Description
Wiper mechanism for the first series of Citroën C1, Peugeot 107 and Toyota Aygo.
Product Overview
This direct-fit wiper mechanism is designed for the first-generation Citroën C1, Peugeot 107 and Toyota Aygo. It replaces the linkage assembly that transfers motor rotation to the wiper arms, restoring smooth, synchronized wiping action. The part is commonly searched and identified by product codes 6405HT and 6405T0.
Function And Benefits
The wiper mechanism converts the electric motor’s rotary motion into the back-and-forth movement of the wiper arms via a linkage and pivot gearbox. A serviceable mechanism ensures clear visibility in rain and snow, quiet operation and proper park position of the wipers. Replacing a worn mechanism removes play, eliminates erratic motion and prevents damage to wiper arms and blades.
Fitment And Application
Fits: Citroën C1 (first series), Peugeot 107 (first series) and Toyota Aygo (first series). Frequently located and ordered by the product codes 6405HT and 6405T0. Suitable as a direct replacement for vehicles with the original wiper linkage arrangement.
Replacement Procedure
Typical replacement steps for a trained mechanic or experienced DIYer:
- Park vehicle with wipers in the parked position and switch off ignition.
- Mark the position of each wiper arm on the glass to ensure correct reinstallation, then remove the wiper arms (remove retaining nuts and pull off covers).
- Remove the cowl/plenum cover to access the mechanism (may require unclipping trim and removing screws).
- Disconnect the electrical connector to the wiper motor and unbolt the mechanism assembly from the body.
- Remove the old mechanism and fit the replacement assembly, securing all mounting points and reconnecting the motor connector.
- Reinstall cowl and wiper arms in their marked positions, tighten nuts and check that wipers park correctly and sweep the full screen without binding.

Installation Recommendations
Before starting, secure vehicle and follow basic safety rules. It is recommended to disconnect the battery as a precaution against accidental activation of the wiper motor. Mark wiper arm positions on the glass before removal. Inspect wiper motor electrical connector and wiring for corrosion or damage and replace if necessary. Lubricate pivot points lightly with an appropriate automotive grease, and ensure fasteners are correctly seated. After installation, verify full sweep range and park position at low and high speeds. Replace wiper blades if worn to avoid overloading the mechanism.
Why This Part Fails Most Often
Common failure causes include wear of linkage bushings and joints, corrosion from road salt and moisture, ingress of debris or water into the gearbox, and plastic gear wear or breakage. Mechanical overload from frozen or blocked wipers (ice, heavy snow) can accelerate damage. Symptoms of a failing mechanism are unusual noises, loose or jerky motion, incorrect park position or one-sided wiping. Regular inspection and avoiding operating frozen wipers can significantly extend service life.
