I'm puzzled as to why my turn signal does not flash when activated. All the right lights come on (front & rear) when the switch is turned on so there does not appear to be any burned out bulbs and I replaced the flasher unit with a new one. This did not cure the problem. I can use the turn signal, albeit manually by moving the stalk back-and-forth but this is kind of a pain. It just starting doing this about a week ago. What else can I do? Thanks in advance.
