HELP: 1997 Monte No brake lights or interior lights...
 

Hey guys my girlfriend got this car as a freebie from her sister. Its a horror show, it has been sitting ~2-3 years and I started cleaning it up and going over it for her. However I just realized NONE of the interior lights work and the brake lights, with the exception of the 3rd on the rear deck, work. The headlights, turn signals, and 3rd brake light all work fine. All fuses checked out good. She needs to get this inspected and driveable. I did a search and couldnt really come up with anything. Does anyone have any recommendations? Would this most likely be a bad ground or less than perfect battery?

Thanks!!!!
