HELP ! - Dash Lights and Trailer Running Lights out!

[feetwet]

My trailer running lights and my dashboard illumination lights went out last night when towing.. I can't find any bad fuses.. need help troubleshooting.

The interior (i.e. dome) lights still work but I can't see the speedometer at night since it has gone "dark".

Hazard lights still light up the trailer lights.

I think I've checked all of the fuses and all seem ok so far.

Look for a bad ground!
It's been my experience that most electrical problems come from bad grounding.

It's still (barely) under warranty.. I'll take it in if it's not a fuse type fix.

I probably wouldnt tell them you had a trailer hooked up at the time. They will look for any reason to say its your fault.

Just say the dash lights dont work anymore.

Well, if it's still under warranty and qualifies and it's a factory installed trailer wiring kit, you don't really have anything to worry about!
On the other hand, if a second party installed the trailer wiring kit, you will have to take your truck back to the company that installed it for you. Then, let them sort it out and make sure you get everything in writing to cover your ass.
If, you installed the trailer wiring kit, then go over the wiring install with a fine tooth comb and see if you can find the problem.

It's a factory tow package.

Let the stealership sort it out for you!
Gotta love warranty for just this reason!
