Installation Recommendations
- Prepare Tools: Basic hand tools, socket set, trim removal tools and torque wrench. Work on a stable lift or with the tailgate securely propped open.
- Removal Steps: Remove the wiper arm by lifting the cap and undoing the retaining nut, then remove the wiper arm. Carefully detach the inner tailgate trim to access the motor assembly. Disconnect the electrical connector to the motor and unbolt the mechanism from the tailgate.
- Installation Steps: Position the new mechanism, secure with bolts, reconnect the electrical connector and refit the inner trim. Reinstall the wiper arm in the parked position and tighten the retaining nut to the manufacturer’s specification. Check that the wiper parks correctly and sweeps the full glass area without obstruction.
- Testing: Operate the rear wiper through several cycles and verify the park position, smooth travel, and that the microswitch engages to stop the motor in the correct position.
Common Failure Reasons
Rear wiper mechanisms commonly fail due to water ingress and corrosion of the gearbox or spindle bearing, causing play or seizure. Mechanical wear of the microswitch or internal gears from age and frequent use can stop the unit from parking correctly. Damage to the external wiper arm, snapped linkage, or stripped splines from excessive force or ice can also lead to replacement. Rodent or debris contamination behind the tailgate trim is less common but can impede movement.
Service Life And Maintenance
Typical service life depends on climate and usage: units in wet, salty environments tend to fail earlier. Inspect the tailgate wiper assembly during routine service intervals for excessive play, noise, or irregular park behavior. Lubrication of accessible pivots and ensuring a watertight inner trim can prolong service life.
This part is supplied with common OEM reference numbers for quick identification: 9651000780, 9637858580, 6405K2 (and related variants). When replacing the mechanism, ensure correct parking alignment and secure fastening to avoid early failure. Suitable for mechanics and competent DIYers familiar with tailgate trim removal and electrical connectors.
