Default electrical problems

My heater (A/C) blower, headlights, turnsignals, and wipers all suddenly stopped working today. I've checked all the fuses associated with those systems, but the fact that they all stopped working at the same time makes me think it's something else. Is there one relay that could be affecting all those things? My evening plans have been dampened by the lack of headlights. Thanks!

Cool, thanks. Is there a good relay diagram anywhere online? How would the ignition switch affect it? Everything else is fine, and the car starts/runs OK, wouldn't the ignition switch going out kill the whole car?

Sounds like the Load Reduction relay is the problem, unfortunately I can't find any way to buy one in the Seattle area before Monday, which !@#$%! sucks.

Anyone have a space laying around?
