The trailer tail lights and trailer running lights are not working on my 2008 Lincoln Mark LT, which I think is the same as the F150. I have the factory towing package. My owners manual list fuses for the left and right trailer turning/brake lights. However I didn't see mention of the fuse number for the trailer tail/running lights. Does anyone know the number in the fuse box for this fuse. The trailer dealer said it was the truck that was the problem and probably a blown fuse.

 

I checked mine a couple of weeks ago, but I can't remember the number for sure. I think it was 10 or 11.

 

When you pull the cover off the fuse box there is a listing of all the fuses in the inside cover.

 

I went and looked when I got home, it is #10 on mine.

 

Thanks guys. It was also #10 on my Mark LT as well. A 20 amp fuse and it was blown. Now I hope it was just an oddity that it blew and there isn't a short. I will check when I pick-up my trailer at the dealer.
