Overview
The window control unit is the electronic module that interprets switch inputs and drives the window motor(s). A failing unit can cause windows to stop moving, to operate intermittently, or to behave unpredictably. This replacement Bitron unit is compatible with Citroën Berlingo and Peugeot Partner applications and carries the product references shown below. Please note the wiring harness may not be included with delivery.
Function And Common Failure Causes
- Function: Controls power-window motors and processes switch signals to raise and lower glass smoothly and safely.
- Common causes of failure: water ingress into door electronics, corrosion on connector pins, wiring damage, short circuits, and internal electronic component wear.
- Symptoms of a failing unit: windows stuck in one position, erratic movement, one-touch functions lost or complete inoperability of window switches.
Replacement And Installation Notes
Installation is straightforward for a competent mechanic or experienced DIYer. Typical steps:
- Disconnect the negative battery terminal before starting.
- Remove the door trim panel carefully to access the original control module and window motor connectors.
- Compare the old unit and harness connectors with the replacement to ensure match of plug types and mounting points.
- Disconnect the electrical connectors and any retaining clips, remove the old module and install the Bitron unit, transfer any brackets if necessary.
- Reconnect connectors, temporarily reconnect the battery and test all window functions before reassembling the door trim.
During replacement, always inspect the door wiring and connector seals. In many cases a failed module is accompanied by damaged or corroded wiring that should be repaired to avoid repeat failures.
Condition And Environmental Note
This unit is used but has been tested and functions correctly. Because door electronics are exposed to moisture risks, ensuring good sealing and clean connector contacts during installation will help extend service life.
