I have the car listed above SES. Back work fine, running lights work fine, front and back. Just no front blinkers. I have checked the fuses, changed out the multi-function switch, changed the front bulbs, checked for power in the front and it is getting none. I need help. Is there a relay or something that I haven't checked yet? Advanced auto parts has a multi-function relay. But I can't find where it would be located on the car to change. Any help at this point would be appreciated. Thank you for your time and efforts in advance.

Your turn signals are controlled by the smart junction box FET transistors that will shut power down on the turn signal circuits if there is a circuit fault detected. One way to reset this is to either disconnect the battery for 5 minutes or disconnect the smart junction box connectors for 5 minutes. If you have a scan tool that has the capability of retrieving codes from the smart junction box I would do that first and use the clear code or keep alive memory function that way. I've attached the wire diagrams for these circuits so you can see what I'm talking about, no external relays because it's integrated in this module. As crazy as it sounds, I've fixed lots of crazy electrical issues by disconnecting and reconnecting this module.
