Trailer signal lights not working

nick956 · August 19, 2015

K, so the GREEN wire on the plug for 7-way doesnt have power for the trailer turn signals nor brakes. I serached and searched and followed the info given but to no avail. I already checked all fuses for the trailer lights under the hood and driver dash panel. Also checked hazard/flash (LCM) module with another and still no power. The only thing left is to follow wire into whereever it leads. Am I missing something?

Year and model would help you get a better answer as there is a difference between some years prior to 2007 NNBS.

I got it, it was the pin where it plugs into fuse box and I guess isnt making connection so I just cut a piece of wire and stripped both ends then stuffed in one end into where the TRL TURN/STOP fuse plugs into the box and then spliced into the GREEN solo wire behind fuse box and tada power to the trailer turn signals pin at rear.

( basically I bypassed the fuse box and ran a wire around it. So for those that have similar issues and find out that it wasnt fuses nor the flasher/hazard relay under dash then try this and hopefully it will work for you like it did for me.
