Get at the blower motor wiring connector. With hvac turned on, check for voltage and ground at the wiring connector. If good voltage and ground with no blower action, suspect the blower motor.

To add, terminal A at the blower connector is voltage. Terminal B is ground. You can use a testlite between those two terminals, key on, hvac on, If the light comes on bright, you have good voltage and ground.
