Headlights, tail lights, signal radio and A/C blower not working

I recently just purchased this vehicle from someone who's husband just passed and the cars been sitting. She doesn't know anything about the car just that it's been one owner. Everything runs fine but I ran into an issue which I forgot to check upon purchase . It was very cheap so I thought I'd take my chance .
Anyways here is the issue: Headlights , signal ,hazards radio and A/C blower all wont turn on. No tail lights either. I checked all fuses and all seem to be good. Is there another way to diagnose this issue and maybe get a diagram of where these fuses and wires are supposedly located? Dash lights are on the A/C light is on but no interior lights bulbs are good. Radio wont turn on at all power locks don't work but windows work . maybe you might have a bigger question as to what might be happening and what I can do? Thank you in advance.
