This is a little misleading on these vehicles because there is a flasher/relay, but it is internal to the smart junction box.

I am attaching the wiring diagram below that shows the SJB has a control box which is the actual relay. They are not replaceable separately and you have to replace the SJB to replace it.

However, I am also attaching the testing that you need to run through in order to figure out what the issue is.

Please see the info below and let me know what questions you have on this.

Thanks

I would check all of the fuses because the flasher module is integrated into the smart junction box, but a bad fuse will cause the system not to work. Here are the turn signal wiring diagrams and fuse panel locations and diagrams so you can see how the system works and which fuses to test for power. This guide will help you get started:

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
