Product Overview
This replacement electric motor drives the left rear sliding door (door located behind the driver) on Citroën C8 and Peugeot 807 models.

Function And Application
The motor converts electrical input into mechanical rotation to operate the sliding door gearbox and track mechanism. It provides the torque required to overcome door weight and friction in the slide mechanism while working with door limit switches and safety cutouts. Proper operation depends on intact wiring, a secure mechanical connection to the door gearbox, and correct alignment of the sliding track.
