Mine finally worked this weekend when I drove through some rain. I was also confused having them on the bottom thinking it was automatic but it never came on. Changed all 3 driver settings to have automatic wipers on and then turned the dial to the raindrop and it actually worked. I also had another issue so I disconnected the battery for 40mins last week to reset the blind spot (which didn’t work) so maybe that helped it out?
I would try settings in driver profiles and then put it on raindrop and see what happens.
