Left Side Trailer Turn Signal / Brake Light Not Working

[Dwelsh]

So this isn't really urgent but couldn't find anywhere to put it so I'm asking it here.

I've got a 2016 2500 and I had just bought a boat.

The left turn signal and brake light doesn't work.

Go to replace the bulb today and it's fine. Went ahead and changed it anyways. Still no turn signal or brake light.

So I check the voltage and I'm not getting any voltage working my way to the truck.

So both the 7 pin and 4 pin have no voltage on the turn signal pin at the truck.

Checked the fuse under the hood and it is also good.

Aside from tracing wiring. Have any of yall ran into this before?

If so what was the cause?

I do appreciate it.

Check behind the bumper to make sure a wire didn’t get pulled loose or something.

At least for me, almost always it comes down to a ground issue. Great luck.

Did you check pin #6? This is a diagram for my 2014, yours should be the same.

I appreciate the feedback. Im pretty sure its an un serviceable relay. Ive got no voltage at the fuse.
