Lost my running lights...

[dataustin]

Guys and gals, I could sure use your help....

Left Austin this morning on my war to Macon, Georgia pulling a 21' trailer. Everything was fine until the sun started to set and I realized I had no rear truck lights or trailer running lights. FYI, the truck and trailer both have blinker and brake lights. BTW, there are no rooms in Slidell, LA so I limped into Diamondhead, MS using my flashers.

Assuming there isn't a fuse involved, would you suspect that I have a short in the trailer harness?

Will the truck lights return to normal after disconnecting the trailer?

 

[dataustin]

No, the rear lights on the truck stay off when I up plug the trailer

so is there a fuse involved? do the front parking lights turn on?

Sounds like a loose fuse.

Any luck resolving this issue?

Sounds like a loose fuse.

Same thing happened to me. Turned out it was a 10 amp fuse blown. Check passenger side fuse box.

Which fuse was it? This just happened to my Raptor today!

So I found the fuse to the rear lights and it was blown. So I replaced it and as soon as I turned on the lights it blew again. Any ideas? Is there some sort of short?

Disconnect the trailer plug and replace the fuse again. If it doesn't blow you'll know it's a trailer wiring issue.
