Hi,
Based on your description, it does sound as though the body control module is the cause. If you look at pic 1, I highlighted output for the blinkers. What I suggest is to simply check if there is power out from the BCM. Also, check to make sure the ground (pic 2) is in good condition and not damaged or corroded.
Let me know what you find.
Joe
