Thanks for the response. I located the panel with the plug in modules and dozens of fuses. I bought a flasher supposedly for my car, but it is not identical (different number of prongs). I think I will try the Hundai dealer and look at their flasher unit.
Where exactly is the signal flasher, what number?
