We have a 2004 39W Journey ...
the right turn signal on my toad quit working over the weekend. There was no signal at the 7 pin connector. So I knew the loss of power was ahead of that.
There have been two threads on this bulletin board that were extremely helpful in finding the fuses.
Vicsyrd thread
Rvarner Thread
By reading and re-reading those threads I was able to locate and replace the blown fuse.
While I had things torn apart I took some pictures ... I hope these pictures will help the next person that needs to replace trailer connection fuses ...
The cover to the fuse box snaps open and swings up then lifts off
I chose to unplug two cables to make it easier to access the fuse box ...
Here is a close up of the fuses
