Good morning.It sounds like you may have a defective blower motor resistor.The resistor is located by the blower motor and is what controls power and ground to the blower motor.Please let me know if you need further assistance,Don

Hi Don I cannot accept the answer untill I try the resistor & it is not cheap . I will buy a new resistor and replace it and let you know if it works.because I need to get the blower fan to operate first.

Sorry that the resistor did not solve your problem.Next we need to start checking the wiring.You will need a multimeter for these test.First disconnect the blower motor and check for 12 volts on the white/blue wire.If that is good next check for a ground on the blue/white wire.If that is good next check for a ground on the #1 terminal wire of the resister(where the blue/white wires connects and the harness is disconnected from the resistor).Next check for continuity from the resister on that same wire from the resister to the blower motor.Please let me know what you find and we can go from there,Don
