables, lines).
- Ingress of moisture and subsequent corrosion of connectors or internal parts.
- Wear of transmission parts during frequent use or during operation with increased resistance.
- Electrical problems (oxidation of contacts, contact resistance, power fluctuations) that lead to erratic operation and heating.
