The turn signals were not working, then they were working. But now that I need to get an engine check, to register my car, they no longer work.

I didn't think it was the fuse but I went ahead and replaced it anyway and the problem persists. I see some old posts about this, I was hoping for some newer information.

What's the next step to figure this out without taking it to a shop? It seems I need to remove the fuse box relay module, but then what?

thanks!!!
