Turn signal issues
 

Hello, I have a question I have a 07' Chevy suburban. and I have turn signal issues. I turn on the turn signal on the right side and it works fine, But when I use the left side it goes on and stays on with no blinking. The clicking noise is really fast only on the left side, somewhere under the dash.
So I replaced the turn signal switch, and that did not change anything, I also replaced all the fuses that were related to the turn signals.
I have run out of ideas. Please help me if you can.
oh, yeah all the light bulbs were changed also on that side to front and back.
I am fresh out of ideas.
Thank you.

Welcome to the forum.

Welcome from Florida. Did you check the sockets for the bulb to make sure they are making good contact with the bulb?

I did forget to mention, I replaced the light harnesses front and back. And thank you
