I need to replace these units on the other side of my 08 LC where they are missing due to damage.....they are mounted to the rear quarter panel behind the bumper cover. One looks like it may actually do something (the one marked "2R") the other appears to just be a cover for a hole (???). Any idea what these are called or what they do? Trying to find them on exploded parts diagrams and not having any luck. Just trying to order new ones (or from salvage pulls). Thanks!
