No trailer brakes

[Delta506]

Hello everyone
I have a 2015 F350 and l'm having problems with the trailer brakes system.
I have no power at the trailer 7 pin connection. Everything else works fine just no trailer brakes.
Any ideas

Look in the Owners manual for a fuse or other protection device (fuse link?). That is all I have got...

I don't have that new of a truck, but on many older Fords, equipped with a factory towing package, a relay would have to be installed in the power distribution box for the brake controller and the charge line to have power. Not sure on the newer trucks.....

I would think the relay is there. I borrowed a buddies trailer and the trailer brakes worked awesome. As DaveBen said I'd look for a blown fuse or something.

Or maybe the factory forgot to put the relay in. I just read where a guy pulled his intake and one of the knock sensors was never plugged in from the factory.

Check your owners manual for the trailer brake fuses, then the relay.

Also check the connector on the drivers side under the rear of the truck. The 7 way branches off the main circuit at that point.
