What does a fan module do?
A cooling fan module helps to maintain a constant supply of fresh air into the cabin of a car by controlling the blower that supplies the air. When cool air is produced in the car’s A/C system, the cooling fan module blows it into the car maintaining a fresh supply of air even when the windows are all rolled up.
Why do I need an AC fan control module?
3. Weakened air flow 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.
How do you remove a fan control module?
Unplug the connectors and set them close but out of the way. Step 4: Removing the Fan control module. Once the electrical connectors are disconnected we can now unbolt the unit. Typically only a few bolts hold the control module in place on the fan assembly. Remove these bolts and place them in a safe location. They will be reused in a moment.
Can a bad fan control module cause damage?
Usually, you will have a variety of signs that the A/C fan control module is going out. If the cooling fans begin to run erratically, then you may have a problem with the control module. Letting this type of issue linger can lead to a number of issues that can cause damage to your car.
What do you need to know about fan control software?
As the name suggests, a fan controller software is what can be employed if you wish to be in control of the speed of your PC fan. It manages the rotational speed of the electric fan. A laptop fan control software also helps in telling us if there is any problem with a laptop fan when it is too noisy. We now know what makes a system turn on its fan.
Is the fan control module part of the AC Control System?
The fan control module is part of the AC control system. It is used to tell the AC condenser fan when to turn on and in some cases the same unit is used for the radiator fan as well. Though uncommon the AC fan control module can fail over time.

How is the electric fan controlled by the PCM?
Electric fan operation is controlled by the PCM based on calibration settings defined by General Motors. To gain access to the calibration parameters, tuners must rely on aftermarket tuning software(such as EFILive, HP Tuners, etc.) to expose the electric fan settings and make desired changes.
How is the temperature of an engine cooling fan controlled?
This air flow removes heat from the coolant created by the engine using the radiator as a conductor. An engine cooling fan is temperature controlled to only run when needed. All engines have a preferred operating temperature and need to warm up to operate at peak efficiency.
