Peugeot 407 SW rear wiper motor 9646500880 54906212 6405R1

Description

Rear window wiper motor for PEUGEOT 407 SW cars

Part description

The rear wiper motor is a key part of the wiper mechanism, which ensures smooth movement of the rear wiper blade and thus a good rearward view in rain or snow. This used part is intended for the Peugeot 407 SW and is suitable as a replacement in the event of a defect in the original motorcycle (e.g. non-functioning, weak running or irregular wiping).

When choosing, the most important thing is to follow the product number, because it often differs depending on the design.

Installation recommendations

Generally/typically the replacement of the rear wiper motor is carried out following the removal of the trim part in the area of the rear window/fifth door and the disconnection of the electrical connector. The exact procedure may vary depending on the specific design of the car and the wiper mechanism.

1) Before assembly (checks)

• Compare old and new part: connector match, mount and number 9646500880 / 54906212 / 6405R1.
• Check the condition of the connector and pins (oxidation, loosening, damage).
• Check if the motor output shaft/axes do not appear to be stuttering (when manually rotated according to design).

2) Necessary tools and materials

• Basic set of ratchets and extensions / keys
• Screwdrivers and crowbars for plastic upholstery
• Electrical contact cleaner, cloth
• Protective gloves

3) Step-by-step assembly procedure

1. Turn off the ignition and secure the vehicle against movement.
2. Disconnect the battery (minimizing the risk of a short circuit when working on the wiring).
3. Remove the necessary inner trim in the area of access to the rear wiper motor (careful because of the clips).
4. Disconnect the motorcycle electrical connector.
5. Undo the fasteners and remove the original motor.
6. Check the surroundings: grommets, wiring, any traces of water/oxidation and clean everything.
7. Install the new motor in its original position and fasten it in the same way as the original part.
8. Connect the electrical connector and check that it clicks properly.
9. Namontujte zpět demontované obložení.
10. Connect the battery.
11. Perform a functional test of the rear wiper (operation, fluidity, irregularities).

• 4) Post-assembly checks and function verification

  • Verify that the wiper runs smoothly and without unusual noises.
  • Check that the connector is not hot and that the wiring is not under tension.
  • After a short ride, check again that everything holds and nothing vibrates.

  5) The most common assembly mistakes + how to avoid them

  • Exchanging a part without checking the numbers → always compare the codes and the connector.
  • Damage to plastic trim clips → remove with an upholstery pry bar and do not pry with force.
  • Not solving the oxidation of the connector → clean the contacts, check the pins.
  • Installation without disconnecting the battery → risk of short circuit and other defects in the electrical installation.

  Reasons why the part is damaged

  • Intrusion of moisture into the mechanism area and subsequent corrosion/oxidation of the contacts.
  • Mechanism load (frozen wiper blade, snow/ice on the glass) leading to motorcycle overload.
  • Wear of the internal parts of the motorcycle due to age and operation.
  • Increased resistance of the mechanism (links/axle stuttering) – the motor then works in unsuitable conditions and can go away.
  • Problems in the electrical installation (loose or oxidized connectors) that cause blackouts or erratic operation.
