Trailer lights not working?

2005 Silverado 1500. 2wd automatic. Just got a few months back. Trailer lights don't have anything working whatsoever. Tried on 3 trailers I know for a fact had working lights using another truck. I checked owners manual and couldn't find something that tells me what fuse does what. Help! I need to tow often and need my lights working!

I suggest you look in the power box under the hood on the left fender. There is a fuse in there for trailer brakes.

Re: Trailer lights not working?

I looked in there already. There wasn't anything but numbers and a hundred fuses. Nothing that deciphers what fuse goes to what. Can someone help out here?
