Good morning,

Try disconnecting the turn signal switch connector at the bottom of the steering column and see if the fuse still fails.

if it does, then it is a wiring harness issue.

if it does not, the the switch or wiring is bad in the column.

I attached a diagram of the fuse, which I think is the one you are referring to, and what it controls.
