Trailer Running Lights

[Juan Grande]

So the brake lights and turn signals on my boat trailer work fine, but the running lights don't work. I hooked up a different trailer to my truck and the running lights didn't work on that either. 

I got a test light and tested all the pins on the truck socket and pin socket next to the ground does not have juice (I believe that is the brown running light wire socket).  I tried a new 4 pin converter and that same socket is dead.  I pulled the trailer fuses in my truck fuse panel and none of them look like they're blown. I have a 2013 Chevy Traverse and I think it should be the trailer parking lamp fuse, but it looks fine.  Just wondering if anyone else has any suggestions?

Thanks in advance!

is there a fuse box under the hood? My older silverado has separate fuses under the hood for the trailer lights.

Yep, fuse box under the hood. There's about 6 different fuses for the trailer, but none of them are blown.

Try pulling each of the trailer fuses and replacing with a new one. Sometimes they aren't seated all the way or it's blown but hard to tell.

After the fuses, crawl under in back to inspect the wiring going into the connector on the truck.  If you have one, a test light works good for probing the wire to determine where it goes from hot to not.

I just paid $100 shop bill because the fuse I inspected and passed for good was blown . Couldn't see the break but mechanic did a  check with a continuity tester and sure enough it was blown .

Thanks for the tips guys, I'll try replacing all the fuses.

If that does not work, possibly look through my dilema of having a single trailer brake light not work when hooked up to my Trailblazer. Was a simple fix, but hard to track down.
