trailer light problem
Tthe running lights on my trailer work, but no brake or turn lights. Turn and brake lights work fine on the truck. Checked with a meter at the connector, so I know it is not my trailer. I found this info in a search, but the fuse is good. Does it go to a relay or another fuse anywhere?
"This info is from a 2003 superduty diagram, so I hope it's the same.
The left and right turn come from fuse #6, 20 amp in the underdash fuse box. "
Where else can I look? any suggestions?
