1991 headlamp problem...they stopped working

I walked out to my car about a week ago and started and drove my car. When I got to the bottom of my hill i noticed that i had no dash lights. Next i started getting flashed by other people trying to tell me to turn on my headlights. Thats the end of the problem. I had no headlamps. Just one day earlier I had headlamps and no snow. The day the lights went out i had snow. I wondered if that would really affect anything. I havent driven the 91 gp since. I am starting to miss it. I read thru the not-so-overly helpful manual which said if sudden headlamp failure happens, to take it into a shop for wire diagnostic work. I feel I am a good enough mechanic if I know where the problem is and can get to it, I can fix it. One of my friends suggested its in the collumn would this be true. I dont have a chiltons for it so I dont know where to look. Help please

Maybe you have a short in the headlights circuit and that blew the fuse. Scatterpack may be right, too.

whats a scatterpack?
