The sunroof motor/actuator uses sensor inputs to continuously monitor the location of the glass panel and to establish soft stop locations several millimeters ahead of the hard stops (physical limits) of the glass panel. The sunroof motor/actuator includes the sunroof motor, actuator, sensors and the control module. These components are not serviced individually.
