Electrical is gone

alot of times, the dash lights just burn out. and since they're somewhat difficult to access without dropping the column, people would often just accept that the ol' dart didn't have dash lights and it would get driven that way for a while. so while you've got it apart you could try changing a few and see what happens. sometimes the board's just dirty. as for the turn signals, maybe the turn signal cam? something not making contact? i've seen some broken ones on the manual signals that would work when in just the right position.
