My trailer lights shorted out over the weekend, and after i switched out the burnt fuse I still do not have power restored to the left turn signal and brake lights. Any ideas what to do next?

 

Is this on the factory 4 pin or 7 pin trailer tow adapter ?
- It isn't an add on to the truck's wiring..

What fuse did you replace ?

 

I had a similar problem to my trailer. My problem was I had turn signals and no clearance lights. My was a simple burn't out fuse. I bet its another fuse burnt out. Once day light out I'll check my owners manual and I'll post the fuses I replaced. Or you can go into your owners manual and look up fuse locations for turn signal and trailer running lights. I think both are 20 amp fuses.
