What is the AC Fan Control Module all about?

Depending on the make and model you drive, the AC fan control module may be located on the firewall under the hood, or somewhere else in the engine compartment.

The AC fan control module controls both the blower motor inside the cabin, and the cooling fans in front of the radiator. If the module fails or begins to experience problems, you may notice that your cooling fans run for a very long time, or don’t run at all. You may also experience problems with the blower motor inside the cabin.

The AC fan control module is an electronic component, and because it’s mounted inside the engine compartment, it’s subject to high temperatures that may cause damage over time. It may also experience electrical problems, including wiring damage. There are also other problems that can mimic AC fan control module failure.

Keep in mind:

  • AC fan control module operation is not checked during maintenance service.
  • Relay failure and other problems can mimic AC fan control module failure.

How it's done:

  • The AC fan control module is verified that it needs to be replaced
  • The defective AC fan control module is removed
  • The new AC fan control module is installed
  • The AC fan control module is tested for operation
  • The AC is tested to ensure proper operation of the AC fan control module

Our recommendation:

The AC fan control module is responsible for operating a significant number of components on your car, but because it’s an electronic component and relies on other parts for operation, there are many potential issues that could render it inoperable. As such, if you suspect a problem with your AC fan control module or another AC problem, have one of our expert mechanics inspect and repair it as required.

What common symptoms indicate you may need to replace the AC Fan Control Module?

  • Cooling fans run for longer than normal after car is turned off when outside temperature is not high
  • Cooling fans inoperable
  • AC does not operate (blower will not work but compressor turns on)

How important is this service?

While the AC fan control module is responsible for controlling both the blower motor and the cooling fans, there are other components here that could be the culprit. These range from the fan resistor pack to the fan relay and more. We recommend having our expert mechanics diagnose the system to determine the actual underlying problem.
