same issue(kind of)
Mine too. The speakers dont work, and I have seen what the cause is, just havent fixed it yet. My questions is, what kind of impedence does your ne wspeaker wire have? If it not very good, you could be getting some residual voltage from another wire that is freyed in the door elbow. May have to look at everything in there to be sure thats not the issue.
On the issue of the rear hatch, sorry to hear that. Mine just doesnt work(its loose) and I hope thats the only issue. The guy I got it from has a rope inside to pull it open. I will get to it when the weathers warmer.
You should always be careful. If you're not then someone else won't be, and things are always much, much worse when they happen to you.
