Hello,

I would start by checking all system fuses. Here is a guide to help with the blinker and turn signal wiring diagrams below so you can see how the system works and which fuses to check. Also I have included the fuse panels and locations below. Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.

The blinkers do not work. The hazards work except for the right front. When the hazards are on, only the left arrow is on in the dash. I have checked the fuses& they seem to be ok. Any help is appreciated, thanks.
