This heater fan resistor is located in the heating and air conditioning blower motor housing, this is easily accessible from under the glove box. Its job is to control the various speeds of your interior fan. When this resistor fails, you will often find that your fan only works on the highest setting, or you lose some of the lower speed settings completely. This is a common failure point in the D40 and R51 models.
Leaving a faulty resistor unfixed means you lose proper control over your vehicle's climate system. This can be a serious inconvenience for demisting the windscreen in winter or for maintaining comfortable airflow without having the fan blasting on full speed.
