After much analyzing and trial and error, I still can't get any of the running lights or tail lights to work on my travel trailer when Hooked up to my 2006 Commander.
I do have turn signals and brake lights. I was just told that some Car manufacturers have a separate fuse for running lights,tail lights from the brake and signal lights on the wiring harness. Has any one else encountered such a problem or knows where I need to look ? I'd appreciate any advice.
Thank you,

I've plugged and unplugged ,sprayed wd40 in the socket, checked every bulb,ground wire,etc. and have run out of places to look. Thanks anyway for you reply.

I blew a mini fuse (15 or 20a) under the hood in one of the distribution boxes, and the only thing that was not operable was the trailer lights. You might try there.

I have had the same problem. There is a 10 Amp fuse under the hood that is blown. It is easy enough to find by looking in the manual. Mine repeatedly blows. Has anybody else had a problem? The trailer manufacturer told me it frequently happens if your lights are on when you hook up the trailer, but I have made sure my lights are not on when I hook up the trailer, but it still blows. It never happened with my previous car. I will probably contact the dealer and bring it in.

I had that problem when I first hooked up my friends trailer. I blew a fuse due to faulty lights on the trailer.

I bought some replacement lights for her trailer and was going to put them on but another friend beat me to it!

Check the trailer for broken bulbs or bad grounds as well.

Thanks for everyone's response.
The 10 amp mini fuse was the problem. I replaced it and everything works fine.
I can't believe how much time I wasted thinking it was my trailer wiring.
