My headlights are not working?

I have no power inside my car no head lights no brake lights the ac works but thats it the car will start and run fine checked all of my wires all of my grounds had the charging system checked everything passed I can not figured it out please can u help me

Where is the fusable link located? I have no headlights or brake lights.

I had the same problem in a 94 century 3.1 v6. If it wasnt the fusible link then try following the positive connection from the battery. One thick wire runs to the starter and one set of 3 wires runs over to the driverside fender, where the connection off the positve cable is is where my problem was, when I unplugged the connection I could see a "burnt plug", cleaned it up, plugged it back in and all was good from there. I hope this helps.
