72 K5 blinker issue

[nebraskasurf]

This might seem ridiculous but I need help figuring out what to do to fix my blinker in my K5. When I turn to the right and turn the blinker on, after the turn, the blinker won’t shut off. I think it’s something inside the column, probably a small plastic part, but can someone direct me on what part it is and How to fix this annoyance?

Thanks in advance.

...and I tried to add a couple pics of my K5 for attention. 😬
