• Additional Numbers: 1488958080; NFP

Compatibility And Application

Fits as the washer hose grommet/pass-through in the rear tailgate for Citroën C8 and Peugeot 807. The part seals the aperture where the washer hose passes through the tailgate sheet metal and supports the rear washer nozzle tubing to prevent chafing and leaks.

Function And Benefits

• Seals the washer hose entry point to prevent water ingress and corrosion inside the tailgate.
• Prevents washer hose chafing and mechanical wear by securing the hose in place.
• Maintains correct washer fluid routing to the rear nozzle for reliable cleaning performance.
• OEM-referenced fitment for straightforward identification and ordering by part number.

Replacement Procedure

Basic Steps (Typical For Tailgate Installations):

• Remove Tailgate Trim: Open the tailgate and carefully remove the interior trim panel to access the wiper motor and hose routing. Keep fasteners organized.
• Remove Wiper Arm/Nozzle If Necessary: Depending on access, you may need to remove the wiper arm or nozzle to free the hose and grommet area.
• Disconnect Washer Hose: Carefully detach the washer hose from the grommet/nozzle. Prepare a small drain container to catch residual fluid.
• Extract Old Grommet: Push or pry out the old grommet from the tailgate aperture. Inspect the hole for rust or deformation and clean the mating surface.
• Fit New Grommet: Lubricate the new grommet lightly with silicone grease or soapy water for easier installation, then press it into the aperture until fully seated.
• Reconnect Hose And Reassemble: Reconnect the washer hose, route it to avoid kinks, reinstall any removed components and the trim panel. Refill washer fluid if needed and test the rear washer for proper flow and sealing.

Installation Recommendations

• Use Silicone-Based Grease: A light coating of silicone grease helps install the rubber grommet without degrading the material.
• Inspect Hose And Clamps: Replace brittle or cracked hose sections and faulty clamps to prevent repeat leaks.
• Check For Corrosion: Clean and treat rust around the aperture before fitting the new grommet to ensure a durable seal.
• Test After Fitment: Operate the washer system and inspect for leaks at the grommet and along the hose routing.
• Safety Note: If Working Near Electrical Components, Isolate The Negative Battery Terminal As A Precaution.

Common Failure Modes

Rubber grommets in the rear washer system typically fail due to age-related degradation, UV exposure, and repeated mechanical stress. Common causes include:

• Rubber Hardening And Cracking From Heat And UV Exposure, Causing Leaks.
• Hose Wear Or Abrasion Against The Tailgate Edge When The Grommet Loses Its Cushioning Effect.
• Damage From Ice Or Debris, Especially In Cold Climates Where Water Can Freeze In The Hose Or Nozzle.
• Corrosion Around The Aperture That Prevents Proper Sealing.

Why Replace This Part

A failing grommet often leads to washer fluid leaking into the tailgate cavity, which can cause corrosion, impair rear wiper motor operation, and create electrical issues in connectors housed inside the tailgate. Replacing the grommet is a cost-effective preventive repair to maintain washer performance and protect bodywork and electronics.

Final Notes

Suitable For Professional Workshops And Skilled DIYers. Installing a correct-fitting grommet restores a watertight seal and prolongs the service life of rear-wiper components—important maintenance when preserving the integrity of tailgate electronics and body panels.

Product Overview

Direct-fit rear wiper motor designed for Citroën C8 and Peugeot 807 models. This robust electric motor drives the tailgate wiper arm and is identified by common OEM references 53015412, 1484603080 and 6405K9. Supplied without the washer fluid connector (reference 6405L0), which is available as a separate part. Suitable for professional garages and experienced DIYers who perform bodywork electrics and wiper mechanism repairs.

Technical Information

• Manufacturer: Stellantis / Citroën / Peugeot
• Model: Citroën C8, Peugeot 807
• Product Codes: 53015412, 1484603080, 6405K9
• Other Numbers: 6405L0 (Washer Connection, Sold Separately)

Function

The rear wiper motor provides the rotational torque required to move the tailgate wiper arm across the rear glass, ensuring water and dirt are cleared for rear visibility. It interfaces with the wiper linkage and the vehicle wiring harness and is actuated via the wiper control stalk or vehicle body control module depending on model specification.

Common Failure Causes

Failures typically arise from water ingress and corrosion, worn brushes or commutator inside the motor, stripped or broken internal gears, or mechanical seizure of the linkage. Additional causes include electrical issues such as a corroded connector, intermittent supply voltage, or excessive load from a frozen/blocked wiper arm.

Replacement Guide

General replacement steps (for experienced technicians):

• Disconnect the vehicle battery before starting to avoid short circuits and protect vehicle electronics.
• Remove the interior tailgate trim to access the motor; retain all clips and screws in order.
• Mark the wiper arm position on the spline or glass to ensure correct reassembly alignment.
• Disconnect the electrical connector and unbolt the motor from the tailgate.
• Transfer any required linkage components or fastening hardware to the new motor if applicable.
• Install the new motor, reconnect the wiring, reposition the wiper arm to the marked position and test the function before reassembling the trim.

Mounting Recommendations

Always follow the vehicle manufacturer’s torque settings and reassembly procedure for tailgate panels and trim. Ensure connector contacts are clean and protected from moisture; apply dielectric grease to terminals where appropriate. After installation, verify full sweep and park position of the wiper to avoid motor overload. If the washer fluid connector (6405L0) is required, fit it and check the sealing to prevent water ingress into the motor area.

Durability and Service Life

Service life depends on usage and environmental exposure. In normal conditions, rear wiper motors can last many years, but repeated exposure to moisture, road salts and mechanical strain can shorten lifespan. Inspect linkage and seals during replacement to prevent premature failure of the new unit.

Why Buy This Part

Ideal for professional repairs and competent DIY maintenance. Using the correct OEM-referenced motor (53015412 / 1484603080 / 6405K9) ensures a precise fit and restores reliable rear wiper operation on Citroën C8 and Peugeot 807 models. Fast replacement reduces downtime and improves rear visibility and safety.

Ordering Note

Search by product codes 53015412, 1484603080 or 6405K9 to find this exact rear wiper motor. If you require the washer fluid connector, order part 6405L0 separately.
