Interior trailer lights don't work
I just bought an enclosed trailer, all the exterior lights work fine, but the interior lights in the trailer don't work. I asked the trailer place and they told me GM doesn't supply the auxiliary power fuse standard. So I looked in the fuse box under the hood, and there is a live fuse in the spot marked auxiliary power.
I drive a 2003 Silverado with the towing package and my wiring harness on the truck was factory installed too.
With all the trailers out there, I can't believe my problem is new. Any suggestions would be appreciated.
