The aircon is not covered by LR diagnostics, not conncted to the K line... it has it's own protocol but it will detect only open or short circuit and if it was that you can't see any temp reading just two lines, all you can do is to replace the outside air temp sensor(the one behind the grill)...eventually blow on it with a hair drier to see if it reacts to it or not
