I've got an issue and wanted to see if anyone had any advice before I go to the dealership. The led turning signals do not work on the outside mirrors. I ordered another set off Amazon to see if it was the mirrors that needed replacing but those did not work either. The power adjust of the mirror works fine, the heated glass works fine, and the blind spot monitor lights as it should. The turning signals on the car work fine. Is there a fuse or relay that controls just those turning signals??
