New 2010 E-150 passenger, New 2010 Haulmark cargo trailer, no running lights!
I'm the proud new owner of a nice rig, 2010 E150 passenger van, loaded, and 2010 Haulmark 6x12 cargo trailer. Suddenly there's no running lights. Brake lights/turn signal/4-way flasher all work fine.
I've tried an adapter and plugged my flat connector into the 6pt. round connector but the same problem exists.
I am clueless which fuse may be responsible. Anyone have an idea what fuse I can check/replace? Assuming that's the prob.
