1989 Chevy Astro dome lights, cig lighter, glove box lights

. i was using cig. lighter heater/defroster and shut it off when the car was not running(i normaly do so while it is still on) something tripped/shorted and now my cig lighter, inside lights, and radio/ radio lights do not work. there is power going to the radio, i can hit the poser button and the speakers get power, but not the radio itself. also my dome light can be set to an on position with my dimmer wheel/switch, and while i can dim my dash lights still, i can not turn on my dome lights. i have checked my fuses and they are fine. i do not have a second fuse panel that i know of, and am not sure where my circut breakers are, or my inline fuses.
