I think the voltage regulator inside your alternator went, sent an overdose of volts to your fuse box and blew them out. have your alt. tested if you think it is a possibility. Do you have a volt meter on the dash, or a dummy batt. light? And if so, are either acting up? or do your headlights grow brighter if you rev the engine? Let me know.
