I'm sure that I'll sound stupid for not being able to figure this out but here goes. I apparently shorted out my running lights on one of my trailers and blew a fuse on my truck but can't figure out which fuse it is. I've gone thru the owner's manual looking for the fuse, couldn't find it and have even pulled every fuse that I can find with no luck. I've looked under the hood/driver's side in the fuse box and also passenger side interior kick panel. Is there something I'm missing? Could it be a relay?

Oh, this is on a 2008 F-250 diesel.

Thanks for any help.

 

so no matter what trailers hooked up the lights dont work on any?

 

No matter what trailer is hooked up there are no running lights, just brakes and blinkers. I've had the problem before on other year F-250's and it was just a fuse. I can't find the problem here.

 

well, all i can say then is check the ground wire and make sure all the wires are hooked up. also make sure the connection is clean. im also assuming that you checked all the fuses related to the lights.


good luck
