I have a '97 F150 4x4. I pull a small trailer with just the 4 wire hook up. It blew the fuse under the hood (I still had brake and signal lights). I replaced the 5 amp fuse and I still don't have any lights. Does anyone know if there is any relays or other fuses. Thanks for your help. JohnE

 

Hi JohnE Welcome!

Look carefully around/behind the fuse box-drivers side? (under hood)
There maybe another small fuse holder..it might be covered with tape..so look closely.

Good luck...OT

 

Thanks for the reply Oldtimer. I did look again and found that I should have looked closer (just like you said). I had already found the little fuse block that is just for the trailer (that is where the 5 amp fuse is) I then looked at the manual again and it pointed to a 20 amp fuse in the bigger fuse box that was for trailer lights and stuff. It was blown! Now my lights work fine. I should have known, I guess. Thanks again.
