Hey All,

I have a 2003 F250 SD 7.3L.

I am having problems with my trailer lights.

I have brake lights and turn signals, but no running lights.

Unfortunately I do not have the owner's manual as I purchased the truck used.


Can anyone tell me what fuses are used for the trailer running lights, and where they are located?


Thanks in advance!

 

Download an owner's manual from www.fleet.ford.com under Maintenance

Thanks for the post.

I looked in the interior fuse panel box last night. I found a 20a fuse blown but did not know what it went to since I didn't have a manual. After looking at the downloaded manual I see it is a fuse for the Trailer tow park lamps. I imagine replacing the fuse will fix the problem (assuming I don't have a short somewhere).

I appreciate the help!
