my turn signals both suddenly went out, but hazards still work, i tried replacing the flasher relay and it did not help. i found that the turn signal fuse was blown so i replaced it, this did not do anything either, any suggestions? It's a 1979 280zx

Currently having the same issue with my 1981 280ZX. 

And still working on it. I'm working under the dash, driver side. 

I had mice in my engine bay but they didn't eat up wires since wire sheathing is not made from vegetable matter. 

This is a current issue so I hope to share with you my findings.
