How to fix front signal lights? 2012 Kia Rondo

What is your question?

The year of the vehicle is actually a 2012. The front signal lights seem to be moody. Every so often one of the front signal lights will not turn on. But the other one will work. About 1-2 hours later it will be working again. It juggles between the left and right signal lights. The bulbs are not burnt out, they are new bulbs. Is there an exposed wire that I should be looking for?
