All my lights work except my running lights when I turn headlights on. Turn/brake alll work fine. Is there a fuse for just runnig lights or is it the wiring? 02 chev. 3/4 ton.

My 03 has a seperate fuse panel box under the hood right in front of the driver. Get the maunal out but the fuses to the trailer are in that black box.

i agree w/ 500hps


if your tow rig came with the tow package, you probably have a seperate fuse for running lights. happened to me, pinched a wire in the drive guard. 04 ford f250

That was it, Thanks
