I know this is for trucks but maybe someone can help ? my girl friends dad has a astro van and half of electric stuff quit working I have replaced all the fuses in the box and I still cant get the headlights , taillights , horn , radio, and all inside lights to work. this is what does work heater a/c , dashlights ,powerseats,and turn signals. Its like 1/2 the stuff works and 1/2 dont . he said it all worked untill yesterday. also the only bad fuse was the radio. Is there a ground problem or other fuses hidden somewhere.
