Description
Rear Wiper Mechanism For Citroën C5 Estate Up To 2007. Bearing Is Functional, Microswitch Is Functional.
Product Overview
This used rear wiper mechanism is suitable for Citroën C5 estate models up to 2007 and carries original Stellantis/Citroën part references. The unit drives and guides the rear wiper arm, converting the motor output into the oscillating movement that keeps the rear window clear. Bearing and built-in microswitch are reported functional, which reduces the amount of additional work required at installation.
Key Features & Benefits
- Direct Fit For Specified Citroën C5 Estate Models — simplifies replacement for workshops and DIY mechanics.
- Includes Functional Bearing And Microswitch — lowers the chance of immediate secondary failures.
- Supplies Same Mechanical Interface As Original Equipment — no modifications typically required.
- Commonly Searched By Part Numbers (Good For SEO): 9651000780, 9637858580, 6405K2, 6405K3, 6405K4, 6405K5, 6936C2.
Function
The mechanism converts rotational motion from the rear wiper motor into the back-and-forth sweep of the wiper arm. The integrated bearing supports the pivot and the microswitch (park switch) signals the wiper control when the arm has returned to its rest position. A correctly functioning mechanism ensures smooth, noise-free wiping and reliable park detection.

Common Failure Modes
- Water Ingress And Corrosion — Causes Seized Pivot, Noisy Operation, Or Electrical Shorting.
- Worn Or Damaged Plastic Gears — Results In Slipping, Intermittent Movement Or Complete Loss Of Motion.
- Failing Bearing — Produces Excessive Play And Noise, Alters Wiper Sweep Geometry.
- Malfuctioning Microswitch (Park Switch) — Leads To Incorrect Park Positioning Or Wiper Not Returning To Rest.
Replacement Guide
Basic Steps For Removal And Fitment (Typical Procedure):
- Remove The Rear Wiper Arm: Pry Off The Protective Cap, Unscrew The Retaining Nut, And Withdraw The Arm From The Spindle.
- Remove Tailgate Trim: Open Tailgate And Carefully Remove Interior Trim To Access The Mechanism. Keep Fasteners And Clips Organized.
- Disconnect Electrical Connector: Unplug The Wiper Motor Connector To Avoid Short Circuits.
- Unbolt The Mechanism: Remove Mounting Bolts/Screws Securing The Assembly To The Tailgate And Extract The Unit.
- Fit New Mechanism: Position The Replacement, Tighten Fasteners To Manufacturer Torque Where Available, Reconnect Electrical Connector, Refit Trim And Wiper Arm. Check Wiper Park Position And Sweep.
Installation Recommendations
- Wear Gloves And Eye Protection. Handle Plastic Trim Clips Carefully To Avoid Breakage.
- Before Reassembly, Check The Tailgate Sealing Areas And Clean Any Corrosion To Prevent Future Water Ingress.
- Verify Electrical Connector Pins Are Clean And Free Of Corrosion. Use Dielectric Grease If Appropriate.
- After Installation, Cycle The Wiper Several Times To Confirm Correct Park Position And Smooth Operation. Adjust Wiper Arm Position If Required.
- Disconnect The Battery If Working Near Multiple Electrical Systems For Added Safety, And Follow Standard Workshop Procedures.
Why This Part Most Often Fails
Rear wiper mechanisms are exposed to weather and road contaminants. Water ingress and salt accelerate corrosion of metal parts and degradation of grease, while UV and age can embrittle plastic gears. Repeated loading from frozen or obstructed wipers increases mechanical stress on the gearbox and bearings. The microswitch may wear out from repeated cycles or fail due to moisture and corrosion.
Notes For Professionals And DIYers
This unit Is Suitable For Mechanics And Competent DIYers. Always Confirm Visual Fit And Part Numbers Before Installation. If The Wiper Motor Or Electrical System Shows Related Faults, Diagnose Those Items In Parallel To Prevent Repeat Failures.
