The heater fan is part of your car's climate control system. It is a unit made up of a motor that blows air into the cabin of the car. It not only blows hot air when the heater is on, but also cold air. In addition, it circulates air through the cabin to ensure a continuous and fresh air supply.
Over time, the heater fan motor may wear out and fail. In many cases, it should be cheaper to replace the heater blower unit entirely than to replace the parts individually . Sometimes a faulty heater fan can also be due to a bad electrical connection, for example due to a connector that had to withstand an excessive amount of heat and subsequently started to melt. In this case, simply replace the connector.
