Hi,
Based on what you indicated, the controller functions but the blower motor doesn't respond. If that is correct, we need to start by checking fuse 10 for power with the key in the run position.
Here is a link you may find helpful:

If that is good and has power to and from it, then I need you to go to the blower motor resister and check if power is present at the black wire with a tan tracer.
If that has power, then locate the black wire on the controller connector and see if it has continuity to ground. It should because the controller is working, but anything is possible.
I attached the OEM wiring schematic below or the circuit. It is a bit difficult to follow, so if you have questions, let me know.
Let me know what you find.
Take care,
Joe
