Where is the air conditioner blower located?
The blower fan is located in the inside portion of your air conditioner and is so named because it is responsible for blowing the air to the ductwork in your system which then allows for the distribution of the air throughout your home.
What controls the blower motor speed?
blower motor resistor
The blower motor resistor is responsible for controlling the blower motor speed. In the past, this was done by varying the voltage supplied to the blower motor. In newer applications, the blower motor resistor is actually a solid state module that sends a varied signal to the blower motor.

How does an A / C fan control module work?
An A/C fan control module helps to control the blower that supplies air to the cabin of a vehicle, as well as the cooling fans. The module helps to make sure that the cool air that is produced within the A/C system of a car is blown into the cabin. The A/C fans that are mounted in near the radiator of the car are also controlled by this module.
How does a blower motor controller work on a car?
