What causes a Nissan blower motor to run slower?

The auto AC regulates the fan control amp, which regulates the voltage to the blower motor. A low speed setting causes a lower voltage across the blower motor, which makes the motor operate slower. At maximum fan speed setting, the fan control amp allows nearly all 12v across the motor, which causes the fan to run faster.

What causes a blower fan to not work?

When this happens, you may notice that you will not feel anything blowing out of the vents at all. This may also cause the blower motor to work intermittently. A blower fan is connected to the negative battery terminal (also called ground) on one end and to the positive battery terminal through a blower motor resistor on the other end.

Why is the resistor not working on my blower?
