1985 Eldorado electrical issues
 

I just purchased a '85 Eldorado coupe, the car is in decent condition with 50K miles on it. However, the interior lights, the trunk release button in the glove box and the radio don't work. The radio antenna does go up when turned on, you just don't get any understandable reception which makes me think it might be an antenna connection? I did find a blown fuse for the interior lights but that didn't help. Any help or direction will be much appreciated.
