No Dash Lights, No tail Lights

I have been having wierd illumination problems with my van. I have a 1996 Astro AWD and First my stereo amp kept blowing a fuse, then a few days later the ac/heater started acting as if it was hooked up wrong, then the blinker on the passenger side started blinking fast and now the Dash lights have gone out and the running lights for the tail lights are out still have brake lights and reverse lights. I started at the fuse box but all the fuses are good. Any ideas where to start next?
or is the van just haunted?
