Function And Common Faults

The rear wiper mechanism transfers rotary motion from the motor into the sweep movement of the wiper arm and contains internal gears, bearings and a microswitch that detects park position. Typical failure modes include gear wear or stripping, bearing seizure from corrosion or contamination, water ingress into the motor/gearbox and failure of the park microswitch. When these components deteriorate, symptoms include noisy operation, incomplete sweep, wiper arm not parking correctly, or complete loss of rear wiper movement.

Replacement Procedure (Overview)

Replacement is straightforward for experienced technicians and competent DIYers with basic workshop tools:

• Remove The Rear Wiper Arm: Pry off the wiper cap, remove the retaining nut and lift the arm free.
• Remove Tailgate Trim: Open Tailgate And Carefully Remove Interior Trim Panel To Access The Mechanism (Retain Clips And Fasteners).
• Disconnect Electrical Connector: Unplug The Wiper Motor Connector And Any Linked Harnesses.
• Unbolt The Mechanism: Unscrew Fasteners Holding The Gearbox/Mounting Plate, Free The Unit From The Tailgate.
• Install New Unit: Position The Replacement Mechanism, Tighten Fasteners To Manufacturer Torque Where Available, Reconnect Electrical Connector.
• Refit Trim And Wiper Arm: Reinstall Interior Trim, Refit Wiper Arm To Correct Park Position And Secure Nut.
• Function Test: Cycle The Rear Wiper To Confirm Sweep Range, Park Position And Absence Of Unusual Noise.

Installation Recommendations

• Disconnect The Battery Before Starting Work To Avoid Short Circuits And Unintended Motor Operation.
• Protect Interior Trim Clips And Fasteners During Removal To Prevent Breakage.
• Check The Wiper Arm Splines And Replace The Arm Or Washer If Excessive Play Is Found.
• Ensure The Mechanism Is Correctly Aligned So The Wiper Parks In The Designated Position.
• Apply Dielectric Grease To Electrical Connectors If Corrosion Is Present; Lubricate Pivot Points With Suitable Grease During Reassembly.

Why The Part Most Commonly Fails

Rear wiper mechanisms are exposed to weather, road salt and moisture, which promote corrosion and contamination. Repeated mechanical load and occasional shock (ice, blockage) accelerate wear of plastic or metal gears and bearings. Water ingress can short the motor or cause the park microswitch to fail. Lack Of Lubrication And Physical Damage From Snow/Ice Are Frequent Causes Of Premature Failure.

Replace your faulty right (passenger-side) front wiper motor with a reliable Bosch unit designed to restore smooth, quiet wiping and secure park positioning on Peugeot 407 vehicles. This electric motor drives the wiper linkage to clear the windshield, improving visibility in rain and adverse weather. The part is commonly searched by its product codes, so including these identifiers improves findability for mechanics and DIY enthusiasts looking for a direct replacement.

Key Features

High-quality electric drive from a reputable supplier, built to interface with the Peugeot 407 wiper linkage. Designed for the passenger-side front wiper, the motor provides the torque and intermittent operation needed for safe, reliable wiping performance.

Typical Symptoms Indicating Replacement

• Wiper Arm Does Not Move Or Moves Intermittently
• Unusual Grinding Or Clicking Noises From Under The Cowl
• Wipers Stop In Wrong Park Position
• Slow Wiper Movement Or Loss Of Intermittent Function

How The Part Works

The wiper motor converts 12 V electrical energy into rotary motion, transmitted through an integrated gearbox and a linkage assembly to move the wiper arm across the windshield. Proper park position is managed by internal mechanical stops or an internal parking circuit so the wipers return to their rest position when switched off.

Installation Recommendations

• Disconnect The Battery Before Starting Work To Avoid Short Circuits.
• Remove Wiper Arms And Cowl Cover To Access The Motor And Linkage.
• Mark The Wiper Arm Position Before Removal To Ensure Correct Reinstallation And Parking Alignment.
• Disconnect Electrical Connector And Remove Mounting Bolts; Fit New Motor In Reverse Order.
• After Installation, Reconnect Battery And Verify Correct Wiper Park And All Speeds/Intermittent Settings Work Properly.
• Check Fasteners And Connector For Corrosion; Replace Any Damaged Clips Or Seals To Prevent Water Ingress.

Why This Part Most Often Fails

Wiper motors commonly fail due to brush wear inside the electric motor, water ingress leading to corrosion of electrical contacts or gearbox components, mechanical overload from frozen or obstructed wipers, and long-term wear of internal gears. Environmental exposure (rain, road salt) accelerates deterioration of seals and electrical connections, making the motor more susceptible to faults.

• Additional Numbers: 3397020604, 390241968, 6405GL, 6405GN, 9656859980

Function And Typical Symptoms

The wiper motor converts electrical energy into rotary motion that drives the wiper linkage and arms, ensuring correct sweep and park position. Common symptoms of a failing motor include no movement of the left wiper, slow or intermittent operation, unusual grinding or clicking noises, and failure to park in the resting position. Because the motor is integrated with the wiper linkage, symptoms can mimic mechanical binding or linkage wear.

Installation Recommendations

Installation should be performed by a competent technician or an experienced DIY mechanic. Typical replacement steps:

• Disconnect the battery negative terminal to avoid short circuits.
• Remove Left Wiper Arm: Mark and remove the wiper arm from the splined shaft (retain any caps or fasteners).
• Remove Cowl/Trim: Take off the lower cowl/grille panels to access the wiper motor and linkage.
• Disconnect Electrical Connector: Unplug the motor wiring harness carefully.
• Unbolt Motor: Remove mounting bolts securing the motor to the body or gearbox and separate the motor from the linkage.
• Fit New Motor: Position new motor, secure bolts, reconnect electrical connector and reassemble cowl and wiper arm.
• Adjust And Test: Reconnect battery, cycle the wipers to check sweep, park position and ensure no binding. Refit wiper arm to correct angle on the splines.

Avoid forcing the linkage when refitting. If the linkage is corroded or seizing, lubricate or replace affected components to prevent premature motor overload.

Why This Part Most Commonly Fails

Wiper motors commonly fail due to a combination of mechanical wear and environmental factors. Typical causes include worn carbon brushes and commutator wear inside the motor, water ingress leading to corrosion of the motor or gearbox, seized linkages that overload the motor, and electrical faults such as connector corrosion or wiring damage. Heavy use in winter conditions, frozen windscreen loads and prolonged exposure to moisture accelerate wear.

Practical Notes

When replacing the motor, inspect the wiper linkage, splines and mounting points. Replacing only the motor while the linkage is corroded may lead to quick recurrence of the fault. This part is often searched and ordered by its product numbers—include these codes when searching to ensure a correct match.
