View Full Version : trailer light question

03-29-2009, 07:47 PM
I have a 2003 F-250 I recently purchased a 7 X 16 open landscape trailer. When I turn my truck headlights on my trailer lights come on, but when I put my truck signal lights on my trailer signals do not work. I am sure it is something easy, but never the less I don't know why. So any help would be appreciated.....

Check the trailer turn fuses.
They are under the hood or under the dash.
The truck and trailer have different fuses.
You will need your book, because Ford doesn't make the fuse box.

Yes the truck may have different fuses for the truck lights and a different set for the trailer circuits. It could also be as simple as a bad ground wire too.
