This vehicle does not use a traditional hazard/turn signal flasher. This function is controlled by the Body Control Module (BCM).
There is no flasher as in the old days.
The BCM controls the speed of both 4 way and turn. It may have been damaged from the short circuit issue.
I attached a picture of the location and the procedure for you. It is a programmed module.
