electrical wiring,Gear stuck on park. Brake lights dont turn on. Brake light switch has been changed the problem still remains.

Hi, so my gear got stuck on drive the other day and when i got home to put it into park i couldnt get past nuetral. I then engaged the shift lock and moved it park. After further inspection i saw my brake lights do not come on. So i changed my brake light switch and the problem still remained. I then proceeded to my interior fuses changing 3 since my voltometer didnt light up. After changing the fuses the brake lamp fuse and another still didnt light up. Do you have ideas as to what could be the problem. Thank you very much.

My car has 200000 miles.
