My turn signal lights just died on me. (not the light bulbs themselves) When I turn on the turn signal switch in either position, it doesn't actuate the turn signal. I've replaced the fuse and even put back in the old honda relay (don't ask, bought the car with a turn signal speeder, never took it out). Still no go. 99 Civic ex, no electrical mods, nothing else seems to be affected either. Any suggestions?
