I would get at the blower motor connector, when the problem is ongoing. Key on, HVAC turn on, I would check for voltage and ground at the connector. If no voltage, I would backtrack the circuit. Purple wire is voltage, black wire is ground. The voltage circuit comes from the resistor assembly. I cannot say the resistor assembly is faulty, I would have to check feed to and from that assembly. There is probably a blower fuse in under hood fuse box, that fuse circuit is hot all the time, use a test lite. Also, HVAC fuse left instrument panel fuse box, it goes hot when you turn on the key, again use a test light on the circuit.
