I keep blowing the Right trailer blinker and brake light fuse in the truck.

Any ideas what may be happening?

Exposed wire on the trailer causing the problem?

Short in the system, had the same problem a few years back. My short was in the truck wiring harness.

A hot wire is grounding itself out somewhere and shorting. Only way that you can blow fuses.

Probably right that it is an exposed wire touching the metal on trailer somewhere.

I had the same problem a couple years ago and it was an exposed wire inside the trailer frame. I would replace the fuse and everything would be fine until I started driving and the wire would touch metal and blow the fuse again. I ended up tearing out the wiring on that side and replaced it. It has worked great ever since.
