Description
Rear wiper mechanism for Citroën C5 Estate up to 2007. Bearing is functional, microswitch is functional. Wiper arm and inner cap included.
This rear wiper mechanism is a direct-fit solution for Citroën C5 Estate models and is intended for professional garages and competent DIY enthusiasts. The assembly includes the drive mechanism with a working bearing and microswitch, plus the wiper arm and inner trim cap as listed. Ideal when the tailgate wiper no longer parks correctly, makes noise, or the motor intermittently stops working. Many customers search by part numbers, so the unit is listed under multiple OEM references for quick identification.

Fitment And Use
Designed for rear tailgate applications, this mechanism controls the rear wiper arm movement and park position. It is suitable for replacing worn or intermittent rear wiper systems on the Citroën C5 Estate (first generation). Use the listed product codes to confirm fitment for your vehicle or to locate exact OEM cross-references.
Installation Recommendation
- Prepare: Park the vehicle with ignition off and remove the negative battery terminal if you will be handling the motor connector for extended time.
- Access: Remove the interior trim of the tailgate to expose the wiper mechanism and fasteners.
- Remove Wiper Arm: Pop off the protective cap, loosen the retaining nut, and remove the wiper arm. Note the park position for reassembly.
- Disconnect: Unplug the electrical connector and unbolt the mechanism from the tailgate (typically two or three fasteners depending on variant).
- Replace: Withdraw the old unit, transfer any reusable trim pieces if needed, fit the new mechanism, and secure fasteners evenly.
- Test: Reconnect the electrical plug, cycle the wiper to verify correct travel and park position before reassembling the trim.
- Finish: Refit the inner cap and wiper arm, torque the retaining nut to manufacturer specification if known, and refit the tailgate trim.
Why This Part Commonly Fails
Rear wiper mechanisms typically fail due to a combination of environmental and wear factors: water ingress into the gearbox or motor leading to corrosion, worn bearings that increase friction, degraded microswitches or internal electrical contacts causing intermittent operation, and mechanical wear of gears or linkage. Impact damage from external objects or frozen blades can also bend the arm or damage the mechanism.
Replacing the whole mechanism is often more cost-effective than repairing internal components, especially when the bearing or microswitch is compromised. Regular inspection and keeping seals and drainage holes clear can extend service life.
Suitable for both professional mechanics and experienced DIYers, this assembly is commonly searched and replaced by part number—check the listed codes to match your vehicle application.
