I've had a non-stop buzzing / humming sound behind my passenger door for days. It occurs when plugged in or not. At the same time, have noticed my charge level drop from what used to be 180 miles to now struggling to get to 170 and usually hanging around 165-163. It's a 2008 Roadster. I've been searching this forum and have seen some comments on cooling fan, but nothing that also had charge levels drop.
Wondering what the experts might think and if there's troubleshooting steps that might make sense. Appreciate the help!
