Running lights not working.

[RobWilson]

Have a 2016 forest rover forester 3171ds on a ford e450 chassis. Running lights were blowing fuses amd I would replace and the lights work till fuse would blow again. When working all lights worked, now fuse is holding but no running lights. Any advice on how to resolve this issue?

Perhaps the Ground wire connection for the running lights is broken or corroded. This connection could be in the front-tongue or rear-bumper area or the trailer frame.
