Alright, Just bought a 1999 Grand Prix GT. The 6"x9"'s in the rear are not putting out anything at all. And the truck wont open with the Glove Box button, Key Fobs, or with just the key. I'm trying to figure out if they're related or what? I was thinking fuse till the truck wouldn't open even with the key. So any advice on both? Any known wiring problems in the trunk?
