GEN 1 Drivers side turn signal not working

[That1stGenRaptor]

On my 2011 Gen 1 my drivers side turn signal Isn't working. The park lights still work it just won't flash. I put the stock bulb back in to see if it was just my Leds, and same thing still didn't work. The Mirror light and Tailight still blink. All signals Hyperblink because of this issue. I would appreciate any help available.

Did you check the fuses?

My Truck started doing the same thing on the passenger side. I have changed out the LED bulbs back to OEM bulbs with no luck. I have checked the fuses all appear to be good. I'm not sure what is going on either.

Yes, checked the fuses they seemed to be good. My thing is you can hear the clicking of the fuse, so ik that works. And I checked the interior fuse box yet it was also fine. The bulb doesn't flash all though it stays lit. So to me it has to be something between the fuse box and the wiring harness. My wiring guy is going to look at it tomorrow.

My first guess: a dirty ground wire somewhere. It's a time suck to find stuff like this.

Just looked into it, there's a break between either the turn signal to the fuse box on the engine bay or it could be as deep as somewhere in the steering column. It's not the interior fuse panel as it was getting power to it. But we pulled
out fuse 4 and it was burnt out, now the dash lights nor the exterior lights even come on and the truck won't crank when the dash lights do come on there's a bunch of codes. Also the sidemarkers started blinking. Going to have to take it to someone who has the patience and want to mess with it, and it's going to take a lot of time and money. It's gotten beyond me.
