Left turn signal light issue.
My 2007 2500 express has suddenly developed a problem with the left turn signal. I replaced the turn signal assembly, Cleaned the circular copper contact ring on the column but the issue still remains. The light will blink sometimes but other times there is nothing I can do to make it blink.

There are a lot of places were that failure could happen. I would troubleshoot the bulb and connector first. Ensure all of that is good because it is exposed to the elements and greater/faster temperature swings.
