Fried Electrical Harness?

gryffin13

Hey, so I was attempting to wire in a radar detector and a dash camera into the power lines running to my mirror. I thought I had everything perfect but as I was making the final installation I think I must have shorted something. I connected it and they both turned on, but then lost power and now I don't have power to the mirror, my heater/AC, my heated seats, and my sport-mode button. (I have a sport package+touring coupe).

At first I assumed (and hoped) that I just blew a fuse, but I checked and all are in tact.

So a couple questions that I'm hoping maybe someone here has the experience to answer as I've tried to google it and can't find what I'm looking for. 1) Based on the components that I've lost power to, is there a specific harness/component that I've likely ruined? 2) Any recommendations on how to go about fixing? Is this the kind of thing that is a big enough deal I really need to bring to a dealership?

Any info is appreciated - thanks!
