PART NUMBER INFORMATION
*******************************************************************
The part number is: 27761-70T03 Module Assy-Pow
It is officially called an AC Blower Amplifier.
It cost me $153.32 + tax (not concerned about getting the best price since having the fan on high all the time drove my wife nuts for the two days it was acting up!)
One other suggestion... you're gonna have to take apart the glovebox door and compartment behind it (easy enough). While back there, change out the cabin filter (another Nissan item) since you will have everything apart anyway. Kill two birds with one stone. That thing (if equipped, gets really nasty).

this resistor is located just off from the blower motor on the passenger side, get the new part and then u will see it.

With the sensor replacement it is confirmed that the input signals are not the issue and the fault lies around the main processing of the sensor.
The sensor 's pulses are processed by an OP-AMP inside the dash unit. It is possible that the cluster connections in dash connectors has a fault, a possible dry soldering, bad joint in the circuit of the signal procesing unit.
It is important we need to remove for testing but if a similar pulse can be applied-to the speedo unit , it must work.
This may confirm the issue but you have to decide whether to remove and test the unit or to try for a possible trial replacement from the Nissan repair shop closer to you.
Once confirmed the unit canbe replaced but to make sure that loose joints also are a threat in such intermittent faults, we need to confirm for sure.
I hope this tip help.
