sounds like almost the same thing that i got (3.5 also), my dash lights went out along with my tail lights that blink when i arm and dis-arm my car, i checked my fueses and my tail fuses is blown! (is this the same problem you are having, or did i read you post wrong?)
then i replaced the fuse and it instantly blew when i turned my car on, so apparently there is a short somewhere

(most likely something to do with my stereo and my speakers that i installed).
so here's what i did..since i cant see my gauges when driving at night i went to radio shack and bought one of those cig lighter lamp thingys (looks like a minature snake lamp, except it plugs into your cig lighter) and i put it in my lighter and pointed the snake right at my dash

, i like it so i think i might keep it that way for awhile, very unique and original i think
