Description
Rear wiper mechanism BOSCH PEUGEOT 407 SW. Bearing is functional, microswitch is functional.
This Bosch rear wiper mechanism is a direct-fit solution for Peugeot 407 SW owners and professional garages. Designed to restore reliable wiping performance on the tailgate, the unit includes the motor-driven mechanism, bearing and microswitch (park sensor). Ideal for mechanics and competent DIYers, the part is often searched and ordered by its product numbers, so you will find the correct match quickly using the codes listed below.
The rear wiper mechanism converts electrical input from the wiper switch into rotational motion that moves the wiper arm across the rear window. The integrated microswitch detects the park position and stops the motor precisely when the blade returns to rest. A functioning bearing ensures smooth, low-friction rotation and reduces wear on the linkage and motor. Replacing the mechanism restores correct sweep angle, prevents rubbing or stalling and eliminates intermittent or non-parking wiper behaviour.

Installation Recommendations
- Remove Wiper Arm: Pry off the cap and undo the retaining nut, then remove the wiper arm.
- Trim And Access: Fold or remove the tailgate trim to access the mechanism mounting and electrical connector.
- Disconnect And Unbolt: Disconnect the electrical plug, mark the park position if needed, and unbolt the mechanism from the tailgate.
- Fit New Unit: Fit the replacement mechanism, align to the correct park position, tighten fasteners securely and reconnect the electrical connector.
- Test And Adjust: Refit the wiper arm, set it to the correct angle, test full travel and park function. Check for smooth operation and absence of binding.
- Safety Tip: Work with the battery isolated when disconnecting electrical components if needed and avoid forcing linkages to prevent damage.
Most Common Failure Causes
- Water Ingress And Corrosion: Moisture entering the motor or gearbox corrodes contacts and gears, leading to intermittent operation or seizure.
- Worn Microswitch Or Contact: The park-detect microswitch can wear out, causing the wiper to fail to park or to stop in the wrong position.
- Damaged Linkage Or Stripped Gears: Mechanical wear or shock can strip plastic gears or bend linkages, producing slack, noise or loss of movement.
- Bearing Wear: A worn bearing creates increased friction and can overload the motor, accelerating failure.
- Electrical Issues: Corroded connectors or poor grounding reduce power to the motor and cause unreliable function.
Notes For Buyers: This part is commonly searched by its part numbers (listed above). Confirm fitment for Peugeot 407 SW models when ordering by verifying the part numbers match the vehicle’s existing unit. Suitable for professional installation or experienced DIYers familiar with tailgate trim removal and electrical connectors.
