Lights wont go off, among otherthings.

[gigdy]

So I went to turn my overdrive off the other day and found it didnt work. So i check all my fuses and find the blown one, so i replaced it. But that didnt fix it. I eventually figured out why, the fuse that control it also controls my back up lights, and for some reason now every time i put it in reverse the fuse blows. So i finally figure this out and figure theres not really much i can do, so i shut my car off and the lights wont go off. So i figure some relay is fried and now have to unhook the battery when i turn the car off. Hurrrrray :cry:
