2 amp fuse

I have a 99 grand prix gtp and i lost power to my stereo, dash board, heater, ac, and to my spedomter thingy. The sterring illumination 2 amp fuse had no power to it. They tested it and it wasnt working. Is this a electrical problem or a fuse problem or is this serious. Please help me i need to fix this. I have no ac and its hot!!!!
