I have a 2012 SuperCrew Lariat. When hooking up my boat trailer I noticed that my running lights weren't working. My brake and turn signals work along with my hazards. Thinking it may be the boats lighting I hooked up my utility trailer same problem. I'm assuming it's a fuse blown somewher but can't seem to locate which one.

Can anyone help out me figure out which fuse it is. I'm supposed to leave in the morning for a trip.

thanks

there is a 20 amp fuse under the hood on my 2010 that has blown a couple times and I'm pretty sure it caused the same problem for me, don't know which one specifically, but it's located fairly centrally in the fuse box.

I had this same problem once. I can't remember which fuse it was or even if it was under the hood in that fuse panel or in the passenger kick panel. I found my answer in the owner's manual.

I've looked at the fuses under the hood and in the fuse box on the passenger side. I can't seem to figure out which fuse it might be. All the ones under the hood look good. I pulled fuse #10 and #31 and they all looked good.

Any help is appreciated.

Thanks

x2 on the under hood fuse. Mine’s a 2009, but I blew the brake/signal fuse for the trailer. I think it was #45 or so, like that’s any help to you.

And check your connection. For my last trip, my right brake/signal wasn’t working and it turned out to be a dirty connection on my 7-pin. If you have a voltmeter, give that a try.

Check fuse 66,67 under the hood.

I've used a volmeter on the four pin connection on the truck and it's not regesitering anything. So I'm sure it's a fuse somewhere. I did look at fuse 67 under the hood and it seemed to look good. I'll try 66 as well.

On my 2010 I had the same problem. It was fuse 31.

The good fuses get you every time. I had to leave my trailer an hour from my house because I couldn't get the parking lights on didn't realize there were so many fuses to check. That and it was dark and 10 degrees outside. But yes there was one under the hood that was blown.

Just wanted to follow up for anyone who may have this issue in the future.

It was fuse #67 under the hood (20amp). Although we checked that fuse that night we couldn't tell it was blown using a flashlight or garage lighting. Once I took the fuse out in the day light you could barely see wher the fuse had been blown. Replaced the fuse and everything worked fine.
