How Long Does an AC Fan Control Module Last?

The AC fan control module is what controls both the cooling fans in the front of your car’s radiator, and the blower motor in the passenger compartment. It is mounted within the engine compartment, and that means that it is vulnerable to high temperatures, as well as damage to the wiring that could be caused by road dirt and debris blowing up into the motor compartment.

How long your AC fan control module will last depends on a variety of factors – how often you drive, the conditions in which you drive, the possibility of contamination from blowing engine oil, whether you live in an area where salt and sand are used on the roads in the winter, etc. Generally speaking, though, the AC fan control module is not a component that you should expect to last the life of your vehicle. You will likely have to replace it every 3-4 years.

Signs that your AC fan control module needs to be replaced include:

  • Fans run for too long
  • Fans do not run at all
  • Fans run even when outside temperature is low
  • Air conditioner turns on, but does not deliver cool air

If you think that your AC fan control module needs to be replaced, consult a professional mechanic for a diagnosis. An experienced mechanic can check your air conditioning system to determine where the problem lies, and if necessary, can replace your AC fan control module for you so that you can continue to drive in comfort.
