More than likely this is a body control module issue but we need to track the voltage through the system. So starting at the turn signal wire coming from the power module, we need to see if there is voltage. If not, we need to move to the BCM and check the signal out wiring. More than likely the BCM is not sending the signal for the turn signals.
The way this works is the signal is sent from the BCM but the voltage needed is sent from the power module so we need to find out which the issue is and more then likely it is a BCM.
Here is a guide that will help with this:

Let me know what questions you have with this and we can go from there. Thanks
