Land Rover Part Number: RTC6640 - Left-Hand Front Door Window Motor
RTC6640 is a left-hand front door window motor fitted to the front left door regulator on Range Rover Classic models. The motor converts electrical input from the door switch into rotational torque that drives the regulator drive gear or cable spool to raise and lower the window glass; it mounts to the regulator plate inside the door and connects to the door wiring harness via a multi-pin electrical connector and toothed drive interface. Replacement is required when the motor fails to move the window, produces grinding, operates intermittently, or gives no response despite correct power at the connector - when fitting, check the regulator mounting points and electrical connector condition to avoid premature wear.
