Power the blower motor direct from the battery and see what happens

You can power it directly and nothing will happen. It relies on a digital speed signal from the A/C programmer, that comes in on the little gray wire. More than likely, you need a blower motor. Very seldom, in fact never, have I seen a failed programmer cause a lack of blower operation. Check that you do have power and ground at the blower, with a test light across the connectors large wires(red/black). If you have a light across that circuit, replace the blower motor.

Try to direct wire the motor if no check the voltage to the motor if none. Youll need to remove the blower motor wire it goes to a module in the a/c case replace that blower module.
