Hello, I just bought a used Qashqai (the smallest one, built in 2016). I would have to find out with horror that there is no rain sensor in there, at least I have no “car” adjustment on the lever for the windscreen wiper. Out of curiosity I have seen what is behind the rear-view mirror. See photo. Is there a rain sensor installed or not (the round?). Unfortunately I couldn’t find anything on the Internet. Maybe it just needs to be connected? Thanks
