Compatibility and standards: Specifically designed for 20092013 Equinox and Traverse models. OEM part number 13581405. Installation and use: Located inside the doors; the actuator to restore proper lock control and trunk operation. Practical use scenarios: 1) Replacing a failed trunk latch actuator to restore remote trunk release on a 20092013 Equinox or Traverse. 2) after the trunk will not lock or unlock from the key fob or interior switch. 3) Part of preventive maintenance or when addressing door lock issues on these model years.
