All turn signals stopped working

Okay I have been searching google for a while now and can’t figure this out. Hoping for some help. I have a 2017 SR Utility. Stock bulbs all around externally. The only modification to my lighting is the three grill lights that I wired into my drivers side running light so they come on when I turn my DRL on. I have had occasional issues with a turn signal flashing quickly but it went away (happened to both left and right but the other lights always worked). I got in my truck yesterday and all turn signals are not working (front, rear, both sides). All other lights are operational. When I turn on my signal at the stalk I get a fast flash on the dash but no lights on the exterior. When I turn on my hazards I get a normal flash on the dash but no lights on the exterior. From what I’ve seen this model does not have an independent flasher relay (this was my first guess at the issue). Has anyone else dealt with this or found a solution? I’d prefer to fix it myself if I can, I’m fairly mechanically inclined and don’t mind digging into issues but I’m no electrical guru. I saw one thread of someone wiring in a 2nd gen flasher into the all-in-one unit behind the dash but I don’t know if that’s the fix or not. I’d appreciate any sort of insight as to where to begin. Thanks!

 

Check fuses. maybe disconnect the grille lights you installed.

 

Hi Maybe start by pulling a bulb and checking for juice. Very odd for all the bulbs to go out but for me - that would be a start point. Also check the ground.

 

Each lamp on the turn signal circuit has it's own ground. No function means no juice. If 15A HAZ fuse is gone you wouldn't get an indication in the dash.
I fear the turn signal module is a crispy one.

 

Thank you for this. I will check there and start working to see what I can figure out. Just hoping to not have to take it into a stealership.

 

I also thought it was weird that they all went out at the same time. It’s why it got me thinking of a flasher relay or some other component issue outside of a bulb issue.

 

I always go to the end of the run and check my + & -. Then I work back. I'm for sure no expert, but it has helped me many times. We all have our own starting points when it comes to electrical issues. These guys will steer you right. Hang in there and the answer will appear. Regards Scott

 

Verify intermittent power when HAZARDS is selected...

 

Did you ever get this problem solved I am putting my truck in the shop because I’ve tried everything
