Function
The rear wiper motor converts electrical input into rotational motion through an internal gearbox to drive the wiper linkage and arm. It provides intermittent and park positioning so the wiper blade returns to its resting position when switched off, ensuring clear rearward visibility.
Installation Recommendation
Recommended for installation by an experienced mechanic or a competent DIYer with basic tools. Typical steps:
- Remove rear wiper arm (protect the paint and mark arm position for correct refit).
- Open tailgate trim to access the motor and disconnect the electrical connector.
- Unscrew motor mounting bolts and detach the linkage from the motor spline.
- Fit the new motor, ensuring the park position and spline alignment match the original orientation.
- Reconnect the electrical connector and test the wiper operation before reassembling the trim and refitting the wiper arm.
- Replace the washer grommet if damaged; available as ref. 6405EQ.
Use thread locker on mounting bolts if previously applied, protect connectors from corrosion, and apply a light grease to splines during reassembly to prevent seizing.
Most Common Failure Reasons
- Water Ingress: Seal deterioration allows moisture into the motor, leading to corrosion of brushes, commutator, or internal gears.
- Wear Of Brushes Or Commutator: Over time electrical contacts wear, causing intermittent or complete loss of motor drive.
- Gearbox Wear Or Seizure: Mechanical wear or contamination can cause noisy operation or failure to move the arm.
- Connector Or Wiring Corrosion: Poor electrical contact from corroded plugs or terminals results in unreliable operation.
- Frozen Linkage: External linkage or pivot points can seize from rust or debris, overloading the motor and causing premature failure.
Notes For Buyers
Searchable by the listed product codes and compatible vehicle models; keep the numbers handy when ordering or matching parts. The washer grommet referenced as 6405EQ is available separately and recommended to replace if brittle or cracked to prevent future water ingress.
Suitable for professional repair shops and DIY repairs. Replacing a faulty rear wiper motor restores safety by maintaining a clear rear view in adverse weather and extends the service life of the rear wiper system.
