Description
Rear wiper mechanism for Citroën C5 estate up to 2007. Bearing is functional, microswitch is functional.
This rear wiper mechanism is a direct-fit replacement for Citroën C5 estate models produced up to 2007. Designed for workshop professionals and experienced DIYers, the unit restores reliable wiping performance to the tailgate window and eliminates common symptoms such as intermittent operation, grinding noises or a wiper arm that won’t park correctly. The part is suitable when the motor linkage, pivot bearing or microswitch show wear but the electrical connector and mounting points remain intact. Clear listing of product codes makes it easy to search and match the part in catalogs and service databases.
Key benefits: quick swap on the tailgate, robust bearing support for the wiper arm, and an accessible microswitch assembly for diagnostics. The mechanism is compatible with original Citroën mounting points and wiring harnesses used on early C5 estate models, helping maintain correct wipe patterns and park position after replacement.

Installation Recommendations
Intended for fitment by professional mechanics or skilled DIY technicians. Typical replacement steps:
- Disconnect the vehicle battery before beginning to avoid electrical shorts and to protect vehicle electronics.
- Remove the rear wiper arm (usually by removing the protective cap and undoing the retaining nut) and lift the arm clear of the spline.
- Access the mechanism via the tailgate trim panel—remove interior trim clips and screws to expose the wiper motor and linkage.
- Disconnect the electrical connector and remove the mounting bolts securing the mechanism to the tailgate.
- Transfer any serviceable parts (if applicable) or install the complete replacement mechanism, align the park position and torque fasteners to manufacturer specification.
- Reconnect the battery, test full travel and park position of the wiper, reassemble trim and refit the wiper arm ensuring correct arm angle and clearance.
Use suitable hand tools and torque settings. If the vehicle exhibits non-standard electrical behavior after fitment, consult vehicle-specific repair data.
Most Common Causes Of Failure
- Water Ingress And Corrosion: Moisture entry into the motor or pivot area causes bearing and gear corrosion, leading to increased friction or seizure.
- Worn Bearing Or Bushings: Over time the pivot bearing wears, causing play, misalignment and noisy operation.
- Damaged Microswitch Or Internal Contacts: Intermittent or no park detection leads to incorrect stop positions or erratic wiping cycles.
- Mechanical Overload: Frozen glass (ice) or an obstructed wiper arm can overload the mechanism and damage gears or motor.
- Electrical Issues Upstream: Corroded connectors or poor supply can mimic mechanical failure—verify power and ground before replacing the entire unit.
Additional Advice
Check the condition of the wiper arm, blade and tailgate sealing when replacing the mechanism; worn blades or a misaligned arm can accelerate wear. If the bearing and microswitch are stated as functional on this used unit, verify correct operation after installation and ensure the park position is calibrated during final testing.
