So my 2014 Ford Fusion, which i do really like, has this passenger side mirror issue. I found that it does not work, while everything else on the same fuse does. So i have been able to decide the fuse is fine. There is no physical damage, is there some place to check for a wiring fault? How should I look into diagnosing the issue? I miss having the window defrost the most here in New England. Luckily the mirror is stuck in a usable position.
