Hi,
Have you checked fuses yet? If not, let's start there. I attached three pics below. The first two are the wiring schematic for the blower motor. Pic 3 shows what fuses I need you to check in the fuse panel inside the vehicle.
When you check these fuses, it is also important to confirm there is power to them. These fuses will only have power when the key is on, and the blower motor is requested on.
Here is a link that shows how to test the fuses for power:

Let me know what you find.
