Have you attempted any other repairs? Is it the rear turn signal that is not lighting?

No left signals or left flasher Works intermittently Trailer connections were corroded so were disconnected no change. Leaning towards multi function switch?

Are you thinking
Customer: replied 2 years ago.
Most of the time when I get it blinking it quits when I put it in the lock position. Thinking it's the switch
Expert:  Dave Nova replied 2 years ago.
Sorry for the delayed response. Most of the time the problem is a bad ground connection at the rear taillight connector. Remove the left rear taillight and disconnect the electrical connector. Look for discolored terminals or even melted plastic on the connector body. Let me know what you find.
