Turn Signal Problem
 

So I have an issue with my fuse that controls my turn signals and brake lights. It start with when turning on the left hand turn signal the fuse would blow now that I have done some work on it to find the issue when I put a fuse in it blows with out the truck running or anything.

What I have done:

• Checked the light bulbs
• Checked the light bulbs connectors and assemblies
• Disconnected the Trailer assembly
• Taken apart the steering cloumn and checked the switch assembly (this is when the problem got worse)

It is a 2004 F350

Welcome to FTE.

Sounds to me like you have a wire that is chafed and grounding out.
