Land Rover Part Number: CUR100450 - Left-Hand Window Regulator Motor - Side Doors
CUR100450 is a left-hand window regulator motor for side doors. Fitted to the left-hand front or left-hand rear door on applicable Discovery models with powered windows, the unit converts electrical input into rotational drive to operate the regulator gear or cable and move the door glass. The motor matches the regulator mounting and electrical connector patterns used on the listed Discovery years. Replacement is required when the drive fails, the motor gearbox seizes, or the electrical winding no longer produces sufficient torque to move the glass; the corresponding right-hand motor is CUR100440, so check door orientation and regulator type before ordering.
