7 pin and 4 pin trailer connector - No right turn, Clyde

[MobileMatt]

My 2017 Sierra 1500 has had an issue with no Right turn signal or brake light on trailers.  This is on both the 7 pin and the 4 pin connectors on different boat and utility trailers. Running lights are fine on both sides of the trailer. I would really like to have the Right side working as it's the most important signal in my opinion.  When I need to slow down and get to the right, that's when it counts in towing.

 

I put the voltmeter on both the 7 pin and the 4 pin connectors and there is no voltage on the Right (green to trailer) contacts.  My thought is to change out the 7/4 connector on the truck with a new one and see if that remedies the problem.  Has anyone else had this or a similar issue? What connector did you go with? OEM or aftermarket like Curt, Reese, etc? 

 

Thanks!

I am guessing you checked all the simple things first like Fuse #17 for the right trailer stop/turn lamps in the Engine Compartment Fuse Block?

Doh! Heat must be getting to me. Yeah, fuse #17 was blown. 

Thank you Mr Weller. I appreciate your post and the reminder. Saved me some $ and I owe you a frosty beverage.
