Hey,

 

I recently bought a 2014 GMC Sierra SLE.  I keep blowing the trailer running light/parking light fuse under the hood.  It is a 20a fuse in location 15.  Any hints or tips on how to diagnose this further would be a big help.  Thank you.

A blown fuse usually means a short to ground.

Blows the fuse with or with out a trailer hooked up?

 

If hooking up trailer blows fuse, trailer wiring has a short.

I no trailer hooked up and blows the fuse, truck has a short.

Fuse is blown without a trailer.  

Then, as diyer2 mentioned, you have a short on the truck, probably in the connector on the truck.
