Hello, my name is***** usually means the blower motor transistor has failed. Monitor the Orange/Black wire for a voltage signal from the heater control unit-panel to the base of the blower power transistor and look for a voltage signal using a digital volt ohm meter. If there is no signal, power up an old style test light and remove the Orange/Black wire from the blower power transistor. Then with the key on, touch the test light to the terminal of the power transistor that the Orange/Black wire was connected. If the power transistor is OK, the blower motor should work.Let me know how it goes or if you have more questions. Thanks.
Is blower motor getting good power on? If so, does orange/black wire at transistor get signal?
