1966 dart convertible

well, brakes are up and running, roll control is installed, center console, check!!! Got it registered and ordered tags this morning, all that's left is install the front seats......and.....stupid left front directional is being a D#%K!!! Right directional, front and rear are fine, left rear is fine. Left front doesn't operate unless I wiggle/put a little pressure on the lever? Then it comes on. I'd like to think something is loose in the turn signal switch that can be repaired before I spend $159.00 on a new one. Question is, how do I get it out from the column? Nothing in the manual, I've searched the electrical forum (thought that would be a big topic in there). Steering wheel is off but I cant get the plastic piece out??? PITA!!!
Help is appreciated.
