The Window Switch with OEM code 6552KT is a used original PSA part designed for Citroën and Peugeot vehicles. It is commonly fitted to Citroën Xsara, Berlingo I/II and Peugeot Partner I/II models. This unit replaces faulty electric window control switches without modifications when the part code and connector match the original.

Fitment And Function

This electric window switch operates the up/down movement of the door glass. Typical symptoms of a failing switch include no response, operation only in one direction, intermittent behaviour or a sticking button. On these models failures are frequently caused by worn internal contacts and moisture ingress inside the door.

Installation

Installation is straightforward for professional mechanics and competent DIYers: switch off the ignition (or disconnect the battery for extra safety), pry out the switch bezel from the door trim, unplug the electrical connector, fit the replacement switch and snap the bezel back into place. Some variants may require partial removal of the door card. After fitting, test both directions of window travel to confirm correct operation.

Why Replace

Replacing a defective switch restores reliable window control, preserves the original interior appearance and is usually more cost-effective than replacing larger door modules. Always compare the OEM code 6552KT (or 6552.KT), the number of buttons, the switch housing shape and the connector type with the original unit before ordering to ensure compatibility.
