Hi,
First, check fuse 4 to make sure it is good. See pics below.
If the fuse is good and has power, then I need you to the blower motor and check the red wire for power. It should be present at all times. If there is power, check the black wire in the connector for continuity to ground. Also, at the controller will be a black wire with a white tracer. Check it for ground as well. Here is a link you may find helpful:

Let me know what you find. Keep in mind, there should be power at all times at the motor itself. A ground path is provided by the controller to complete the circuit.
Simply based on what you described, I have a feeling it is the controller that has failed, but we need to test first.
Let me know.
Joe
See pics below. The last two pics show the right maxi fuse box location and fuse.
