Left side Flasher/blinker won't turn off

[Maritimes]

Hi there, I'm new at this forum... I have a 2008 CX9. I have been troubleshooting a parasitic battery. After a few attempts and finally getting closer to the problem, I now have the driver side flashers/blinker constantly on, they won't turn off. The front, side mirror and rear amber lights are on. The right side will work fine. I'm running out of ideas. Thinking it may be a bad BCM, but would like someone's option before spend some money in new parts. Any help will be appreciated.
