Juan Grande Posted April 29, 2016 Share Posted April 29, 2016 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!

sunniewally Posted April 29, 2016 Share Posted April 29, 2016 is there a fuse box under the hood? My older silverado has separate fuses under the hood for the trailer lights. Quote Link to comment Share on other sites More sharing options...
Juan Grande Posted May 2, 2016 Author Share Posted May 2, 2016 Yep, fuse box under the hood. There's about 6 different fuses for the trailer, but none of them are blown. Quote Link to comment Share on other sites More sharing options...
SkunkedAgain Posted May 2, 2016 Share Posted May 2, 2016 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. Quote Link to comment Share on other sites More sharing options...
Hoey Posted May 2, 2016 Share Posted May 2, 2016 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. Quote Link to comment Share on other sites More sharing options...
Cheers Posted May 3, 2016 Share Posted May 3, 2016 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 . Quote Link to comment Share on other sites More sharing options...
Juan Grande Posted May 3, 2016 Author Share Posted May 3, 2016 Thanks for the tips guys, I'll try replacing all the fuses. Quote Link to comment Share on other sites More sharing options...
BoxMN Posted May 3, 2016 Share Posted May 3, 2016 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. Quote Link to comment Share on other sites More sharing options...
