Turn signal wiring and blowing fuse

[mpierce9]

Good afternoon. I have a 1975 Chevy Blazer. When the left turn signal is engaged the fuse blows. The right turn signal works great, zero issues. The left turn signal uses a Yellow wire. I have come to this conclusion because the right turn signal works great and will NOT blow the fuse. The fuse only blows when the left turn switch is used.

I assumed a short directly to ground in the yellow wire but I'v been unable to find one.

Any advice?
