2004 Pontiac Grand Am Grand Am 2004 electrical problems

I'm new to this. Well, its a 4 door Pontiac Grand Am 2004 v6 3.4L. Suddenly, the light from the speedometer/ac/everything inside the car except stereo stopped working which means i have a hard time driving in the night. ALSO The night driving light from the tail lights don't work anymore. They do work when i brake and all of them, but while driving none of them work. ALSO, when i lock the car with the alarm, the lights wont turn on signaling that the car has been locked/unlocked. ALL OF THIS went wrong at the same time... Is it a fuse? Bad wiring? If any, what is it? and thanks in advance appreciate what you guys do.
