i am assuming you have checked the bulbs first. then check to see if power is coming to socket and check ground as well. if no power have a pro scan for codes on turn signal module

I would check the fuse on the under-hood fuse panel which controls the lighting system. Here is a guide to help and the fuse locations in the images below:

Have the lighting system on before you check the fuses for power. Check out the images (below). Please let us know what happens.
