The window regulator assembly (CUH500220) is the mechanical mechanism responsible for raising and lowering the front right-hand door glass on the Range Rover L322. This unit controls the electric window lift via a motor-driven cable or scissor mechanism, and failure typically presents as a slow-moving, stuck, or completely inoperative window. Fitting the correct side-specific, non-armoured variant is essential to ensure proper motor alignment and cable routing within the door cavity. Key Features Right-hand fitment - not interchangeable with the left-hand or armoured door regulator variants Designed for standard (less armoured) door construction, which differs internally from armoured body variants OEM specification part matching original geometry, cable tension, and motor mounting points When replacing the regulator, inspect the window motor and door glass channel guides for wear, as these components commonly fail concurrently Vehicle Fitment Fits Range Rover L322 (2002–2009), right-hand front door, less armoured body specification, vehicles up to VIN suffix 9A999999.
