Is the bulb in the left turn signal exactly the same as the one on the right? Have you tried replacing them even if it is? Do you have seperate flashers for the left and right hand side? if so are they identical or have you swapped with each other to see if the problem follows the flasher? If you suspect the column unit change the wire so the left is coming from the RH wire and the right is coming from the LH wire. If it's the column unit the problem will now be on the RH bulb. If not then the column unit is fine.
