Gm Trailer Plug. I've tested this on brand new trailers at a dealer, not just on mine and others, so I'm sure it's an issue with my plug. the trailer connector on the truck came from the factory. Yesterday and today, I would get the Service Trailer Brake System, but I don't have a trailer attached.
I have yet to find a trailer where all the lights work properly. Find great deals on eBay for gmc trailer plug and gmc trailer hitch cover. Is there a inline fuse and where or how can I fix it without giving GM a blank check to fix it.
I tested the continuity on plug ok.
Hi, love this new laptop of mine.
