Heater is not producing heat at all. No power is getting to the blower motor.

Good afternoon,

I attached a wiring diagram for you to view. I highlighted the wire that is power to the blower resistor that feeds the blower motor. Verify power on both sides of the fuse with a test light or voltmeter. This is not a visual test, it is a voltage test.

The blower motor location is attached and the resistor is right next to the motor.

Did you check the red wire at the blower resistor? That is where the power starts and goes to the blower motor.
