Trailer Running Lights not working 2019 F-250
I just purchased 2019 F-250 and the trailer running lights will only work when
the truck headlights are on the "on" position. If I switch to automatic
headlights the trailer running lights do no work. Turn signals, trailer brakes and
brake lights work great when headlights is in the on position. How do I get the
trailer running lights to work when the automatic headlights is selected?
