There could be a few things contributing to this. One is if the pins and sockets on the connection are in the right place (not pushed in somehow, if it's rusty, if it needs more pins). More than likely you won't have to follow the wires to see if there is one exposed since all markers don't work, but i would start with the connections first, try to clean then up and make sure they are in the right place. The other factor would be that the wiring harness may just be bad for the wires on the markers. I hope this helps you out and if it doesn't i will happily look more into it.

    I have rewired the entire trailer and replaced all of the lights with new.The lights did work last year but after driving for awhile the fuse would blow under the dash in the fuse panel.I have power to all the lights on the trailer except the marker lights.I have tried to plug in my other trailer but I get the same results.This leads me to believe it is the truck.

When i hook my trailor's lights to my 2003 yukon xl, park lights doesnt work, but all other lights work


You mean the truck parking lights dont work, or the trailer running lights dont work? Does the trailer just have tail lights or does it have front and rear side markers? I think you mean the trailer lights. Check for power at the plug,(Brown Wire) if there is power, then you could have wiring problems, but a better description of what works and what doesnt work needs defining.

2005 Chevy Tahoe Trailer Running Lights Out


Depending on what type of trailer you have, a blown lightbulb on one marker could kill them all (like the old Christmas light strings). Look at those, and make sure your ground is good.
