I may be slightly off, but I have noticed the 'click' for the flasher is coming from the hazzard flasher button. I have removed the harness and found the turn signals do not work as long as the switch is disconnected. Hope this helps!! Just replaced mine. The Emergency Flasher switch (button) on the dashboard serves as the turn signal flasher also. Around a $35.00 item. You have to disassemble the face of the dashboard.. relatively easy, about 45 minutes.
Turn signal flasher is part of the hazard warning module and replaced as a unit
